A LV 100 Pokemon uses Substitute. A FEAR Pokemon that has 1 HP from the opposing side uses Endeavor. What will happen? Will the Sub get one HP? Will the Pokemon get 1 HP? If the Pokemon gets 1 HP, will the Substitute break?
Tested with Hex, and it indeed Breaks the Substitute. This is based on the the HP used to make the Substitute, and because of that, it will not live with 1 HP.
It breaks the sub.
