Upon receiving damage from a non-transcendent non-NPC skill, the player learns that skill with each subsequent skill learned replacing the previous. The learned skill level is the lower value between the user's skill level and the player's Imitate level. It is possible to learn skills the player already knows through their skill tree, when this occurs the player may use the highest known level between them.

Learned skills are identical to their original counterparts, including catalysts and prerequisites. For this reason, many skills are ineligible for use as the player cannot satisify their cast criteria, e.g. a Rogue is unable to equip a 1H or 2H Spear and consequently cannot cast Spear Boomerang. The following skills may be readily learned and cast.
