Contentious Plan

You may touch an number of creatures as part of casting this spell, but you must touch at least three creatures (this may include yourself). Each creature touched must draw up a plan of action on their sheet of paper using one of the vials of ink. Then, the creature touched must choose a particular kind of ability check, such as Dexterity (stealth), or Strength (Athletics) and come to a consensus on that check. When they do, the spell is completed and for the duration of the spell, all creatures who were touched gain advantage on that ability check.
