Werebear Skill +% Damage Bonus?

The Werebear Skill says that it increases the Damage %. My question is, does increasing the Werebear skill increase the damage of say a skill like Armageddon? Obviously, it wouldn’t increase the fire damage from Armageddon, but Armageddon also deals physical damage and I’m wondering if that physical damage increases (similar to Fissure skills points) when Werebear points go up.
