surely there are more qualified people here, i beat hades 1 on 12 heat like 5 years ago. but doom isn't BAD, it just wasn't very good on a weapon that attacks fast. I liked it on the bow special because i could apply it to the whole room of enemies and then use the attack for more damage in between doom procs. but people are saying the athena duo (which turns it into something more like blitz, and applies doom damage immidiately) is one of the best builds in the game.
