Axe Beak - Weak to water, Palamena is a must have if you want to beat it fast, Light and Water vessel are super effective, Just spam trigger and Breaks when available easy boss fight.
Vaulchibel Benevodon of Fire - Same strategy against Axe beak
Daelophos - Phase 1 he is weak to dark element, Shade vessel and dark saber and spells are recommended. 2nd Phase changes form to shadow and now is weak to the light element, so prep on that. And also you can Stagger or knock him back if you can accumulate lots of damage, You can also freeze him.
