Narcus's LV obtained from receiving damage should be halved. Slydria said everything that was in my mind. And don't forget there's no way to dodge a Ghost/Hexer with 1200 HP and 60% DEF/RES using Narcus + Screamer along with Ether Invitation due to Pilfa's Masochism. (Or heck, STR, SKI and LUC are not even needed, so they invest in DEF/RES/VIT and laugh at whatever comes at them.)

The only counterplay in this case is heavily investing in Fire Resistance or using Red Letter, which is kind of... 'bool'. The whole need to use a different equipment just because a specific enemy setup is broken, I mean.

Just a wild brainstorm. Why not make Narcus cap at LV (Scaled STR * 3)? I'm already fine upvoting the -50% from damage received, but making STR matter a bit for Narcus could be a nice alternative.
