It can, however, be detected by land mines.

As for the SoCMs I generally just use them to change one of my arms to the highest tier material in the cloth category (leather<hardened leather<troll hide<ommel hair etc.) as I can, and then use scrolls of harden material to beef it up from then on.
You could also do the ommel cerumen exploit if you wanted.

I'm confused. So scitalks are only effective for a limited time per monster?
So technically I can only talk to a Mystic Dark Frog X amount of times before he becomes useless, but I can then go and tame another Mystic Dark Frog and get another X amount of beneficial scitalks?

I'm putting it down to being another in-joke by the devs. Speaking of which, who's the guy getting hit with a coke bottle in the graphics files?

I personally have absolutely no problem with exploiting the hell out of everything I can in IVAN. Once I actually win the game I might try to finish it legitimately. My current playthroughs tend to involve artificial limbs, mustard gas, stacked mine traps, sabotaged sumo wrestlers and copious amounts of enchantments stolen from the library.

...why have I never done this?!
Also if we're talking about taking screenshots rather than video, FRAPS has a screenshot tool that just saves screenshots into a folder every time you press the corresponding button. No need to paste into paint or resize either. But that would involve getting FRAPS, if you're not so inclined.

Screen capture software for IVAN?
Well, you could try FRAPS or Camtasia Studio.

Just checked the script. Orcs have infravision, skeletons do not.
Interestingly both have gas immunity, which I wouldn't have guessed for orcs. Xinroch also has added teleport control.

Even worse, necromancers have intrinsic infravision too. So the only things you're likely to fool with invisibility in GC6 are the zombies and kamikaze dwarves.

Oh yeah, might want to take a wand of fireballs or two with you. I believe there's a Veteran Kamikaze Dwarf who always spawns there...
Also, blowing things up really helps clear the hordes. Worst comes to worst, just flee to the exit and hope you come out in a tight hallway where you can zap a wand of striking down the corridor of enemies that followed you.

Hmm? Maybe setting mines inside the sumo arena alerts the town...
There must be a way! *also drops everything to play IVAN*

EDIT: No... Setting traps angers the townsfolk, sadly. HOWEVER you can use teleportation to get outside the arena walls, and vomit everywhere or cover the floor with broken glass. That works just as well. You could also try spilling sulphuric acid everywhere, but breaking any wall results in the town getting pissed off, so that's incredibly difficult if you haven't got a companion to throw things at - and then you might miss and break a wall anyway.

Anyway, if you really wanted to see the spectators blow up you could just script in some big mines in the dungeon.dat file

I am 99% sure you can enter the arena under invisibility. As I recall, you only challenge Huang Ming Pong if he can see you while you're trying to go down the stairs. This way you can also bust open the glass walls and set mines or whatever to kill off the spectators

Maybe you could also lure him outside with food as JoKe said, and then just shut the door on him? Lock it too.
