I'm playing through as a pure Mage, and I currently only have 3 skills mapped. However there are 7 skills in my abilities tree but only 4 available buttons: holding RT and then A, B, X or Y. If I were to purchase all 7 skills, how would they be mapped on the controller?
R-Trigger mapped skills only allows 4?
You can't... because the game's like something out of a by gone era for RPG's =/ (and even then like in something like Oblivion, there was always the wheel). It's fucking lunacy as to why you can only store 4 spells despite they of course offering up quite a few across the three trees. You can at least activate a sustained spell, then remove it from your set and replace it with an active spell but it's still a complete joke.
