Note: As of the update on on the 26th of October, 2021, DKH is a mechanic that will only work in the OG Spells game mode.
Explanation[]
In Arcanists 2, Dark Knight Hump (DKH) is a technique in which Dark Knight's "Charge" spell damage is maximized by aiming at a very specific spot. This causes the Dark Knight to move up and down in the same spot repeatedly rather than moving down through terrain.
DKH is typically used when the Dark Knight is on top of the target at a slight offset from center. This offset is important as it increases the time that the "Charge" hitbox is in contact with the target, increasing damage by around 15 on a normal sized player target.
It should be noted that some reference points in the sprite art used by players to aim "Charge" are different between Dark Knight, Zombie Dark Knight, and Dark Paladin.
