i have just completed the game
first let me excuse if i post something that was mentioned before because i have not the time to read through this all
i had a litte bit easyer time beating the game because of a few bugs
and it was also a lot of fun and caos
the most helping bug i think was the dismissal bug
it makes the dc for dismissal on very powerful enemys exactly so high that it may work
i have used it to "dimiss" (kill) iuz and zuggothmy and the dc was in both cases in the 50s
the most used an generally helpfull bug was the one with haste
(and the most known i think)
just cast(all the uses) haste on one char and it will transform him into a killingmachine
or if it is not enough cast it a secound or third time
and the most caotic and fun bug was the one with the golden orb (i think it is a bug)
i could summone just any number of l earth elementals
...
so i filled the room with the old women with 5-10 earth elementals
they attacked after a short time (just another bug i think)
so i hit the old women with my invisible rouge to transform her into zuggi
the she summoned 3 vrocks
i summoned a few other demons and more elementals
its total caos a brawls of demos zuggi and elementals so i managed to sneake my rouge out
...
meddle a little bit with the brawling mob for fun
...
and sneak my cleric in to cast dismissal
...
watch the end sequence
sorry for bad spelling
and hopefully a new bug was found
i had v1.0
perhaps i will play it again when the patch has a final version...
