you need form 2 of gen 2 ten tails and raion barrage or bruce dragon combo.
in the video im using bruce dragon combo.
to do the glitch first enter the 2nd mode of ten tails gen 2 and then use raion barrage/BDC on a log or a player, then as soon as you in the air spam the Z spec and you should get inf ten tails.
(be warned after you do this your character will be broken and you need to reset to fix it)
