Elven magic user sure like Banishment.
While trying to explore the Elven Halls a bit early (my Paladin was at level 13) i have encountered in the 1st level an Elf that apparently favorite spell was Banishment.
I saw it and immediately ran to stick my newly acquired very nice fire sword in his skull, but just when i was near, he shot me with a Banishment.
With luck i found the Abyss exit rather quickly, then once back into the Elven Halls, met another Elf unless it was the same but the result was ... Banishment immediately.
Less luck this time with a few bad mutations gained thanks to the demons running after me, but managed to exit the Abyss again without too much time wasted in it.
Back into the Elven Halls, found another similar elf, i could have ran away, but i wanted to see if this one had a different kind of magic spell interest.
Wrong . Banishment that is all.
This time it was very bad, the Paladin was really badly mutated from every side and i escaped death i can't even understand how at several point of my long (couldn't find an exit for way too much time) Abyss exploration as there was some really ugly demons around, died dozen of time (save scummed as i wanted to see if the Paladin could find that damned exit) and finally after i can't tell how much turns, the exit.
Saw an insane amount of time the Logunu altar, i guess the game wanted me to convert to have a chance of escaping, as the exit was nowhere to be found for way too much time.
Was surprised to not have seen the Abyss rune, as i am sure the Paladin spent enough time for it to spawn.
Back into the Elven Halls, but in a very bad shape especially with all those horrible mutations (teleportisis 3, herbivore 2, deformed body 2, blurry vision 3) no more potions (everything used in the Abyss) and the Paladin was killed soon after by some elf shooting electric arrows.
As at this point of mutation the Paladin was not really playable anymore and i let him rest there.
