Multiple Shot's Energy cost prohibited?! 3-10 Energy cost isn't exactly hard to afford. It's not like it drains energy every second like an aura.

I noticed that Way of the Sickening Arrows in-game description was different than the website's description. I assume the change (drop from 35% chance for reduced resistance down to 5% chance) was because the skill was found to be powerful? I'm afraid the new version of the skill is too weak for an exclusive aura (especially given how powerful skills in general seem to be in this mod) since the poison damage is negligible even in Normal and the resistance drop is unreliable. For reference, the Rogue's poison skill gives 230 Poison over 6 seconds at LV12 and it's a tier 1 skill.

I think a good and simple addition to make the Way of the Sickening Arrow more appealing would be to add +% Poison Damage & +% Poison Duration to its list of abilities. Then, at least, it would have synergy with other poison attacks.

And I have to agree with Llian; I'm not finding a ton of synergies amongst the masteries. This isn't necessarily a criticism, just a noticeable difference between the Masteries mod (which seems to be more about flavor and throwing in as many cool ideas for skills as possible) and the regular game (which was all about the synergies).
