The Norse Buffs that are not related to this bloodline have been moved into a separate mini-mod called "Norse Buff." All you need to do is activate that mod and everything remains the same (same mod but split into two).


What have been moved to "Norse Mod" is,

Loot from raids has been doubled
The Berserker trait disables fertility (same value as in "chaste" trait); so after you have secured a son, go berserk.
Loot happens every two days (vanilla every four days)

This separates the bloodline features from changes that affect all norse pagan.
