Hmm, interesting stuff. I might try Sunbird/Rowanne/Firebomb/Pharos then and see if one bomb is enough. I have all my troops leveled to max, so right now the slow saving for Dawnbringer starts - surely interrupted soon by Bright Forest troops incoming and wanting to be leveled - so I do wanna keep Pharos if possible. I know that just doing Divinion Fields challenge one with his own team nets me 560 souls a pop, but basically no gold at all, so I kinda like doing slow soul gathering + gold + arcanes in one go right now.
Gonna give Rowanne a shot, though - if the traits aren’t needed, that’s a quick thing since she’s at her max level. I do believe she’s still epic, though… gotta check.
EDIT: Tried a few battles (and even got one Arcane while doing so ) and while it definitely does work, it’s too luck-reliant with just one firebomb. Sometimes both fill up, sometimes just one of them and sometimes - too often for my taste - neither. And if one of them doesn’t clear, I have to fill manually anyway since neither is an exploder, so it doesn’t really matter if I fill Rowanne or Sunbird for a second time for the finishing blow.
Rowanne seems to one-shot far more reliably than Sunbird, but since she depends on armor, I can’t use her as main damagedealer and switch Sunbird out for a second firebomb and putting Pharos in front of her to soak damage up is not doable since he would steal all blue Mana.
So I guess it’s either switching out Pharos for a second Fire Bomb for more speed or keeping my current setup for more souls.
