We have this "one hit killing black mages" in mv. They are insane hard for melee.

Black mages derive from arch seether and are defined there with 90% pierce 10% channeling.
I checked spawnpool definitions at running time, where they have still this 10% channeling.
When checking the spawned mob, this value has changed to 5% somehow. 

The big surprise at the end was, when i looked in attack.c HitPlayerAttacktype(). 

case ATNR_CHANNELLING:
...
 dam = hitter->stats.sp; // use mana to directly damage

So the damage for channeling attacks comes not from damage value and the %channeling, it comes from npc mana. I think "not all" mapmaper know this, to say this more diplomatic.

We want keep this damage calculation for channeling? 

If the mages channel their mana to this one strike, we should add at least add a logic, where these mages go down in manapool. If not they hit again and again this hard? Could also be interesting to give players the chance, that they lure the mages first, to drain some mana, before going close?

Edit: Ok could be interesting for players too, building channeling ma builds.

Edit: At some point we should also add more effects then, like fire damage adding damage over time, where cold slowing down ...
