Recovers HP and SP every 10 seconds while sitting (not while standing). Recovery is every 20 seconds when overweight and it works even when recuperating from Asura Strike, but without the natural recuperation bonuses
(e.g. at LV 2 you will only regenerate at +8/+4 per 10 sec after an Asura Strike, regardless of INT and VIT).
Base HP recovery is 4 HP per SkillLV, modified by Maximum HP/500. Base SP recovery is 2 SP per SkillLV modified by Maximum SP/100.

Restores additional HP and SP every 10 sec while sitting.
If caster's carried weight is over 50% of the maximum capacity, this extra HP and SP is recovered every 20 sec.
