Like each major patch, patch 5.4 brings some modifications to existing Warcraft battle pets, which include some changes made to the passives of a few types of pets. Each type of pet has a passive that gives it a boost against certain attacks or maneuvers. For example, Elementals have ignored all weather effects (like lightning storms and sunlight).
New passives for battle pets include:
- Aquatic (Old): Aquatic pets take 25% less damage from damage over time spells (DOTs).
- Aquatic (New): Aquatic pets take 50% less damage from DOTs.
- Critter (Old): Crowd control effects are less effective on critters.
- Critter (New): Critters cannot be rooted or stunned and are immune to sleep effects.
- Dragonkin (Old): After bringing a target below 25%, Dragonkin deal 50% more damage.
- Dragonkin (New): After bringing a target below 50%, Dragonkin deal 50% more damage.
- Elemental (Old): All weather effects are ignored by elementals.
- Elemental (New): Elementals ignore negative weather effects.
- Magic (Old): No attack will take more than 40% of a Magic pet's life.
- Magic (New): No attack will take more than 35% of a Magic pet's life.
It's a good idea to keep these pet changes in mind as the changes may impact the future lineup chosen for difficult pet battles.
Other notable changes to pet battles:
- Pets may now be won from bonus rolls that use a Mogu Rune of Fate (in Throne of Thunder) or a Warforged Seal (in Siege of Orgrimmar).
- Players who take too long to make a move in PVP pet battles will experience shorter timers during successive moves.
- Combining 3 family-specific Flawless Battle Stones will reward a general-use Battle Stone
- Training to play with battle pets is cheaper
- Maximum learned pets has risen to 1000 from 650
