You can channel incantations that arc to hit other targets in addition to the primary target.
Benefit: You can chain any incantation that affects a single target and that deals hit point damage. After the primary target is struck, the incantation can arc to a secondary target. The secondary arc strikes one target and deal half as much damage as the primary one did (round down). However, you must make a successful attack roll against the target or the target must fail a saving throw against the incantation, as appropriate for the incantation.
However, you may also affect additional targets. The incantation may also strike a number of additional targets equal to one-half your channeler level (maximum ten). Each strike deals one target and deals half as much damage as the strike before it did (rounded down).
Each target gets to make a saving throw, if one is allowed by the incantation. You choose secondary targets as you like, but each target must be within one-half the incantation’s range of the target before it, and no target can be struck more than once. You can choose to affect fewer secondary targets than the maximum (to avoid allies in the area, for example).
Using this feat if the incantation affects one additional target increases the incantation point cost of the incantation by 2 (if the incantation strikes one additional target) or 6 (if the incantation strikes a number of targets up to one-half your channeler level). The incantation’s total cost cannot exceed your channeler level.
