The Prince Archetype has various moves that are exclusive to him and are very powerful to use. Hero's Cry adds four more Turns Icons once in battle.

We highly recommend using Hero's Cry at the start of the battle to make sure to buff, debuff, and do the maximum amount of damage you can do in one turn before Diabolus Avades can even attack.

Use Prince's Almighty Skills

The Prince Archetype also has access to various different Almighty skills that won't be blocked by any resistances from bosses.

Use Synthesis skills like Royal Sword as well as moves such as Royal Slash to deal big damage to Diabolus Avades.

Take down the Hands with Fire

Since the weaknesses of Diabolus Avades is the same as Homo Avades, taking down the Hands with Fire is stil viable to gain extra Turns.

Use multi-hit Fire spells like Ruin's Flameflower to hit both at the same time.
