"Inner Fire to all surrounding allies including self" aura

[Quauhtli]

Okay, i actually dont realy want it to be a aura, but my hero (Patriot - realy is almost the same as a Paladin - lol) still needs a "level 6" attack (wich will have 3 levels, 6-12-18) and i want it to be a spell the hero can choose once in a while (say 120 second cooldown) wich makes all surrounding friendly units including self gain damage, like 50 damage or something - just say what u think is fair - but what should i base this abuility on, and dont say ressurection caus then all the patriots "special, unique" abilitys are based on all the paladins abilitys

im not sure but i think i should base it on tranquility or something
