As a single target hero with additional AoE and random burns, Twinfiend's initial damage can seem underwhelming but he is an infernal lord with a very fast regen and has some nice AoE damage on his ‘focus fire’ ultimate. Twinfiend's lord skill comes with the addition of boosting his faction's crit during and after the focus fire, but unfortunately he needs to be A1 to apply the vulnerabilities Pyros does as a standard thing.
