I took the monk rules you posted from the 2024 preview here:
>>4338

The big thing is that the bonus action doesn't have to be an unarmed strike anymore but can also be a grapple, shove or with lv.2 Monk's Discipline also disengage or dash.

>What about climbing speed? I have 10 for some reason.
Hmm, I dunno. I don't have a dedicated climbing speed like Cat, normal rules should apply. The liquid form is an excellent swimmer but average climber. The viscous form is good at both and the liquid metal form is an excellent climber but bad swimmer.
I don't yet have any monk feats that help with climbing aside from acrobatics so yeah, normal climbing speed. Therefore I propose - normal halved climbing speed - 20ft / quartered 10ft in extra difficult terrain but Acrobatics instead of Athlethics check if required. Dedicated swimming speed 75% - 30ft and 50% - 20ft in difficult situations but normal Athlethics check if required.

>ability score improvement
Oh, almost forgot that, thanks!
Honestly I'm torn about such a strong improvement at lv.2 out of nothing. It's already a lot. I would propose a massive increase with form change available at lv.5 and lv.10 and otherwise only +2 per level.

If so I'd level up DEX from 14 to 16 and thereby to +3 modifier. This also raises my AC to 15. Does my Yukata count as armor now? Then it's actually 16 unless I'm naked (which I strongly prefer)!
