These will probably become much more viable with Soul Armor. I could see Raicho mode being really helpful in particular.
Pretty impressed you can get this far with just one summon, I would have put the cap at Tower:3-4 or so.
I'm actually surprised the Wisp did that too... I think the AI may be over-valuing Ignite at the moment. I'll take a look at that.
Emit Sparks is a random target effect. It was a bug to block it during Pele's recruitment since Pele is actually friendly... but in the case where the target remains hostile, it definitely is intended to not be an option. I'll see if I can find a way to communicate this better.
I'll also look into the lock-up bug w/ no internet too. Thanks for the report and bug info.
