Z4D0

not really, his IA deactivate some helminth abilities so if you use one of them you are forced to use this augment and using normal excalibur like a guy said its not that cool because umbra has some better stats an a way better drip than normal excalibur, besides that, excalibur already need chromatic blade and furious javelin to make two of his abilities good so you just give three slots for some reason, if warrior's rest had better strength you could just gave up some mods for that
