Wanted to celebrate my first Mageblood by making a build to get my first 7/7 Ubers as well.

Why Assassin?
Because the splash art was cool. Trickster would be a better ascendancy for tankiness, but I was able to easily cap crit and be crit immune due to Assassin Elusive. I copied the other Assassins using Replica Covenant but wanted to take it as far as I could while maintaining tankiness. Most KB Frag Assassins on Ninja went hybrid life/es, and took Soul Drinker using FF jewels with the idea of instant leeching both life and ES using a Watcher's Eye and the passive tree for insane recovery, ES overleech being there for comfiness and a little buff (Polymath would be better for raw damage). I added the Rage tech with the Charm and Redblade Banner on weapon swap for an accessible source of burst damage.
Why Herald of Ice?
Because shatters are cool. It adds only a minimal amount of DPS, but helps a lot with clear since I only have 1 pierce on the build. Changing the build to fit Hatred using the Dark Marionette Guardian's Blessing tech would be a lot better.
PoB Link
Actual EHP is 75k without buffs up, but in my experience, it feels very tanky due to high evasion + Wind Dancer and the combination of spell suppression and block.
Could still min-max the build more (better charms, re-rolling prefixes on gloves, a 6-mod wand etc.) but will focus on challenges now to finish off the league. Total cost is just under 400 divines, but has hundreds of divines worth of upgrades still.
Overall, not that much different from other builds, and I sacrificed a lot of damage for aesthetic factors, but I was able to comfortably do Ubers with the occasional death (mostly my own fault). Thanks Affliction for the affordable Mageblood!
