Feel free to wayback these... it never changed from unresistable:
Lifetap:

Harm Touch

- "Harmtouch" is now resisted as if it were a "Lifetap" spell, meaning
that it is all-or-nothing, and nearly unresistable with exception to
encounters that are immune to magic or out of the acceptable level
range. In addition, maximum damage for Harmtouch has been increased
starting at 40th level.
I know this was an intentional custom change, made a decade ago on p99, to combat people using ivandyr hoops for trak/raids. It's no longer applicable and should be reverted. This is a pretty bad nerf to necros and shadowknights.
