Not death, its serious maiming which interestingly in real life is consdered nastier by many people... get the difference between cruel and unusual punishment versus execution?
Maiming is closer to identity loss... if your character dies they died being a hero - being themselves hopefully.
And this is the kicker many players see the advancement as a personal accomplishment... the magic user is a worst case scenario since he was so impoverished of wizardness when he started out... that being knocked back to low level is horrible. I take my level one wizard up to level 6 trust me back in the day (AD&D) this took a lot of gaming sessions (this seems to have gone down in recent versions). he gets hit by wights or whatever level draining monster and shunted to a level 1 or similar.
His identity has been stripped and for all intents and purposes... leaving a husk...
This mechanic feels chronically tied to player resentment which is core to the DM versus Players mentality.
The DM has tons of power... this feels like rape.
I don't understand this attitude at all.
A threat is put in front of the party. The party engages or doesn't. The party succeeds in the engagement or doesn't. The party lives with the consequences of their actions. Am I, as DM, not supposed to put challenges in front of the party? Are all challenges to be illusory, with no real threat to the characters? Is it my job as DM to keep the pcs healthy and whole?
I don't, as DM, just start subtracting levels from the pc. First the pc has to get close enough to be hit, then I have to roll a to hit against his AC. I mean it's not like Sanctuary or successful attempt at turning by a cleric or, in many cases, Protection from Evil completely prevents level drain from happening.
If the DM is attacking first level characters with vampires, that's a DM prolem not a system problem. If the DM is railroading the players into a scenario where the only way they can succeed is engaging a level draining creature in melee combat, again, that's a DM problem, not a system problem.
The pcs I dm'ed always ran away from level draining creatures. Therefore, as a mechanic, I thought it did exactly what it was intended to do, and actually worked nicer than, for example, a CoC-esque sanity check where I had to tell the players that their pcs were scared.
Level drain as loss of identity? I just don't get it. Gobtharb the Mighty is level drained from 15th to 1st level. He still saved the princess, defeated the dragon, overthrew the dark lord, and did all the other things that took him from 1st level to 15th in the first place. He still has his friends, retainers, wealth, land holdings, army, magic weapons, and fame.
