Battle Link

When you cast this spell, you target one friendly unit in 30ft. You two have become linked. The linked target gains +1 AC, +2 to attack and damage, and 2d10 temp hp instantly when becoming merged. This spell lasts for 1 minute, and can be dispelled safely. If you lose concentration unwillingly or without the spell's natural duration ending, the linked creature takes 2d10 psychic damage, and must make a wisdom save against your spell DC, on a failure, the creature is stunned for 1d6 rounds. The link has a range of 30 ft from the caster, exiting this area will unlink the creature, and cause the adverse effect of unwillingly losing your concentration. Casting this spell at a level higher than 2, will grant the linked creature and additional 1d10 temporary HP.
