You conjure a beast of sheer force and unrestrained rage. It appears in an unoccupied space of your choice within range and shares your initiative, but takes its turn immediately after yours. It uses the mule stat block, with the following changes:
+It uses your proficiency bonus
+It uses your spellcasting ability modifier for its attack and damage rolls
+It has a speed of 60ft
+It has an amount of hit points equal to the spell's level, and can make an amount of attacks equal to half the spell's level (minimum of one)
+It is hostile to all creatures
At the beginning of each of your turns, you can choose to make an ability check with your spellcasting ability modifier. If you succeed, you can use your bonus action that turn to control the mule. If you fail, or choose not to control it, the mule spends its turn moving towards and attacking the closest creature it sees. The mule disappears if it is reduced to zero hit points or it moves beyond the spell's range. If the mule disappears, you can use a bonus action on subsequent turns to re-summon it.
