Talk:Menticide Nyx Helmet/@comment-93.36.125.115-20130506223136/@comment-8002187-20130523155229

Shield loss on the Menticide is always -5% of total shields, including any shield bonuses from Redirection.

The stamina gain is just a flat boost that doesn't scale after mods in the same way however.

Looked at this way, you likely lose more than you gain by equipping Menticide (depending on how you personally value shield HP vs stamina). But the amounts are low enough in both cases that realistically, the helmet really doesn't change the game in any noticable way.

TL:DR - Use it if you like the way it looks over the standard helmet. It really doesn't add or subtract anything in substantial way besides aesthetic value.
