Almost all existing
enhancements for Artificer Iron Defender and Druid Wolf pets
are now granted automatically as those pets go up in level. (The ones that are not automatically granted are specifically called out below, all other existing ones are). The level they gain them at is the same as the previous Minimum Level for those Enhancements.
For Iron Defender pets, Alignment enhancements are not automatically granted, as they are mutually exclusive. You can now talk to any Artificer trainer to select your Pet's Alignment, which is now displayed as an effect on your pet. Your selections remain until changed or until you Reincarnate. The Chaotic selection continues to provide the Breaker of Boxes behavior.
For both Iron Defender and Wolf pets, Threat Generation/Reduction enhancements are not automatically granted, as they are mutually exclusive. You can now talk to any Artificer or Druid trainer (depending on your pet) to select -40% Threat from Melee Attacks, +0% Threat from Melee Attacks, or +100% Threat from Melee Attacks. Your selections remain until changed or until you Reincarnate, and stack with all other sources of Increased or Reduced Melee Threat.
