Fenrir close to direwolves cause the direwolves' eyes to glow, and gives them a buff which reduces incoming damage by ~12.5% and increases damage output by ~25%. This buff can stack with mate boost, pack bonus, howl, and yuti roar.
Mostly PVE tame. Concept for PVP Tame is there but just too far behind in stats. Each tier of Fenrirsulfir Boss gives a higher level Fenrir. It has a good slow and an area freeze, but this is a one time use if you take it to PVP its going to die to get that freeze in.
Still good for PVE, makes wyvern milk and nameless venom last 2 days in inventory. Ambergirs is extended too I think. Does NOT affect Antidote or Primal Crystals at this time.
If Ark wants this to be more than a souped up Hyeanadon, they need to make it breedable.
Up to help someone with fridge info or to get Ark to make it breedable. Maybe.
