In the Umbral Monument, switch targets to the 2nd charger and kill them in quick succession. This approach makes the encounter significantly easier apart from dealing with the 2 chargers.
For 3rd agony battles (fire rage boss): perfect dodge won't save you if your team is dead. Need to level appropriate elemental teams (cryo, electro) rather than relying on phys/fire teams. No FOMO on temporal rewards if you can't beat it yet.
Team composition for Rhodagn boss: P0 Yvonne with signature weapon, Fluorite (no weapon/gear needed - applies 3 nature infliction to boost Yvonne BS damage), Xaihi with Chivalric (necessity since Detonation Unit's skill cannot be triggered). Xaihi also buffs nature damage. Can be done with P0 Yvonne + sig, Fluorite requires no investment.
Yvonne with Fluorite can defeat Rhodagn in 29 seconds. P0 Yvonne with signature weapon works. Fluorite requires no weapon or gear - her job is to apply 3 nature infliction to boost Yvonne's BS damage. Xaihi buffs nature damage and requires Chivalric gear since Detonation Unit's skill cannot be triggered otherwise. Gil is also part of the comp.
