I'm almost done assigning recharge times to the spells we've found in other sources, but I'm a bit torn over Lesser Vigor from Complete Divine. Basically, it grants fast healing 1 to the subject for 10 rounds +1 round/level (max 15). A second application adds the full duration onto the ongoing spell.
I'm not sure if I should give it the general recharge time (1d6+1 rounds) because I'm a bit worried of it being stacked to hell. Perhaps a recharge of a few minutes, so that it can be used often and for tactical reasons, but can't really be stacked unless the caster extends it or has assistants, like most other pre-battle buffs.
Some input would be much appreciated.
