Bleeding.

Bleed
Bleeding is caused by a deep laceration and can continue to inflict damage if the damage is not repaired. Bleeding causes D-tier damage each post until the bleeding is stopped or the duration runs out.

D-Tier: Bleed for 1 post.
C-Tier: Bleed for 2 posts.
B-Tier: Bleed for 3 posts.
A-Tier: Bleed for 4 posts.
Ω-Tier: Bleed for 5 posts.

This effect is the worst. It is scaled properly at D and C tiers, but at B and beyond, it's highly underwhelming.
B is supposed to be twice as strong as C, but you only get one more tier of D damage, etc etc etc.

There should be an edit. Also making Omega bleed for 16 posts is humorous, but also not very useful in the long run. Perhaps there should be a different effect, or removed altogether.

It is intended as a supplementary effect and is one of the only ones that does actual damage, it isn't supposed to be truly effective as an offensive spell all on its own, as its not an offensive ability. It is intended more to be used in conjunction with an offensive ability to add an additional effect.
