this is just an example of what for me are specialized weapons. The above knife is only effective if you happen to land a sneak attack critical which sums up to more than 200 damage (calculated with perks, sneak attack critical which is 2x crit damage, etc...) which is mostly an instant kill for most creatures out there...
That knife suits my combat style perfectly, since I'm a sneak/sniper character and in interiors I tend to use melee weapons to sneak behind an enemy and stab it/him/her, so I made a mod for myself which is a knife with these same stats.
and now, I wanna know how your fighting style is and how would be the perfect weapon for your style, and call it you "specialized" weapon, since I'm planning on making a mod featuring special weapons that only "works" in one way and I'm really open to suggestions.
Oh maybe this should go to mods section whatsoever, but I don't have it very clear...
