Seriously, this armor combo is ridiculous and not too shabby to look at either since most, if not all the pieces are identical except for coloring. With 3 pieces of Vekreth armor, you get +15% Crit damage, +2 finesse abilities. 2 pieces of Lunala's armor and you get +20% crit. This stacked with the individual crit bonuses for each individual armor piece & having Assassin's Art at 8 for a crit bonus of +70% from Stealth, and this build hits like a ****ing truck.
From what I can tell, yes. I'm 38 hours into the game and FINALLY completed the Vekreth set. If I recall correctly, most were from chests found in the Detyre area. I've maxed Detect Hidden to make sure I don't miss anything.
