I use one now as my primary and horns of discipline on secondary and I must say that the horns are much better in my perspective... Its odd that these are higher attaining lvl that the horns... I may be wrong though, I'm on evry day practically as my bsl Lynxir. Msg me if you hav any advice on these or bsl, etc.
There are better primary weapons for beastlords at lower levels, but you could probably get anywhere from 50pp to 100pp minimum, more if you sell to someone not on luclin. If this weapon was availible on the secondary slot it would be worth more.
