Voodoo doll vs mosqito bow (I'm not sure if I spelled right pls don't judge me)

[Mrchip1212]

Recently I was thinking if I should get one. I'm zombie 3 and spider 2. IK that voodoo will do WAY more dmg BUT I can swap with a fot so mosquito will do 77k or more. Mosquito costs 4.7m and voodoo doll 1.3m. pls consider that I'm low slayer level
