@ Willbachbakal: I'll enlist the current attack progressions.

This not to mention that there are also exists the idea of abilities being modified by the attack progression (There exists only one case so far, Awilix's W).
 * None.
 * Variable damage progression in numbered strike intervals. Most commonly measured in 3, but exists special cases.
 * Variable AS progression in numbered strike intervals. Most commonly measured in 3, but exists special cases.
 * Ground targeted AoE. Applies on-hit effects at one-third effectiveness.
 * Hybrid range (Melee strikes with a Ranged units' reach). On-hit effects are altered depending of the distance of between user and target.
 * Conic AoE arround main target. Applies on-hit effects to the main target only.
 * Linear skillshots.
