Envenom

Envenom was a Generic Talent that dealt damage over time to the target enemy Hero. The actual damage dealt per second isn't very high and only hits once per second, but it can be good for securing a kill if you get them low but can't land the last blow. It is targeted and has no cast animation making it excellent for bursting someone down.

Modified version

 * Zagara's level 4 Talent, Envenomed Spines, empowers her next Basic Attack to deal a bonus 230 damage over 5 seconds. 30s cooldown.
 * Thrall's level 7 Talent, Ancestral Wrath, deals damage equal to 15% of the target hero's maximum health over 3 seconds, healing for 150% of the damage dealt. 1s Cooldown, available once Frostwolf Resilience triggers 8 times. This Talent is a blend with another old Generic Talent Thrall once had, Blood for Blood.
