Do the cloned characters on the Shadow King boss node of global hero stay at their current level and power or do they increase with your level?

Unfortunately I can't check myself, but does anybody know if the cloned characters on the Shadow King boss node of global hero stay at their current level and power, or if you increase your characters to level 110 do the cloned characters also increase to level 110?

I ask because five additional levels might change the composition of the characters you need to bring to global hero. For example, if OML stays at his current power level, even if your Logan is 110, maybe your level 110 characters are more likely to survive his onslaught and still win. We might be moving away from requiring either Liberty or Brimstone to finish.

Anyway, anybody know or able to log in and quickly check?
