Assassin specialized quests?Follow

I don't think so. But then it's been some years since my assassin was a wee one.

I think really your best bet is to harvest rares and find an armorer and weaponsmith that can make you new gear for each tier.

Jewlers make all your spells, and never underestimate the power of poisons.

Assassin is a great class. If you have any questions feel free to ask, I would be happy to help.
