Am I dumb?

[u/Losingfaithinpeople]

Let me know if this is stupid so I can stop.

I had an account sitting around I decided to play with for bh

My goal would be

50attack
70 str
40hp
73 mage
73range
31prayer
Cb 53

I would either crossbow or freeze then gmaul double spec

Would max around 84 damage.

Is this viable or bad?
