Version History

 * Anniversary Update
 * Gameplay Changes
 * Changed summoned pre-stack scaling from current-difficulty-based hp + damage bonuses to leveling up to the ambient level like other summoned characters
 * Summoned Aurelionite attention span: 5s ⇒ 15s Developer Notes: Aurelionite’s raised attention span should make it less likely to get distracted by weaker monsters attacking it so it’s more likely to spend its time fighting stronger monsters.
