Unkillable Monster - Spoiler

[davfrahen]

I`ve got to the last pool in TOB. I am trying to kill two Mariliths in order to get to Melissan for the last time and nothing I try works. I`ve used everything from Carsymyr 6 to FOA5 and all I get is weapon ineffective.
I even tried time stop and used every weapon I possess with the same result.
Any ideas please?

1.) All you have to do is kill the Fallen Solar. The Mariliths are optional. After you kill her, just trigger the pool.

2.) I think they might have a mantle spell on them, possibly protection from magical weapons, so you can wait until it wears off and bash them to remove their stoneskin, if you really feel like killing them.

"All you have to do is kill the Fallen Solar. The Mariliths are optional. After you kill her, just trigger the pool."

I didn`t realise that. It was strange - I took the level right down to easy and i still couldn`t harm them. I tried non-magical weapons as well.
I went back to hard level and suddenly they started taking damage.
Time to go round again!

Iirc 1 of the spells Mareliths like to cast is protection from magical weapons
try a breach on them. That should take their defence down (iirc they are naturally immune to normal weapons). Check Elminster's book ingame I think they have a description in them.
