concentration, 1 minute/mana
As two actions, your mind splits into two independent parts. You have advantage on Will saving throws and your second mind has an action which it can use to take a purely mental action (such as identifying a plant, herb, concoction, or spell or casting a spell) in the same round you take your normal actions. It has a mana limit of 1 and the mana is removed from your mana.
You can expend 1 additional mana to so the second mind’s mana limit increases to 2.
You can expend 2 additional mana to so the second mind can use two actions.
