Boneless

The target's arm and leg bones disolve. The spine, ribs, and skull turn to gel encased in a thin, rubbery membrane. The target falls prone and can move only 1' per round. The target has difficulty breathing and can take no actions, other than spell casting (spell must consist of verbal component only). Spell takes 4 additional rounds to cast.

Blow to target's head deals 10d10 damage.

Can be cured with Heal spell or Greater Restoration. Heal potions (must be administered by another creature) restore bones over 3d4 rounds. Cure Wounds and Healing Word spells restore bones in 8 rounds minus level spell is cast at.
