There is no single rotation but the important thing is to always keep 10 stacks of burn on the target so you can amplify the damage thanks to the passive, Another thing to keep in mind is to always insert a CDby doing so the passive will continue to heal you for any damage you deal thanks to the passive
ALWAYS INSERT BUFFS AT THE BEGINNING:
MAIN BURN :
SECONDARY BURN:X2
IMPORTANT: Once you have inserted the burn stacks any fire skill will reset the debuff CD
AT 10 STACKS OF BURNING USE:
can be replaced with : for fights vs RAID and WORLD BOSS
