I almost always start the fight with this pet, even in a bad matchup. Top priority is applying Colmillo venenoso
(note the dot deals elemental damage). This will punish the enemy when he swaps the pet out.
Pretty simple priority list:
#1 Acid Rain when no cleansing rain is up (you might want to hold it back to stop a dangerous enemy weather combo)
#2 Acid Rain when three enemy pets are alive (does more damage than Dreadful Breath when cleansing rain is active)
#3 Dreadful Breath vs 3 enemy pets
#4 Toxic Smoke against enemy beast (<3 enemy pets)
TCS is quite frankly broken. Not only does the Meteorito Crepuscular
far too much damage by itself but if you combine it with the Dragonkin passive all hell is loose.
Watch out for the cooldown on the abilities, it makes the difference between a dangerous TCS and a team destroying one. The perfect rotation would look like that: 1-2-1(passive proccs)-3. But don't let it die, it's the main damage dealer of this team
You can also start the fight with it. Play 1-2-1. Against most enemy pets your racial will now have triggered so you can use Meteorito Crepuscular
. After that swap it out for another pet. This way you can do the same rotation later again.
