- Apply Pyro on enemy (recommended to use Bennett burst for ATK increase)
- Use Mona Burst (should react and remove Pyro status on the enemy after using Burst)
- Wait 2.5 seconds for Mona’s burst ICD (Mona should stay on field if you have Bennett, to keep the buff)
- Swap to Pyro character and apply Pyro on enemy.
- Burst will pop after enemy gets hit, applying Hydro and vaporising her damage.
