First, if you dig around you will find that on MULTIPLE OCCASIONS I have advocated that a WILL save is much more appropriate than Fort saves. The idea of a FORT save in this case is certainly the implication of the effect being encountered and overcome.
THAT SUCKS. I agree with you that *specifically* using a FORT save and then describing a character overcoming the look is every bit as wrong as any other option I've complained about. If I advocated THAT I'd be dead in the water.
Hmm, fair enough then.
Though I'd say Reflex (looking away in time) is also a good pick.
What about some of the suggestions from the other thread, though? Like doing an attack with the medusa and if the PC is hit/included, they can choose to either be blind for a round (ie, closed their eyes) or petrified? Since that does sidestep both the myth problem and the save or die aspect.
Still, it seems that the Medusa has some special place for you - particularly odd since it's an unremarkable monster in D&D. Do Banshees automatically kill anyone who hear them, to match their real world mythology? Cause it's a lot harder to avoid _hearing_.
...
Another interesting compromise position might involve Stakes - so the PC might choose to take a risk, upping the stakes (for some benefit), but doing so leaves them Vulnerable. And PCs who are Vulnerable can die on a failed save.
Or come at it from the other direction: if it's just a question of lethality, is there anything wrong with lots of attacks that can be equally lethal? Ie, if you have a 25% chance in general to die from a finger of death, why not from a greataxe hit (or crit)? Where's the line in the sand where it's cool for a poison to instantly kill someone, but an executioner's axe can't?
After all, the compromise might be to simply flip a lethality bit and suddenly _lots_ of things become more lethal. Maybe it's just 5th or higher level spells, some monster abilities... and any crit from a 9th+ level rogue/fighter/etc, to restore parity. Or maybe the non-caster classes get their selection of daily "quivering palm" examples. Rogues get assassin strike, etc.
