Xeryn's Force Shield

A shimmering sphere of force surrounds the caster in a 10 foot radius, shielding anyone inside it from harm against attacks that originate from outside the sphere. The shield has a number of hit points equal to 10 plus the caster's spell modifier. Any damage that would have been taken by those inside is absorbed by the shield instead. If the shield is reduced to 0 hit points, the remaining damage will affect those inside. The sphere remains in place until it reaches 0 hit points or the end of the caster's next turn, whichever comes first. Creatures outside the sphere may enter the sphere but doing so requires strength greater than 13 and 10 feet of movement.
