Since you would be staking with rune knives, just get higher range and don't level strength at all. You would still get HP but you wouldn't have unnecessary combat levels due to strength.
Hahaha, noobs. ^^
Strength wont effect your combat especially when you get to prime staking levels.
(82 range, 94 hp).
Calculate without att/str and it will say "you can level attack and str levels XXX"
At the above stated levels i think 50 att 80str is possible and will not combat level you.
Use a calculator
