Umbra of Providence

Roll a d20 for constitution, must have a roll of 10 or higher to be able to cast. Providence casts an umbra of himself that copies his attacks, (does not cast spells). Can only be casted when below 40% hp, damage increases the lower the hp: 40% = 1.5x, 30% = 1.75x, 20% = 2.25x. Umbra disappears when Providence either dies, disables Umbra, is out of combat, or is healed above 40% hp. Umbra cannot be damaged by any attacks and doesn't make the hitbox of Providence any bigger. This spell can only be used for close range offence and cannot be sent to save another party member unless Providence tries to themselves. Does not affect saving throws.
