Minion Template (CR +0 or -1)
CR: For creatures with a CR of 1 or less, this is the same as the base creature, though XP is reduced by 50. For creatures with a CR of 2 or more, this is the same as that of the base creature –1.
Delicate: A Minion does not add its Constitution score to its hit points (or its Charisma in the case of an undead creature; or bonus hit points based on size in the case of a construct).
Special: All animals and vermin size Small or smaller with a CR less than 1 automatically gain the Minion template unless they are animal companions (or equivalent.)
