Attuned crystal halberd

The Attuned crystal halberd is a better version of the crystal halberd that requires 80 Attack and 50 Agility to equip. It is made by Crystal Singing at the crystal bowl in the Ithell district of Prifddinas, requiring 90 Smithing and completion of The Eyes of Glouphrie. This turns an attuned crystal weapon seed and 3000 harmonic dust into the attuned halberd, giving 3000 Smithing experience.

With this halberd, you have a small chance of doing 25% extra damage on a hit. This chance varies with your Agility level and maxes out at 12% at 99 Agility. So at most, this gives it a 3% damage boost over the chaotic maul and Chaotic spear, which have identical stats otherwise.

The attuned crystal halberd degrades during use. Each halberd can do up to 2,500 auto-attacks before it degrades to nothing. Note that unlike regular crystal equipment, attuned equipment does not revert to a crystal seed after its charges have been used up. This makes it last for 125 minutes of continuous auto-attacking, but with the use of abilities, auto-attacks are much less common, and the halberd can last for 10 or 20 hours if used properly.

This can be keepsaked.
