Alliterate

You channel your magic into a word you call out in reaction to a hit. You may rearrange the name of the creature you call out changing its form for that hit. The save type can always be a con save  but can also be changed based on the form you are transforming it into. The number failed by decides the size of the creatures form (see the table below. Ex. The save dc is 16 and an attacking cow is hitting you rearrange the letters into Wok and the save can be either con or Charisma due to its association with a performance check the cow rolls a 10 it is a small wok for the one hit dealing 1d8+2 bludgeoning damage. If the target passes the save nothing happens.

This spell's flexibility grows when you reach certain levels: one letter changes to whatever you want, 11th level (2 letters can change), and 17th level (3 letters can change). You cannot add letters but 3 letter words can be anything that is 3 letters ex cow can now be fly becoming a bug.
