Just two changes really:
1) Lightning Spire reworked-
No longer arcs lightning at metallic units.
Instead, now shoots lightning at up to 4 nearby enemies each turn (upgradable to shoot at more of course- and also upgradable to shoot through walls and/or debuff lightning resist on hit).
2) Fixed a bug involving shrine compatibility- specifically, shrines labelled as not for conjuration spells now require a sorcery OR an enchantment tag, rather than requiring a sorcery tag.
