I know that somewhere there are answers, but they are hard to find everything in one place.
1. Class skills it a spell? (Templar's Aedric Spear, etc.)
2. If it a spell - Jaggernaut passive bonus a useless for this? (This is logical because they use mana, but the game is too many strange things)
3. If it a spell, attack modificator of weapon don't work for them?
4. "Power" and attack of weapon are equivalent?
I know that DD is desirable to walk in light or medium armor bonuses due to mana or stamina, but also i do not want to die by running into a magical robe, so I do think the 5 +2 or 5 +1 +1.
