If a level 6 Path of the Ancestral Guardian Barbarian is hit by an attack, can he use his reaction to Spirit Shield himself?
The Spirit Shield feature (XGtE, p. 10) says:
Beginning at 6th level, the guardian spirits that aid you can provide supernatural protection to those you defend. If you are raging and a creature you can see within 30 feet of you takes damage, you can use your reaction to reduce that damage by 2d6.
When you reach certain levels in this class, you can reduce the damage by more: by 3d6 at 10th level and by 4d6 at 14th level.
This extends to creatures the Barbarian can "see", but can he "see" himself and reduce damage dealt to himself? Or does this only apply to other creatures?
