That's odd, in GBC it's showing as greyed out for me. But I just started messing with GBC, so might be looking at it wrong.

One effect is his flame aura, the other would most likely be immunities. But he also has the fear aura flag, so some of these may be overlapping.

His saves are at 2x hit hit dice from the pen and paper book, so he saves as an 18th level fighter.

Looks like his breath weapon gets 3 shots. Avoiding that, resisting fire, and getting his AC down to 4 with stinking cloud really helps.

The javalens really only help on the second fight, which is the hardest one next to tyrax the way I ran it. After that I have 1-2 stinking clouds each time.

The bows, I wanted it for the two Half-elfs, since they generally killed him using bows, the other people were there just to slow him down. But this is the first run the too much money bug didn't hit me since I figured it out, so I ran with it just to make sure it kept working.

Looking at Tyranithraxus, he doesn't play like I remembered. For one thing, I thought it was immune to magic. In the Ruins of Adventure he has a flat 20% resist. Looking at his numbers, he doesn't seem to have this. His magic resistance shows as 0. He can be hit with magic missiles and these seem to always hit, so wands of magic missiles are kind of useful against him , and more importantly, he is not immune to stinking cloud.

Almost immune to it, but not quite. He doesn't seem to choke, but he does cough from it. This causes his AC to go from -4 to 4 in the status area; might be just a rendering issue, but I think it's legit. So that's a nice 40% chance to hit. He seems immune to slow, fire and lightning.

His flame aura I can't find for sure, but in the pen and paper game it's 2d10. Most of his stats are the same as pen\paper, at least for damage. It is resisted by resist fire. He can see invisible and strangely shows a status of displaced. A cloak of displacement causes the first hit in combat to miss, so that might mean your first physical attack on him will always miss. (Cloaks can also be abused, if you unequip and re-equip them in combat, it resets this and the next attack will miss)

I submitted a new run. It's very sloppy, as I just started, and played it when I just woke up, but it's a different route which I call the murder hobo route, as you'll see if you watch it. The route just uploaded to youtube:

The route is pretty much completely different than MSKain's route, I spent my time grinding in town killing patrols till I was strong enough to take the game. Since it's a new route I know there's a ton of changes to get more out of it, and sub-1 hour shouldn't be too hard; with some lucky runs could see it dropping even more.

It might be a good idea for me to twy a hybrid of this route and MSKain's, so I grab the dust of disappearance. If I change my levelups around some, (Grab fireball spell at the 23 min mark) and get sokol cleared sooner, that might be the better strat.

I did have some major issues with this run too, was short on expected gold, was a bit lower than expected in EXP, at least once hit the windows ket trying to get the splits to change, and ate a lightning bolt right off the bat in the final fight. I stopped time at the EXP screen from the town.

If we do get more runners and formalize the rules, ending time is one I think we should agree on. I'm also learning to having cycles at 6000 or even 10000, makes movement smoother.

Looking around, I see Jazz Jackrabit has these settings in the speedrun forums, think it might be "official" now:

core=auto cputype=auto cycles=40000

It makes movement outside of combat nice and smooth vs the 3000 I've been playing at, (Plus menus don't have that slow drawing speed) but combat on speed 0 is still a bit quick... unless you disable sound. The n movement outside of combat is a bit too fast, and combat.. I died because I couldn't turn quick off fast enough in one combat.

6000 + no-sound gives a nice movement and combat doesn't seem too crazy. It's a bit slower than a 386 33 MHz CPU though, so that seems a bit slow.

Hard trying to run dos games fairly when cpu performance varied so much from machine to machine :(

I know for the runs it's been ok to disable sound (Heck, it's an in-game hot key), but what about the cpu cycles? There's not really a default, but GoG uses 3000 which looks about the same as the speed in the videos I've seen. Haven't watched all of them yet, so haven't seen if you've mentioned the speed settings or not.
