I wanted to make a 10 Div challenge build for quite a while. I actually have never done a build from completly Zero before so I started looking for build Ideas. Since I had a decently level Templar I was looking for builds that could abuse the Relic passive from Guardian. Lightpoacher looked really interesting with the Tri Elemental stacking so I decided on an Abyss stacker. I read on the Wiki that you can prevent the Spirit Burst from casting by having less life than the cost from Archmage+Lifetap so I decided to go CI which also works really well with Guardian. Since my Damage is trash without Spirit Charges I really do want to keep them as high as possible for as long as possible to make anything like Elderslayers feasable.

With the 10 Div I had available the only physical Spell that seemed viable was BV since you dont need any extra stats like cast speed.

In the end I would say the build performs pretty well for the budget, it has satisfying screenclear, decent damage, is pretty tanky with max block and spell block and a decently chunky life pool.

I do not think Guardian is the best Ascendancy though. Probably would work better with pretty much any other ascendancy out there. The Sentinel sucks without investment in Minion life or res and dies pretty much instantly and is very annoying to recast constantly. The block chance is pretty nice and works well with the build. The Relics have decent up time but the only really useful aura is Hatred.
