I have been playing the Total War Franchise on/off since 2004, after hundreds of hours I solely play on VH and have some pretty sweet map paints WC's and tough campaign victories across the titles (WRE BI Expansion) I have completed some legendary runs on TWS2 including Oda and Ikko Ikki as well.
Following the diabolical mess (In my opinion) of TWR2 and then some of the issues TWW1 I wandered away from the series and after a good 5 year gap from the TW I'd heard some good things about the state of TWWH2 and seeing watching my old buddy LoTW continue to play and seeing old friends like Wealthmonger return to the series on My steam friends list I thought I would hazard a comeback.
My first run as Dawi on VH proved interesting and after completing that I decided upon attempting the current achievemnt with the least percentage of completion, namely the immortal marauders achivement as Norsca!
I managed to bag this achivement in 240 turns, although it took 4 restarts to complete two of which were up to over 160 turns!
After looking through the internet there are a number of conflicting guides and advice, having tried some and measured their effectiveness I recommend the following for Norscan Dominance,
Faction World Wanderers
Wulfriks Skill Tree
Getting Lightening Strike on the blue line ASAP is essential then focus on the yellow line until you get Hunter of Champions as this will enable you to nerf enemy generals in combat, once you have these important skills use the red line to increase the effectiveness of Mammoths for late game, namely Monsters of the North and Hulks of Death.
Finally increase his fighting ability with Melee buffs and hit points and Wulfrik become a bona fide death dealer
Norscan Army Composition
15 x Berserkers - 3 x Marauder Javelin Inf
10 x War Mammoths - 3 x Berserkers - 3 x Marauder Javelin - 2 x Armoured Skin Wolves - 1 x Fire Shamen
10 x War Mammoths - 4 x Marauder Champions - 3 x Marauder Javelin - 2 x Armoured Skin Wolves - 1 x Fire Shamen
Opening Moves Turns 1-20
Key is to not expand too qucikly, build up Ice Drake Fjord's Military Building Capability so you can spam a Berserker stack, take Longship Graveyard around turn 2-3 and then move Wulfrik to complete the capture of the the Ice Tooth Mountains province, once you encounter Throgg defeat him (Turn 19 for me) and confederate Wintertooth But do not Recruit him yet
At this point do not expand any further in Norsca, Use diplomacy every turn to give small gifts to increase your favour with the Helspire Tribe If you can afford it ofc,
The logic behind this is you'll be fighting to the South for the majoirty of the Campaign, Norscan lands are poor and not worth defendeding and confederating Helspire will make you a Great Power who will suddenly be overwelmed by the High and Dark Elven Factions, your economy will become reliant on sacking Bretonnian and Empire Cities and preventing the formation of the ordertide is your No.1 Priority not buidling up pitiful Norscan crap heaps.
In regards to you homelands build only Public Order and Military Buildings in Ice Tooth Mountains. In the Mountains of Hel, Mountains of Naglfari and Trollheim Mountains build only Fur staches and Ruinous Altars for economic and Public order buffs.
Keep around 2-3k as a float in your gold reserves, start other building chains such as defence works once you are flush from looting the south.
Defence of Norsca
By bribing Helspire the only real risk from Norsca comes from the coast, whilst invasions will come they are never life threatening at this stage. Build Guard shacks on the Coast when you have the funds and upgrading to Maureding Militia Buildings will allow you to reasonably face most threats.
A usefull strategy is in times of invasion is to bolster your garrisons with a general and simply recruit regiments of reknown to assist in it's defence, by the time of the bigger threats and inevitable show down with Chaos you'll have so much gold you can build a doom stack solely to defend the blighted North but for now this simple and cheap method is effective.
Destroying the Ordertide Turn 20 - 160
Bretonnia Turn 20-40
Your whole focus now should be on preventing the forces of order confederating, this should be achived by attacking Courenne first, then Reikland finally the High Elves.
When attacking Courenne you'll need 1.5 Armies of Berserker spam ( Recruit 2nd Lord with Infernal Dominace Trait), keep his smaller stack together at all times in Raid Stance with Wulfrik, whenever possible sack whatever settlements you need to keep the wheels turning on your way to Courenne.
At this stage Courenne will most likely be at war with Marianberg and the Skull smashers and have 2 settlemtns, Courenne and L'Anguille, this will be where Norsca begins its offensive against the Ordertide.
Once in Courenne you need to divide their attention and remain in Raiding Stance to allow you to recieve some income and recieve replenishment, L' Anguille should be your first target, only attack if their is no armies around the key to Norsca is engaging the enemy in equal numbers only what 100% necessary.
Sack ASAP and remain outside the settlement in Raidning stance, next turn raise it to the ground and move towards Courenne. Courenne will most likely be able to field a similar number of troops, around 1.5 Stacks.
At this point use your 2nd Lord with the smaller 0.5 stack to lay siege to Courenne, then utilise Wulfrik to assault the other stack outside the walls, wipe it out and return to raiding stance.
You need to achieve victory in this battle with enough forces sustain the siege with the smaller army and Wulfrik in reserve, in the most un-Norscan Style you will maintain the Siege for 6 turns to starve it out, once the garrison recives attition you will see the balance of power move in your favour (Turn 37 in my run) AR the siege and Raise yes thats right raise the city, destroy it and return your armies to raid stance.
If you sack the settlement you'll struggle to defeat the garrison that returns, defeating Courenne early removes the risk of Bretonnia confederating and removes the first pillar from the Ordertide. Whilst not rich you'll have enough to continue expanding elsewhere and with Courenne out of the way you should be looking towards the Empire.
Defeating the Empire Turns 40 - 100
This is where the serious work starts, the Empire are notorious difficult to snuff out, and the majority of my restarted campigns were due to ineffective stratagies in dealing with them. Preventing building higher tier armies is eesential however upon the cusp of defeat they will always confederate another human faction to prevent anhiliation, likewise leaving them too strong will mean they simply gobble up more Vampire Count lands and prolong their demise!
I found the most effective tactic to be mixture of destruction and Diplomacy, destroy whatver you come across espcially Provincial Capital's to prevent them fielding quality opposition. Try to visualise this campaign as Sherman's March to the Sea in the US Civil War, weaken them whilst attempting to get the VC's in on the action.
Once the VC's join the war you will find you can assault the garrisons, sack the settlements to shore up your finances and the VC's assault and hold the settlements the very next turn.
Probably the most important factor in defeating the Empire out right is that due to some sort of scripted safeguard they will expand in Bretonnia, potentially in the walled settlements of Quenelle or Castle Bastonne. This is normally preceeded by them taking the Forts of Helmgart and Fort Berbeges in the Grey Mountains You need to make the destruction of which ever settlements they take in Bretonnia proper your number priority
By ensuring that the Empire remain in Reikland ensures their destruction at your hands and consumpiton by the VC's later on, leave them this area and they will prove undefeatble. This will be coupled by you being unable to keep the High Elves in Check and allow them to confederate Teclis, Arialle and the other half dozen LL's at their disposal, the HE's are the No. 1 Threat to Norsca but prove undefeatble until you have made 100k's in gold from looting the Empire and can field the end game Doom Stacks.
Once you have rooted them out of Bretonnia dont worry about taking Altdorf its now time to Sack and build the Mammoth Doom Stacks that will win you the Campign, work North rainsing Nuln, Talabhiem and Hergig and sacking outlying villages and towns to bolster your economy, this can take some time but buys the time to get 10 War Mammoths ready for Wulfriks Army. Also start sending gifts to build favour with Naggarond in preperation for neutralising the HE.
Small or medium gifts work on 2 levels, 1 to gain Naggarond as an Ally and 2 to bolster Naggaronds efforts against the High Elves, so does the blood soaked gold of the Empire fuel the war against the High Elves and hasten the destruction of the 8 times cursed Order Tide.
If all is going to plan you'll be able to RV with the War Elephant stacks and really focus on destroying the Empire outright, the Empire will be fully engaged on mulitple fronts. The destruction of Middenheim and Salzenmund proved the end of my involvement as the VC's were now well on their way to defeating Karl Franz.
With the threat in the south now out to bed, hope over the gulf of Kislev to unite Norsca by defeating the Helspire lord and begin preparing your armies for the invasion Ulthuan.
Operation Lothern Turn 100 - 170
With Norsca united, immdiatly despacth Wulfrik to Ulthuan, Mistnar the small Island to the North is the closest. Ignore the shrine of Khaine as your goal is work along the eastern edge of Ulthuan sacking everything in your path whilst eliminating any militray capabilities the HE's can field.
Wulfrik can work independantly until reinforcements arrive, if you find the HE's concentrate their forces simply move further around the inner kingdom sacking as you go. To complete the conquest you'll need 3 Doom Stacks of either Mid-End Game quality who can work their way down from Mistnar raising the already ruined settlements, dedicate their destruction to the Serpent in preperation for the Chaos Storyline Narrative.
At this point look to RV Wulfrik and the other 2 stacks in the vicinity of Lothern. Take Lothern, do not sack it and build it up as defensive and Military province. Rebolster your forces whilst Naggarond and Cult of Pleasure finish off the High Elves and raise what you need to get level 3 with the Serpent.
Behold the True Everchosen Turn 170 - 240
At Level 3 you'll now see the scipted chosen challangers arrive, create a 4th Doom Stack in Norsca and move Wulfrik North towards Norsca.
Have your 2 armies continue to sack the remaining HE's provinces in Ulthuan, much like the Empire and the VC's you'll find the DE's gobble up the depleated garrisons.
At this point its now about gaining possession of the required number of Capitals to meet the Victory Conditions, in my run Clan Ritchen and Clan Pestilens had taken most of Lustria and Naggaroth under their possession including Naggorond. With the DE's well established in Ulthuan the way was clear to send the 2 stacks in Ulthuan North to Naggaroth sacking as they went towards capturing Naggarond.
Meanwhile Wulfrik moves toward Norsca to face the challengers, if the oppurtunity arises use the stack in this area to wipe out any that move near Norsca. They will eventually hone in on Wulfrik and you can simply move him towards a setlement and let them attack and you will recieve the garrision as reinforcements but to be honest you dont really need too as you'll have recieved Khilar the Tormentor as an Agent, this Chaos Wizard is an tremendously OP Blender and combined in Wulfrik's doom stack nothing now stands in your way.
After defeating the 1st 2 challangers you will have to use Wulfrik to teleport to meet the final challanger, this is a relatively difficult battle but can be easily won with Wulfrik and Khilar devestating the LL and the Mammoths mopping up the rest. Worth noting the final Chaos challnger will recieve reinforments from the East and West with a Beastmen and Norsca Army, these can cause significant casulties if not handled correctly.
After defeating this final opponent you will recieve a decision dialouge box which asks if you will choose to allign with Archeron or oppose him. Opposing him gives you the 'True Ever Chosen' Campaign effect and a whopping -75% Unit upkeep buff once all the Warrior of Chaos are defeated.
Unlike other factions Chaos event, if you oppose Archeron the Warrior of Chaos solely declare war on you with 6 stacks including Sigvald, Khloek and of course Archeron. Kholek's army presents the biggest challenge but as the Chaos forces split between moving along the Sothern Coast of Norsca towards the Tower of Krakk and the Bay of Blades and attacking Winter Pyre in the North they can taken apart piecemeal if you use Wulfrik and the 4th Doom stack you created to defend Norsca in tandem.
By letting the Chaos stucks divide themsleves between the difficult and spread out terrain defeating them is not a problem, once the stacks are seperated they can be AR's with minimum casulties any settlements they stack can be rebuilt later at a minimum cost.
With the Chaos Event out of the way I then simply increased my armies to 6 Doom Stacks and checked off the remaining Victory conditions in less then 20 turns and joined the 0.3% of TWWH2 players to have defeated the game as Norsca, around 9k players if figures of 3 Million copies sold is to be believed!
So ends my guide, I hope it helps and if anyone has any questions don't hesitate to ask.
Good luck and if in doubt just shout 'MOOOOOOOOAR MAMMOTHS!!!!!!' and all will be well!
