Prism xp farm

[Decathox]

What are your tips for xp farming prisms ?

It takes a lot of RNG to get the desired perks and a lot of rerolls, and finishing the campaign way too many times wasn't enough obviously.
I'm doing hatchery speedruns sub 1min but it's not that efficient.

Boss rush it. Matter of fact, I was about to head in to finish my explodee prism. Happy to have some company, if you're down. Just so ya know, I'm still waking up.

the by far best is boss rush. has to be either trial by fire or gauntlet as the triple doesnt give close as much XP but difficulty just the one you can clear reliably and at a good speed. a gauntlet is 150K XP as base value on lowest difficulty and a prism can be between 1.1-1.4 million XP usually.

(that mostly depends on how well you keep the level low while creating fusions. the lower your level as long as possible, the less XP you waste)

BR, I keep doing apoc gauntlet for the excitement, but gauntlet on lower difficulties are perfectly suitable for farming EXP to level from 1 to 50, just find the best suit for you.
You can change to the prism you want to upgrade after fighting level 19 and equip a ring, drink a concoction for +25% multiplicative EXP gain. Also you can cleanse your trait points for another 15% on the scholar trait (even though I never managed to do it in time).
If you worry about dying in the middle and not having the chance to change prisms, having a Thaen fruit on you greatly helps. Once you lose it, you can do everything above and just liquid escape to secure your gain.
For legendaries, each roll require 50000 EXP. I personally liked playing 4 levels on apoc gauntlet, then suicide as above. With +25% EXP that gives you exactly 50000.
