I'm not sure so let me ask. Is that a normal vorpal of 1000 HP or less? if so it sucks.
You have 4 different tiers of vorpals on weapons all the way up to 3000 hp kills. 2 tiers can be found on random items and yet the MASTERS of vorpal strikes only get the lowest version? So to upgrade your ability you have to equip the same item a non assassin can use with the same effects?
If I can vorpal BETTER with a random gen item than I can with the abilities of a pure rogue assassins own skills then why bother with enhancements? Again, it looks like a change with no thought spent on the matter.
But hey, I might be wrong.
The video presentation never clarified it as if it didn't even matter.
Drow smoke goggles are the equal to being an assassin with lethality on any weapon. Not a good look.
