Attribute Stacking as a Pathfinder?

https://pobb.in/_4nprLC4I7EN

So I wanted to speed level a pathfinder for support drinker with a Pillar build, but people stopped playing and I started really enjoying playing monk skills.

I don't got the budget for anything like an astramentis but I was able to grab a cheap HoWA and other uniques.

Clear feels great, bossing is a bit of a gamble since defenses is basically all Grim Feast. Defenses in general seems a bit scuffed.

Depending hard on a mana flask for tempest flurry spam sustain and some flask nodes to try to make that a bit easier.

Not totally sure if the last ascendancy should be flask charges or a concoction to debuff?

Looking for ways to improve defense, and potentially bossing, Or should I settle for being kinda a glass cannon and lean into damage?
