Could it be possible to add an option for unpain: empower (or so). When
casting unpain at yourself with empower option you could get less hpmax
(50-75% hp boost of current), but the hp boost from the spell would last
longer when taking dam. This would be a really nice upgrade for good relig
tanks, but of course mastery of assistance, guild age and way of the tarmalen
would be affecting factors.

Except that good-religious tanks (at least self-healing monks) get pretty much
no increase in 'way of the tarmalen' because you don't get guild rep from
healing yourself. I think I've clocked 1% increase in 'way of the tarmalen' in
80million exp as a monk tarm.
