Let's talk about the update 11 raid

[Scraap]

Weeeeel... If they're sticking with aberrations, the unholy spawn of a rust monster and a beholder could be fun as an add.
Make wit de magic, it turns and cuts that off.
Slap it around too much, time for a new set of weapons.
That'd give something for ranged and monks to play with. Wouldn't make it the only boss though. (or even necessarily a boss).

If they want to emphasize skill usage a bit, one each of a recruit-able intim, diplo, and bluff 'miniboss' for holding off waves of attackers.

If they want to reflect the effort of two toons working together, a bridge that can be blown up using a high level place-able trap that cuts off respawns.

Stat damage and penalties... would be great, if the code reflected the description, and penalties weren't cleared with one mass heal alongside damage, but that is likely a topic all on it's own...

I forget the name of the quest, but there's one that brings all magical effects down to half for the damage both divine and arcane on weapons and spells... One of the necro 3s...
