Very nice suggestions thanks Wutan. A few things just my biased opinion on this. I did not (and still do not) like Epidendrum's design/looks from day one. Aside from being lucky and pulling her from gatcha, I do not see myself getting her anyone soon, or ever o_O ; and yeah I like to play defensive so debuff is nice, maybe focus on that 1st...

So in the end, we have approx., assuming 2-3+ turns passed: up to 250-300% ATK boost, 50-70% debuff, 1.6x - 1.76x Skill Act, so maybe okay set-up?

The last slot, I also really want a heal, but anyone who has a "Overlimit" skill, doesn't have 1/2x Skill Act; I also maybe am thinking about Easter Cactus, 'cuz coming back from the dead... but dunno if I should sacrifice one of the above for her or not.
