Dense thunder as a skill has a little bit too much Ki cost to be worth it, can the mechanic of Dense thunder having half-ki cost when used at someone's side come back? Crane Hop does not become a huge issue for this anymore because crane hop is 2m

Don't see why not.

6 ki Dense thunder sounds good.

[Lolzytripd]

it seems more like an issue with monk, they need another way to get ki in battle, and that their ki should persist between battles.

serpent strikes could gain +3ki when hitting with a critical strike

and a passive that gives 1-3 ki when an attack misses them.

I believe the ways to gain Ki are fine enough for the most part, although I would be in-support of the OP; this is something I've been ranting about in the woodworks on-and-off since it was changed to a higher flat amount.

Dense Thunder could probably fare with keeping the same Ki Cost as it currently has and gaining the Situational it previously had that allowed half-cost procs of KD from the side (but only the sides, not the back).
