Make sure your HoTs are active during every boss fight.
Starting fights:
- cleansing ritual
- blood altar
- illustrious healing
- ulfsilds contingency (this is to buff your resource recovery— important especially for last boss in stone garden as that is a particularly resource intensive fight)
- energy orb
As soon as the fight starts, elemental blockade for weakening and off-balance, drop a barrier for savagery (MA buff) then proc PA with echoing vigor. Budding seeds is placed basically on top of the tank. Reset AoE heals every time you move enough for the group to be out of those heals.
Prioritize sticky heals like:
- radiating regen
- combat prayer
- healing contingency
- echoing vigor (also important for keeping up PA)
Most important things to keep in mind:
- elemental blockade is there to proc weakening and off-balance, make sure its cast on cooldown
- last boss is really tough on the tank, keep synergies fresh and available to the tank (altar, orb, seeds, ritual)
- recast ritual when you move to a new area
- keep up altar and orb basically as much as possible
