At 400 dark magic skill and with no Aspir-enhancing equipment/traits, unresisted Aspir II appears to have a maximum of 240 MP (actually observed maximum: 238 MP) and minimum of 120 MP (actually observed minimum: 121 MP).
Consistent with previous results, the variability of MP drained with Aspir II is higher than that with Aspir I, which appears to be a result of the range of possible values increasing as the maximum increases. (The maximum of Aspir II, for a given level of dark magic skill, is higher than that of Aspir I.)
