I think this was my first Armataur ever; certainly my first non-Minotaur in months. Finding an artifact crystal plate mail helped a lot (though it did make my Stealth training feel rather wasted).

Congrats! If the stealth helped you survive to get the +11 Crystal in V:5 it doesn’t seem wasted to me.
Fair point; yes, the combination of a few pips of stealth and early lightning scales made it pretty easy to avoid fights I wasn’t ready for.
