Each time Archangel triggers a Bleed effect on an opponent with an active Poison effect that he caused, they are combined, converting into a Neurotoxin charge, lasting 15 seconds.
Neurotoxins are a Passive effect, and therefore do not count as either a Debuff, or a Poison.
Neurotoxins do damage over their duration.
On expiry Neurotoxins have a 100% Chance to Stun their target for 1.5 seconds. This effect will not interrupt a Special Attack.
