Observe and Dash were Faust's main picks for upgrade; they would take twelve skill stones together and leave him with five.
He could choose to upgrade a Silver-grade skill like Shadow of the Mind, but it would take ten skill stones and leave him with seven skill stones, which he couldn't use to upgrade any iron-tier skill.
Besides, he wasn't in desperate need of mental defenses right now.
And with the remaining five skill stones, he could use four to upgrade Light Clones.
He took out and crushed the fifteen stones one by one, then willed them to upgrade his skills.
