Retaliation question

Does “Increased damage to X enemy type” affect retaliation/reflect damage

Edit : Also how do proc’s of the same kind stack, eg. if u had 3 items with “of Squalls” suffix
(5% chance on attack to do some lightning damage)

No.

Each gear item gets checked separately. Meaning if you have 3 of the same effect like a 5% chance to cast a fireball all 3 of those will be rolled and executed separately.

If you plan on going for retaliation check on MRGA.
