Level 99 MoM Crit Ice Spear Hierophant^3.27

Notes

If you want to see the mapping dps just uncheck Ice Spear in the skills menu and check Freezing Pulse. Also if you have better gear than me and can afford to lose the 15% all res, just swap bandit from Alira to Kraityn to get more movement speed.
Or you can use Eramir if you want the 1 skill point, completely up to you.

If you aren't farming uber bosses, you can actually skip the Legion Jewel entirely and instead use a Sublime Vision with a high % effect of Haste Aura roll on it instead. This makes you quite faster in maps or content like Heist. This jewel's price may
vary a lot in different leagues, currently in 3.27 Keepers of the Flame its 80 divs so for me that's not worth it to buy it.
And it also means your tattoos in the radius around where the Legion jewel was now work again, so you have full curse immunity without needing a single "% reduced effect of curses on you" mod on any rare jewel, making it much easier to get the
stats you want on your rare jewels since at that point the only good stats for a rare jewel are: % life,resists(until you're capped),any crit multi for cold,spells, or just global crit multi. Also using a Sublime Vision saves you 1 skill point, or it just means you
need 1 less level to get all the important nodes since you can unspec the keystone which used to be transformed by the legion jewel. But obviously its ideal to hit lvl100, which I've done from Sanctum twice now.

If you have enough resists on gear to be res capped with the staff on, can swap Alira bandit to Eramir for +1 skill point so that you only need lvl98 for all the nodes, or Kraityn for more movement speed.

Awakened gems got deleted in 3.28, we got new Exceptional Supports instead. No clue if they're any good, will have to try them out myself. But even without any of them, the build's dps is still insane.
