I’ve made a Sage Chrono Kino and honestly it works, but it’s a bit on the weak side. Sage isn’t as bad as you’d think, the problem is mostly Kino not delivering enough.
This is my build: https://tos.neet.tv/skill-planner#21e84.154585.113d4f91aab5.2d314f618a75.355f8a6a75
If you ever get a Boruta seal you might want to consider dropping teleport entirely for lethargy and just keeping 1 in Blink for memes. Teleport is honestly a piece of ■■■■ skill anyway and is never useful for anything except skipping barriers and exploration.
I also have a video of it soloing CM Stage 5: https://www.youtube.com/watch?v=PujcdkvnQSE
Basically you have two combos.
Heavy Gravity -> Energy Bolt -> Magic Missile -> Energy Bolt (Yes, Energy Bolt. It does good damage considering its cooldown.)
Magnetic Force -> Ultimate Dimension -> Micro Dimension x3
Then after you’ve used both combos you press Hole of Darkness or channel Gravity Pole for the full duration and then repeat the whole thing. And make sure to keep Enchant Slow up.
You don’t really have that much benefit from Chronomancer yourself except for quick cast for Dimension Compression (4000% SFR or so every 15 sec vs bosses), but you can just keep it on party Pass and use it supportingly. Reincarnate is also always a really nice skill since you can just kill yourself instead of using hp potions.
But yeah, for bossing?? Can’t QUITE recommend it. But it’s doable.
