Points
There was no Beast Totem that appeared behind Sylas this time. He didn't have enough Aether left to use it in the first place, but it was never his intention to do so.
Although he had learned how to use his own Aether to speed up his own personal healing factor, it took time and, obviously, Aether. There might not be any breaks at all in this Dungeon, and he was already running low on Aether after his first real battle.
This was to say that there was no way he could afford to waste his high powered <Psychedelic Punch> now, not when he would end up with a useless arm and no Aether to rely on.
So instead, he set up the perfect situation to use the weakened version. This was precisely the version of Psychedelic Punch that relied on Slow and Freeze to work. It was just unfortunate that it dispersed a great deal of his power when it acted.
But…
The result of the punch shocked even Sylas.
