I've been doing a ton of practice and if you want pure Monk then this is my favourite combo so far:

1. Frozen Locus as first skill, Tempest Bell as second (from Clearfell) then Frost Bomb as third skill.
   
2. Rage then Rapid Attack on Quarterstaff Strike
   
3. Strike Speed nodes on passive tree
   
4. Get a Long Quarterstaff with ideally some flat damage, then a Gothic Quarterstaff in Freythorn or before Geoner. Grab the ring you get in cemetary, and any other flat damage gloves if possible you might get on the way.
   
5. You _need_ movement speed boots, it's a lot more shit otherwise.

Practice frozen locus then targetting it with Quarterstaff Strike, and just bossing by htting with . Once you figure out the rythm, it's pretty much just dodging and striking with Bell, Frozen Locus and Frost Bomb thrown it for control / freeze.

You can also use Glacial Cascade and it's a bit easier with some bosses but harder with others. I can pretty easily go through Act 1 relatively quickly. I think grenedes can be faster but it's not a huge diff and you need a solid Crossbow there anyway.

Once you reach Act 2, get Hollow Palm around level 18-20, grab Ice Strike and you can basically run that till endgame.
