You touch a creature and enchant it with an indescribable allure increasing all Charisma-based skills and spellcasting. For the duration, the target has a +4 to its Charisma score adding +2 to its Charisma-based skill checks. In addition it has advantage on all Charisma-based checks and Charisma-based DC saving throws it imposes.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you increase the target's Charisma by an additional +2 for each slot level 3rd.
