BEAST OF THE NIGHT X CELESTIAL BLADE X BLOOD MONARCH X HERO(???)

[New effect: (Synergy) [active] allows user to synergize all divine authority to evoke new active authority {Hero's will}]

'Wtf is this?'

Upgrade? Synergy? and a new Authority upon activation? What the hell is going on? I've never heard of authorities getting upgraded, can authorities even be upgraded in the first place?

'Sis!'

'Yes?'

'Can authorities be upgraded?'

'Under the right circumstances, Yes'

'Really? Then why haven't you guys upgraded mine?'

'The authorities we blessed you with are already within the highest level any more than that would result in your death'

'Is that so what about synergy then? Can I synergize all of my authorities?'

'YES!' sis said excitedly.

'So, I can?'

'What no!'

'Which is it?'

'I wasn't talking to you'

'Huh?'

'Hey you clearly cheated!!!'

'Sorry?'
