Create a spell, with bound "insert item" for 2 seconds on self, and also add this effect to the SAME spell, and soultrap on target. Cast that ONE spell you created. Your item will now be there forever, but you can't drop it. You are able to unequip the item.
Weapon Stat Increase Code
To increase your weapon stat beyond 100, drop all your weapons except one, and summon a bound weapon of the type you want to increase (Bound Longsword for long sword, etc.). Then hold down R and X to switch between your one weapon and the Bound Weapon. Each time you equip the bound weapon, your stat in it will go up by 10. The Fiend Katana, which can be acquired by killing Ra'Talle in Balmora, is ideal for this. Note that if you raise your stat above 100, you'll no longer be able to train in it, and if it's one of your major/minor skills, you won't gain any levels from raising it like this.
