"We need to make poison damage enemies over time instead.
We need to make freeze freeze them solid as a block for a random amount of time
We need to make fire cause damage over time and reduce the enemy's attacks by half damage
We need to make shock paralyze targets
We need to make sleep no longer heal the enemy, and also let sleeped enemies take damage while sleeped but wake up faster
We need to make stun just cause enemies to flinch, cancelling their attacks
We need to make curse slow down the enemy, but also increase their attack and defense
We need to make Kats cause curse. But when Kats cause curse, they lose health but the cursed enemy takes damage over time.
And we also need to add confusion. Confused enemies will have a chance to damage themselves on an attack."
