Before we begin:
This is not a thread discussing whether Death Penalties need to be greater or lesser, or anything else. This is a discussion (using math) to show whether Death Penalties are or are not meaningful to a level 30 player.
Let's look at the total penalties from 5 rapid deaths:
Saves vs Fear are fairly meaningless, so I'm just looking at the neg levels.
5*(-2 Abilities, Attack Rolls, Saves, Skill Checks, -1 Effective Level)
So:
-15 Attack rolls (10 neg levels, 5 from stats)
- Don't know how significant this is.
-10 Every Stat
- This is -5 Damage per Hit, which is not much.
- Is also -150 HP, which is significant sometimes.
- Also is -5 DCs, which hurts.
To lazy to calculate spell point losses, probably around 100?
-10 Saves
- Might be significant depending on build.
-10 Skills
- Only really an issue for UMD.
-5 Effective levels
- Could be kind of painful for spellcasters, not by much though. DCs (might) take a hit though.
- If this effects how much HP each point of Con gives, this would be -5*ConMod HP, which could be significant (100 wtith 50 Con)
So all together, this is maybe -250 HP.
Most characters at level 30 have at least 1000 hit points, so this is 25% of someone's hit points. This does hurt. But not a ton. Especially for a build which tries not to get hit.
This is really the only part of the death penalties that really matters, although the Saves and DCs might hurt certain builds.
