You need a merely 51 slayer and 45 sailing to go get this weapon. 70 smith to repair and 65 attack to equip it.
It boosts a higher attack accuracy and strength stat opposed to the (imbued with tentacle) whip.
You need 87 slayer for that and 75 attack to wield it.
On top of that you also seem to get defensive bonusses, except against crush.
The only thing is that it attacks 1 tick slower, which does make a difference, haven't ran the calcs but doesn't it come rather close for something that requires so little to obtain.
On top of that it doesn't Degrade or Break as far as i can see?
Don't you think the requirements are a bit low for such a weapon?
I personally think they are.
