Gemini Pendant

Once per day, the wearer of this magic pendant
can create an identical copy of themselves that
lasts for 1 min/level. The copy has no attacks or abilities, and does not copy any magical items or effects of the caster. The copy can be controlled independently of the caster, and shares all skills
with them. If the copy is dealt damage equal to
10% of the caster's max HP, it disappears.
