More ways to generate Addersting, preferably ways that don't cost GCD heals, because Toxikon is not built to be a GCD-heal-refund like Afflatus Misery, it's Ruin II, a movement/weave tool. Perhaps Phlegma generates 1 Addersting every time it's used to form a sort of loose combo system.
New skill: Eukrasian Toxikon, potency changed to 450 and 75% less for remaining enemies. The rationale here is Toxikon is a dps neutral movement/weaving tool, but if you Eukrasia it, you spend your weave window for additional damage, like sticking an Energy Drain in there.
