This is a really well thought out, but I have a couple of suggestions:
1: shroud of wind 2 before mental clarity. Levitation and reflection are two of the most powerful effects in the game.
2: duelist lunge 2 ASAP. if you have to pass up disengage 2 that's fine. Disengage is not half as useful as being able to functionally 1 shot an entire swarm at 0 cost. also strafe attack is definitely worth it lvl 1 or 2 but at least get it.
3: Why discord 2? it's less then a 50% power increase. I would go for something else but if i'm being narrow minded here, let me know.
I think that's about it! Thanks Random595 for another great resource.
