This was a skill suggestion by Hung, forget the name for the moment and consider the idea.

So here's another suggestion. Add prime monk spell 'Five Fingers of Death'. It costs 100 mana and lasts for 1 tick, so it's unlikely to be used in groups. It makes hands glow red and adds, say, 15(maybe 10 for non-avatar, 15 for avatar) damage for each attack.
The suggestion got lost in the weeds of a different discussion so I'm putting it back up here. This is not a debate about where monk stands in relation to other classes, forget about it for a moment please.
The question I ask is should monks be able to divert mana into their damage?
The answer I come to is yes, that is really a cool concept. It creates a nice dichotomy between the thief class and it's brother class monk. Thief diverts movement into damage via the circle skill like a blast. Then monk is diverting mana, which makes sense in a fantasy reality way and in a mechanics way.
The first argument I see against this is: aren't you turning monks into mage's then? Not at all because the damage is being diverted thru the characters melee attacks. This means that the characters number of attacks and hitroll and opponent AC all play into it. And it also means that the damage being done is slow cumulative bonus rather than the mages large instant damage.
Another reason this would not be OP is because we could take the opportunity to fix some features i.e. nerf down the number of actions that monk can do while deathgripping. This would be a very nice bone to give in exchange for a necessary nerf.
So anyway I thought his idea deserved a second look. I don't care for the name and didn't examine the exact numbers he presented. But I think the concept is perfect for monk prime and it could be balance out easy enough.
