Death ward protection vs Characteristic loss

Question

Does DeathWard protect the objective against characteristic loss, consequence of... I don't know.... Venom? Necromantic spells, or any other form of Wis/Con/Dex, etc loss?

Answer 1

Short answer is No

From the description of the spell:

The subject is immune to all death spells, magical death effects, energy drain, and any negative energy effects.

This spell doesn’t remove negative levels that the subject has already gained, nor does it affect the saving throw necessary 24 hours after gaining a negative level.

Death ward does not protect against other sorts of attacks even if those attacks might be lethal.

Okay, so in order to be protected the effect has to either

1. Have the [death] descriptor
2. Be a magical death Effect
3. Cause energy drain (usually negative levels)
4. Be a negative energy effect

So, from your examples,

1. Venom - Nope, not at all.
2. Necromancy Spells - Not usually, unless it meets one of the 4 above
3. Other - Nope, unless it meets one of the 4 above.
