Guild Wars 2

Does anybody know what the lore says about Spirit Weapons?
Do they have a mind of their own or are they constructs which are controlled by the guardians mind.

Lore doesn’t seem to specify afaik, but i would say the latter.

First off all be carefull to not mix mechanics up with lore. The spirit weapon is more a game mchanic. But to asnwer you from a lore point of view and looking to gw1. In gw1 there where spirits you could summon wich where also bound to the floor with a chain. Those spirits where the spirits of dead people comming to aid you in your fights. There where also enchanted weapons wich where real (non spirit) entity’s. Like the spirit weapons they had no wielder but they where fighting on their own. So a possible lore answer could be that spirit weapons are the spirits of the nechanted weapons and therefor if they where a rudimentary entity, then so are these. If it fights for you on a free will or are forced to it by the summoning guardian is im afraid unknown.
