At 1st level, a shadow puppeteer can use bardic performance to create one quasi-real shadowy creature resembling a monster from the summon monster I list. These shadowy creatures otherwise work like shadow conjuration, and targets interacting with them get a Will saving throw (DC 10 + 1/2 your bard level + your Charisma bonus) to treat them as only 20% real. At 4th level and every three levels thereafter, this ability acts like the next higher version of summon monster (summon monster II at 4th level and so on).
