Trident of Capture:
:0 [Start Skill]
Engage 3 random units of level 2 or lower and AT 60 or higher.
Now does this mean these two categories have to be satisfied simultaneously? Or is that "and" supposed to be a "and/or"?
As for Tidal Wave, when it says "send a Grimoire card from your file to the Cemetery, is it random? Or do you get to choose?"
I can't test these out right now, if anyone is willing to help me out, then thanks in advance.
