Powerfrog

I find choosing between strength (+10 strength) and glory (+6 str, +10 accuracy) difficult. Sacrifice +4 strength for +10 accuracy? Probably not. Zerk ring (+8 str) vs Onyx ring (+6 accuracy) is a no brainer for me. Sacrifice +8 strength for +6 accuracy? Hell no. To be fair, i just wear ferocious ring 24/7 when slaying :D

Rapier is certainly capable of handing every single task, but as you should know, it's not the 'best weapon' for every task. If you have a maul for waterfiends, use it. If you have high magic or range levels i'd recommend them for tasks such as mithril dragons. I have both rapier and maul and maul is honestly only slighty better for waterfiends. Sure it's a lot more accurate, but in terms of damage/time rapier is pretty close as when it does hit it does great damage and attacks so much faster.
