At reboot:
-- your guild item will switch from a bracer to a quiver. This quiver can hold
about 100 arrows or so. Items it holds weigh a lot less, making it easier to
carry a reasonable amount of ammunition.
--- "weapon familiarity" is added. The more times you hit with the same
launcher (bow, sling, etc) the better you get with it. A new archer boon
improves both the rate you become familiar and the effect.
-- your location of weak points data is available in the guild.
-- you can clear your archer boons every week.
