Enhance Elemental

You pour your arcane energy into an elemental creature within range and enhance them. Your target transforms into a crystallized version of themselves--becoming ruby for fire, sapphire for water, topaz for earth, and diamond for air. In their new forms, the creature gains a +2 to AC, resistance to damage from spells, immunity to force damage, +4 to strength, -4 to dexterity, and a +2 to constitution. In addition, the creature becomes sensitive to the arcane energy around him and is permanently under the effects of the spell Detect Magic.
