The way I read it, he grants the plus 10 dmg to the base dmg, so it would apply on both attacks. Am I wrong here?
Only subtly wrong.
It is a +10 damage bonus, so it does apply to both attacks. However, it does not change a character's base damage. The base damage is what is doubled on a critical hit. For example, a critical hit by Dash Rendar, Renegade Smuggler on an activated, adjacent enemy while within 6 squares of Darth Bandon: 10 base damage (x2 for the critical hit) + 10 (Opportunist) + 10 (Darth Bandon's CE) = 40 damage total.
Very few abilities in the game change a character's base damage - almost all are bonuses. The only things that come to mind that actually change the base damage are the Yuuzhan Vong Shaper (Shaper +10) and GenoHaradan Assassin (Poisoned Blade).
