So, I built a new paladin today, and put a Chimera's Fang together for it...
And quickly found myself reaching back into my pack for my +3 Scimitar.
So, why exactly does this weapon, which really you shouldn't get ahold of until lvl 7, or even 9, do poorer damage than a vanilla weapon easily found off the AH or in quest? The Dragonmark thing doesn't actually -add- that much to the weapon - parrying, and stacking 25% fortification, at the (minimally) cost of two feats, does not make me want to use the weapon.
So, at level 9 when you can get full use out of the weapon...you're stacking it up against something like Prysuul's Bane, which can punch a fairly common DR...
But wait, that might be unfair...how about a ml 4 Bastard Sword?
Or a ML 6 Bastard Sword with Parrying?
So....really...what gives?
Compared to the Jidz-Tet'ka Bracers and the Blademark's Docent, the other items in Sentinels come off extremely poorly - my monk wore the Jidz-tet'ka from lvl 5 to lvl 20, my Warforged usually wear the docent from lvl 5 to lvl 16 or so...The Chimera's Fang lasted for less than a rank. Midnight's Greetings didn't ever find a home on my Rogue, despite him both having the weapon from level 4 on and being an assassin. Elyd Edge would be situationally useful on my Bard, but she's usually too busy flinging around a Falchion and beating heads in.
