More suggestions (sorry if there are repeats!)

1. Lilies should have a 100% chance to generate on heals/damage spells. None of this RNG garbage. I play AST for that because at least the RNG is really shiny.
2. Lilies will unlock something really cool and worth the effort. One suggestion: Bravery/Faith. Let's do this:

Bravery
Instant Cast
30s recast
0 MP
Range 25y, 0y

Boosts melee/ranged damage/reduces damage taken by 10, 15, 20% (depending on Lily stacks).

Faith
Instant Cast
30s recast
0 MP
Range 25y, 0y

Boosts magic damage/healing potency by 10, 15, 20% (depending on Lily stacks).

FIGHT!
