[Balance] Summon Delin, Pyre of Man is Utterly Useless
For whatever reason, all other combat summon spells take 1 turn to cast. They all cost, at most, 60 mana.
However, summon Pyre of Man has a casting time of 2 turns (total 3 including the initial cast), and costs 500 mana(!!!). Even worse, it's not a permanent summon for the battle, as he disappears after 3 moves.
As it is, the spell is utterly worthless. In fact, going for crag spawn / earth elemental / grave elemental is far superior for meatshields.
Suggestion: Reduce the spell cost to 60 mana or so, and make the casting time 1 turn. Then it might be decent (although even then, I think I'd rather going for the grave elemental and earth elementals over Delin).
