Update: Rift 1.8 Hotfix 13

INFERNAL DAWN [Raid]

 * Players will now be locked to an Infernal Dawn instance after defeating either Gorlach, Bouldergut, or Muglak.
 * Maelforge:
 * Players can no longer cast spells while enveloped by Pyreflies.
 * After reviewing the Spires phase of the Maelforge encounter, we've made some changes to deal with the under-tuned minion effects intended to engage melee character play. We've also looked into other concerns from melee specs and have added a mechanism for melee characters to fight Maelforge directly, provided by defeating Spire minions.
 * Spire minion health reduced slightly.
 * Increased the effect and duration of Maelforge's Sacrifice buffs.
 * Spire minions now grant a buff to nearby players when defeated, increasing their melee damage and providing them immunity to Maelforge's cone attacks. Tank targeting effects and buffs negate this melee boost.
 * Added more checks to the start of phase 4 to prevent it from activating early.

GENERAL

 * Fixed odd camera behavior while your character is polymorphed and on non-level terrain.
 * Added safeguards against equipment procs remaining active even though the source item was unequipped.
