Stopped my testing with Crimson Skillchompas at 33 minutes cause I gtg
My results though are 137k xp and 1200 used with voice of seren, mining outfit, t3 aura and lava titan.
Assuming the average keeps true for a full hour using all of that is about 250k xp/hr with just under 2.2k Skillchompas used at about 2.4k each for 21.1gp/xp
Use brings about wear, tear and rust, and that's a real waste.
It's not the end that I fear with each breath, it's life that scares me to death
