No one does anything for two turns just so Libya can get +100 mana. Or is that a bad idea?
Alternatively: you get 50 mana now, then the skeleton moves (paralysis), then Seliad moves closer to it (stands to the left of the skeleton's square 2), skips a turn, you restore 50 mana, the skeleton skips a turn (paralysis), and Seliad uses Radiant Storm. But, since we don't know what kind of skeleton it is, this option is riskier – it might dodge. It can't dodge while paralyzed.
I prefer the original plan.
