Why are liches immune to sumbeam?

[Chette]

Level 7 druid spell.
Deals 1d3 + 3 light damage per caster level.
Double damage against undead.

Works great against mummies, zombies, wights, etc. However, liches are completely immune. Made Wizard King a bit annoying until I realized Wall of Fire was a level 5 spell for druids.

Is there some reason that I'm missing as to why a Lich would be immune to this perfect undead killing spell?

Because they're horrible at math?

(sorry)

Always thought that immunity was strange.

I would hope that is a bug. If I ran across this, I would most definately report it as such.

Well, there is this from the wiki on Mantel of Invulnerability, which all liches have:

Description:
While this effect is active, all spells that are spell level four and below are negated.
Note: Due to how it is coded sometimes negates other higher level spells (such as Sunburst, as the blindness component is tagged as a 2nd level spell source, and Greater Shout.)

I dont know if its still true.

Thanks for the info, that is likely the cause.
I will still bug report, just in case
