QoL wishes:

Combine mutually exclusive buttons to lower bloat - F4/B4/Enochian, Ley Lines/Between the Lines

Turn B2 into a targetable spell like Freeze, and make it upgrade into Freeze.

Lower the MP cost and possibly increase F2 potency.

New Skill Ideas:

Necrogenesis - next three speels return 10%dmg as HP (give us a self-heal for peet's sake!)

Burst/Comet - double Polyglot stack skill for burst phases

A way to instantly generate 2 Polyglot stacks.

Do something with F1 (maybe F5 as an instant cast AF refresh as suggested before).
