Questions regarding firekeeper souls.

[Gaming Gamer]

Do they respawn on ng+? i plan on killing all firekeeper towards the end to get to +6 but i don't really want the firelink shrine bonfire to stay unlit for the rest of my ng cycle. do the firekeeper souls that are considered treasures respawn in ng? like the one in new londo or do you only have 1 chance to get your estus to +7 once per save file?

They do respawn in NG+, so if you want to kill all the firekeepers, you'll be fine. If you want to wait until NG+ to max out your Estus Flask, that's fine, too.

Firekeeper souls respawn on NG+ , like all other items.
And killed NPCs will respawn too.

Thanks for the answers. i though that all fire keeper souls that are counted as treasures would get replaced
