Notes
Col is particularly excellent in the early- to mid- game, and also on stages where the enemies are weak enough to be taken out in a single attack, as her trait gives her a second action whenever she defeats an enemy with a back attack or attack from the side (at five-star, she can do this every single turn).
Her nuke, Wipe Out, is handy, as it allows her to (as long as no ally is within two tiles of her) ignore assisting cover. This attack often means instant death for random mobs, particularly if she has a bunch of Devil stacks already.
Because of the condition of Wipe Out (and also her preferred trinket), she likes to wander off on her own, so just be careful where you leave her, or she just might die on you.
Omen of Death is incredible for her, as the [Feverish Beast] stacks are granted even if she isn’t the one killing enemies, so it stacks beautifully alongside Devil stacks.
I personally prefer the Alacrity leader aura on her, as it’s an easy, stable source of Crit and Crit DMG, and benefits others, as well. That being said, you can bring Mask, instead, just be aware that she becomes a Mask-junkie on auto and will bravely run up to enemies she could easily kill and uses Mask instead.
One could choose her unique basic attack over the one I suggested, but I tend to find that the extra Crit is more useful than the [Ignore Assist], as you can use Wipe Out for that anyway.
For a weapon, definitely use Void Stab for the Crit-related bonuses. For a trinket, you’ll want Maverick’s Cloak, as it works perfectly for her playstyle. For a tarot, Devil is her best, and it’s not even close. Once she ramps up with it, she becomes a monster. For engravings, go with wand + sword, as she moves around a lot anyway. When rolling stats, aim for P.ATK.
