With this bow, you have a 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 zaryte bow, which has identical stats otherwise (except that this bow lacks the +2 prayer bonus of the zaryte bow). This weapon can be stored using a keepsake key, but only when newly made/repaired - used versions will need to be repaired first.
