No you weren't being captain obvious, to be honest I only ever level disarm traps up to get the trapmaker's spectacles so I wasn't aware that poison traps yielded normal poison, well done!
Heh, me neither. Before I started with the game, I read on this forum that traps weren't lethal enough and thus simply not worthy to be disarmed. I probably hadn't noticed this myself if I hadn't tried the skill with a cheated character. Two more of those potions though? Hmm. Could you give away a hint about their whereabouts?
About those spectacles, though. With some fiddling, they can be stolen from the trapmaster in Caladon in the vanilla game. I shall check if it works in UAP as well.
EDIT: Try planting a helmet/head gear on the trap master that is considered better than the spectacles. Or simply cast Body of Fire on him and they should appear in his inventory.
Though it may not seem like it, I have been attempting your targets Deman but have had no success. I tried completing Lukan's and Owens' quests at the same time by getting the thieves' quest first, then Owens', then killing the thieves indirectly so they'd still like me upon resurrection, then completing Owens' quest - but Lukan's quest automatically fails upon his death even if you resurrect him. If you destroy the bridge materials before talking to Owens' he won't talk to you even if you've killed the thieves. I can't see anyway to solve this myself so maybe someone else will have more luck!
I believe I'll post how it's done, it has been Christmas after all ^^. Maybe the solution can be used as guidance on how to complete some of my other targets.
1. First off, you were right about killing the thieves indirectly. Do this, before talking to any of the parties. Revive them afterward.
2. Now, have Lukas mention
the quest (so that it'll be written in black in your journal) to destroy the bridge materials.
3. Walk over to Owens and tell him that you've taken care of the thieves to complete his quest. Note you must not
have accepted the quest in beforehand.
4. Go and destroy the bridge materials and return to Lukas. Ask him about his task again and then say that you've already destroyed the materials to complete his quest.
5. Afterward you should also be able to persuade him and his cronies to leave. It seems that this part was actually easier to accomplish in the UAP.
There you go
. As for the target concerning whacking someone with those two awesome swords in Arcanum; I will reveal the least "obvious" person who can help you with that, namely priestess Birgit in Still Water.
