Yea rangers should get criticized for rolling for 185+ spears.Those are certainly impressive stats. I count about 6.5k attack based on his gear, so with a combo I can see how it would be 9k.
I would subtract 500 ish attack, and 130 ish damage for stead aim though. In order to cast it, he would have to switch to a bow, cast steady aim, then switch back to spear. Maybe this is what he does, but it still costs a good auto or two.
I can't say I approve of wasting a shadow spear. (if he owns it, and isnt just borrowing it) Maybe he doesnt owe anything to his clan, or however he teams with other players to defeat mord/hurng, but a spear like that would be in much better hands with a rouge, or maybe even a warrior.
If your world kills mordris with ease, there will be more spears in banks and not being used so maybe thats the story here.
