Each enemy Attack Level has different classification:
Guard break means held-down Royalguard breaks and Dante takes damage. Guard/Ultimate being impossible lead to knockback and damage.
Enemy elemental resistances are in percentage eg. 100 means an enemy takes 100% damage, 95 means only 95% damage and 105 means 105% damage.
Attack Rate means the melee and ranged damage resistance an enemy has, eg. 100 is 100% and 30 is 30%.
