For most of my game, I was going for two items. The Dragonslayer spear from Ornstein & the Darkmoon bow from Gwyndolin.
I finally aquire both weapons.. only to realise that a normal spear(not even upgraded) out-damages the dragonslayer spear once its fully upgraded.. and the same goes for the darkmoon bow.
The spear is suppose to do 135 physical & what, 90 lightning? very low stats for a fully upgraded boss weapon. Even with both of the scaling stats maxed, its still a very bad weapon. Boss weapons should do way more damage then a regular.. not upgraded version of a spear.
Then the darkmoon bow, I was using a composite bow at +15. Good scaling and everything. then I downed Gwyndolin and told myself I'd get my darkmoon bow. upgraded, it goes to 120 physical and 120 magic. 10 less physical than the composite but you get 120 magic. My composite would hit enemies for 300-400. Yet the most I can hit people for with this is 65? It's just a big dissapointment overall. Turns out theres no boss weapon worth getting in the game. I downgraded the darkmoon bow to a composite, took the hit on spending points in faith just for it, re-upgraded to +15.. as for the spear, I just use my Gravelord sword instead.
