Here is a skill that scales on INT:
Here is Carve Owl:
If you remember, certain wizard builds are popular with full CON for a reason - this is because most of the Wizard abilities do not scale with INT like it does for certain Cleric skills like Cure or Heal. Going full INT adds laughable damage endgame (around 400~500 damage?) for wizards because most of their abilities have high raw base power already. If you wanna know how I know this, I have a Wizard C3 - Elem C3 - Warlock friend who recently used a stat reset potion and went from full INT to full CON, and the damage difference is absurdly low that going full INT or even 1:1 INT CON would be pointless.
Like most high damage Wizard skills, Owl Carve also does not scale with INT, and as such the damage difference between high INT and no INT is barely noticeable at endgame.
The only reason why INT based DPS cleric classes need INT is specifically for Heal and Cure, which directly scale with INT.
