1, i'd go thief [assassin] Sorcerer [dragonblood] 8 / 4 or 4/ 8
Doesn't Assassin work for only the first round/opening?
2 yes if you use magic to hide / turn invis
What spells/abilities would that be?
4 yes dual weild is king because [1] things that increase weapon damage such as dipping or magic rings do it to both weapons
Would you still recommend it without dipping?
sneak attack can trigger on both weapons (but only once)
Once per round or first round only?
