Hi,
According the rules, if END is reduced to 0, then until recovered future actions requiring END make the character take STUN damage instead.
If a character with a DRAIN END attack causes a target to have their END reduced to 0 but they still have more points left in their DRAIN, does the target then take STUN damage? And if so, is it at the same rate that the character would lose STUN if they had no END, thus 1d6 STUN per 2 END (IIRC)?
Cheers,
Francis
