Feat
Multiple Barrier
Creates several Barriers simultaneously
When casting Barrier, the character may create fitted Barriers on several different targets within range. The maximum number of targets equals Intelligence divided by 5, rounded down. All Barriers belong to one casting and share its spell level and duration.
Choose one mode when casting:
Division. Use one spell slot and divide one normal Barrier's HP among the targets in any proportion.
Full strength. Each target receives a Barrier with its full normal HP. The first uses the casting's normal spell slot; each additional target costs one additional spell slot of the same level.
