Cleared Tower of Trials Floor 100 Today.

I heard about a Trial Tower that resets periodically, similar to the Abyss content? So I pushed through to floor 100, only to find there's more above it. It seems like you need to understand the system a bit to make the Trial Tower worthwhile. Performance-wise, Yoongeon and Freya seem better, but Theo and Seollan have their own charm. I just set that party to auto-proceed to the next floor and left it idle. Hmm, it feels like the game is getting harder and there's more to learn... ;
