When you switch back and take 10 shots it will degrade...doh? Nope, here it is straight from RuneHQ Full Charge Exploit For the moment, theres a way to always have a Crystal Bow or Shield at Full Charge (10/10). It was confirmed through Jagex Customer Support that this is a legal exploit, but that it may be fixed in the future. Just as the Ring of Forging has the 140 smelting times attached to your character and not the ring, so to is the decay of the bow and shield attached to your character. The count is 250, use the shield or bow 250 times and it decays one state (ex: from 5/10 to 4/10). Here's the exploit then. Buy 2 or more crystal bows (either from Islwyn or a buy a crystal seed from another player to recharge). Use a Bow till its 9/10, well call this the Decay Bow. Now switch to your other Full Charge Bow that we'll call the Full Bow. Use it for about 240 times (couple of ways to track this). Switch to the decay bow. Use it till it decays which happens quickly. Switch back to the Full Bow to use again for 240 times. Once your decay bow becomes a seed, recharge it in order to use this exploit again. So, you'll still be paying for all your shots. Benefit is you get to use a +100 Range, 25% Max Damage bow for almost all your 2500 shots. The shield has a separate decay count from the bow.
