What's new

  • Titan bosses rebalanced: spells now hit them as if they still had their old health (16.7x on the Knight, 40x on the Asura, 62.5x on the Avatar, within the 1% per hit and 4% per second caps), so fast-hitting spells bring them down quickest. Their attacks on players with more than 1,000 max health hit a third as hard (about 0.8 to 8% per attack). Melee, arrows and normal-health players are unchanged.
  • Inverted Dagger: one clean blade (the side prong is gone), and true damage to the titan bosses that ignores their caps. Its Chain Hook now reaches 14 blocks with an 8-second cooldown, pulls a hooked mob to you, or pulls you to it while sneaking, when it hooks a boss, or onto a block like a grapple.
  • Celestial Sanctuary: the Dharma Seal is no longer used up when it summons the Knight; when the Knight dies, a portal home opens by the Dharma Altar until the next fight; the plaza's exit portal no longer disappears after a reload.
  • New game rule calamityBosses: set it to false to skip the boss fights. Each summoning item, used on its altar, gives that boss's rewards without a fight (the item is used up), and boss rewards also turn up in Ash Citadel, sky-city and Ancient City chests, even unopened ones in existing worlds.
