Venom Talismans on a group attacker (I use Phantom Eddie) are excellent. Warlord are probably better for the elite of pvp and gauntlet though.

Extra damage is always good
Crave is an excellent debuff
Exhaust is great (especially in Night City)
Bloodlust healing triggers for the attack that inflicted it, so a multi hitter group attacker with venom talismans can do massive healing and inflict many debuffs
