The model’s Strength profile is improved by 1 for riding a Thunderwolf. This is not a modified profile, but is instead the model’s new profile (as demonstrated by the Thunderwolf Cavalry profile). As wielding a power fist or thunder hammer doubles the Strength characteristic on the model’s profile before any other modifiers are applied, this will mean the model’s Strength of 5 is doubled to 10.

Yes.

Then he will simply have no ranged weapon. This is to cater for the Librarian Terminator model, which can be assembled either with an outstretched hand or a storm bolter; the same options therefore apply to Librarians in Codex: Space Marines.

It is effectively Terminator armour, so no, a model wearing the Armour of Asvald Stormwrack cannot ride a Thunderwolf.

The two rules effectively cancel each other out. In the case of the Pelt of Balewolf, a model with the Daemonic Instability special rule would therefore have to take a standard Fear test.

Ignore the Drop Pod Assault special rule for the Drop Pod from the Wolf Guard Thunderstrike Formation.

There are two different Iron Priest options at present, and you should feel free to use either or both in your army. One is an Elites choice, which uses all of the rules described in Codex: Space Wolves, whilst the version in White Dwarf and War Zone Fenris: Curse of the Wulfen is obviously a more senior version, with an improved profile and weapon options, hence the reason he is an HQ choice and has a higher points cost.

Roll one dice to determine the effect of the Curse of the Wulfen for all units of Wulfen in your army.

No.

The Independent Character is affected by the Curse of the Wulfen special rule as normal; only the Wulfen themselves are unaffected.

No.

Yes. The slain Wulfen model strikes back at the end of the Initiative step in which it was slain. For example, in the case of a Hammer of Wrath attack, which is resolved at Initiative step 10, the Wulfen strikes back at the end of Initiative step 10; in the case of a Stomp attack, which is resolved at Initiative step 1, the Wulfen strikes back at the end of Initiative step 1.

They must use the Relics of the Fang from Codex: Space Wolves. However, if you wish, a Wolf Guard Battle Leader from the Champions of Fenris Formation from War Zone Fenris: Curse of the Wulfen can instead choose a single Relic of the Great Wolf from Champions of Fenris.

Yes.

Provided that the Formation’s Iron Priest is still alive, the Formation’s Wolf Priest, Rune Priest and Iron Priest can each ignore their first failed saving throw each phase. This does not apply to any accompanying Cyberwolves.

No.

No. Power of the Machine Spirit allows a vehicle to fire an additional weapon – one not fired already – not to fire a weapon for the second time.

The attached character does not benefit, but nor does he prevent the unit he is attached to from doing so, provided that all models in the unit (including the Independent Character) maintain unit coherency.

If Stormrider is destroyed, Logan Grimnar is slain as well.

Wulfen wear armour over their black carapace that has been customised according to their unique physiology, but it offers them no in-game effect beyond a standard 4+ armour save.

No. Do not count units of Wulfen that are embarked at the start of the turn for the purposes of the Curse of the Wulfen special rule.

Yes.

These items are unique to the version of the Iron Priest with the HQ Battlefield Role from White Dwarf and War Zone Fenris: Curse of the Wulfen.

The Formation limits you to 1 Wolf Lord, 1 unit of Grey Hunters, and 1 unit of Thunderwolf Cavalry; you cannot add any further units to this Formation. A unit of Grey Hunters can have a maximum of 10 models, so you cannot add any more of them, while a unit of Thunderwolf Cavalry can have a maximum of six models, so you may add three more Thunderwolf Cavalry models to the Formation as part of that unit.

No.

If a unit from a Daemonic Incursion is within 3" of a corrupted Objective Marker and an enemy unit is also within 3" of that Objective Marker, the Objective Marker is contested. If either of these units has Objective Secured, the objective belongs to them (if this is the non-Daemon player, the objective would also be cleansed).

Yes. Any scoring unit can cleanse an objective so long as the Daemon player doesn’t have a unit within 3".

No. Only an Exalted Alluress riding a Seeker Chariot or Exalted Seeker Chariot can take the Whips of Agony.

Yes.

When using Shared Power, the other models in the Infernal Tetrad have the same Warlord Trait that you generate for your Warlord. This affects each of the Daemon Princes as if they were your Warlord, and they each benefit individually from the rule. For example, if you generated the Savage Hedonist Warlord Trait, you would add 1 to the Attacks characteristic of each of the models, not 4 to the Attacks characteristic of your Warlord. The effects are never cumulative – a unit within 7" of two or more models with the Miasma of Pestilence Warlord Trait would only suffer D6 additional Strength 1 hits with the Poisoned special rule at the end of the phase, not 2D6 or more. For another example, if the models in the Infernal Tetrad have the Strategic Genius Warlord Trait, you would only add 1 to your roll to Seize the Initiative, not 4.

Only the model originally chosen to be your Warlord awards a Victory Point for Slay the Warlord.

In this circumstance, Shared Power does not apply to Daemon Princes of Khorne.

No. You could use a re-roll on the dice you have ‘flipped’ or use the ‘flip’ on re-rolled dice.

Yes.

Yes.
