Delivering items requested by the hamlet militia quartermaster, or any materia-enhanced weapon or piece of gear, will not only contribute to the hamlet’s supply rating, but will also earn you an anima boost based on the type of item donated.

Anima was made specifically to benefit people that don't play a lot.

Atm the regen is too low, seeing as we get 1 non-favoured full distance tele worth of anima per day, I think 12 would be fine provided:

SE add some content that lets us regen anima, I am hoping hamlet defence is going to work something like Campaign did, if theyt have it reward anima at the end of each battle (screw the lore). This way we can actually have some way of regaining anima after a quest zerging session, whilst also doing something worthwhile at the same time.
Anyhow, now we can do hamlet defence to replenish our anima yay.
