This spell summons a quantity of this ectoplasmic slime, from wherever it originates, to cover the caster as a cloak, It is highly acidic, and although it will disintegrate whatever the caster is carrying or wearing (barring items of eldritch power), it will not burn the caster's body. The ectoplasm generates a number of effects that the cast may take advantage of:

• The ectoplasmic robe confers AC of 15 on the caster, Any successful strike against the caster erodes the attacking weapon, lowering its maximum possible damage by once. A standard sword that does 1d8 damage will thereafter do 1d6 damage, for instance. Attacks using natural body parts will inflict 1d4 damage on the attacker instead. Attacks with blunt weapons will do an additional 1d4 acid damage to the attacker as the ectoplasm splashes, unless the attacker makes a saving throw DC 8+profiency bonus+dexterity modifier.
  
  
• The caster's touch becomes acidic, and can melt even the strongest metals within a minute. The caster may attack with her body, doing 1d8 damage on a successful strike. Even unsuccessful stikes, if the roll is still 12 or greater, will lower the AC of the target by 1 if they are wearing actual armor.
  
  
• The caster may throw the ectoplasm (range categories 10'/20'), which does 1d6 damage if it hits, and unless the target makes a saving throw DC 8+profiency bonus+dexterity modifier, it does 1d4 acid damage, If the target takes damage and wears armor, their AC is reduced by 1.
  
  
• The caster can breathe the ectoplasm itself, gaining protection from gas, drowning, or other respiratory hazards.
