Seriously, I’m just confusing myself at the moment trying to get the math to fit ANYTHING that resembles a numerical mean in damage from specials. Once you have applied an attack down the actual real life variation can be enormous. I was just trying out specials on known Bosses and got results of 600-830 from specials and then applied a 34% defense down and got multiple results of 1110-1320. I’m starting to wish I had not started down this rabbit hole.
But as you say: don’t use most specials on a Titan unless they are an attack buff or defense down, set off Sartana, for example, and you lose more than 10 seconds of play when a strong colour can give you 200+ per tile not counting critical attacks.
