XP (short for experience) is collected to level up.
After collecting a certain amount of XP, the player levels up and can pick a new upgrade or synergy out of a random selection of 5 (or 4 when playing on Darkness level 9+). During the level up process, the game pauses and afterwards all enemies are pushed away from the player.
XP can be dropped from enemies: Every Small enemy drops an XP orb worth one XP. Elite enemies drop a chest containing 36 XP (in addition to a Character Upgrade). Bosses do not drop any XP.
Certain upgrades can increase your XP gain, or trigger special effects when you collect XP orbs:
