Jigby: Eh, that part is so heavily scripted that I fear tempering with variables in memory might break something. I'm afraid you'll have to power through this one. Just to be sure, the things that need to be done are:
1; on level 2, you have to brew 4 wywern poison potions from 4 wywern stingers.
2; you also have to brew a modified histachi brew, then use it on level 3 to get behind the Unseeying eye or whatever it's called. There you have to press a lever there to lower the bridge in south
3. get pass the bridge and kill Thorasskus, use wywern potions to poison the 4 vats
It's definitely overengineered, I think the guy that designed it also designed the Ice Temple. That said, MAYBE you could just cheat in the wywern poison - have cheat console enabled in the iwd2 config, then ingame open console with CTRL+TAB and enter ctrlaltdelete:createitem("61GENWP"). Do it 4 times. Also, you could MAYBE forego the whole histachi thing and just teleport past the bridge with ctrlaltdelete:enablecheatkeys() and then CTRL+J for teleport. Or you can cheat in the modified histachi brew - ctrlaltdelete:createitem("61POTNSB")
Yup. I ended up cheating the wyvern poison to get to Level 4 which was complicated in a better, interesting way. I'm finally out of the Dragon's Eye totally and on to bigger, better things.
