When the arcanist uses the greater spell disruption exploit, she can siphon some of the power of the targeted spell to restore her arcane reservoir. If the caster level of the spell is equal to or higher than that of the arcanist, and she exceeds the DC of the dispel check by 5 or more, she adds 1 point to her arcane reservoir. If she exceeds this check by 10 or more, she instead adds 2 points to her arcane reservoir. This has no effect on magic items. The arcanist must have the greater spell disruption exploit to select this exploit.
