You are able to use your arcane bonded weapon to store a spell as with a spell storing weapon.
Benefit: You are able to use your arcane bonded weapon as a spell storing weapon. If the weapon is normally a spell storing weapon or becomes enchanted as such, you can store two spells in it at a time and choose which spell to cast when you successfully strike and damage a creature with it. You can only cast one stored spell from the same weapon per day: the other spell remains stored but cannot be used until the next day.
