I just finished Titan Quest on normal difficulty and would like to play the 4th act from Immortal Throne, on normal difficulty as well. Unfortunately, I played Act 1-3 in the regular game and didn't realize I should have played those acts via Immortal Throne from the get-go. When I import my character into Immortal Throne, it places me at the beginning of Act 1, I understand that's what the game does if I wanted to play on epic but I'm just interested in doing Act IV as a continuation of my normal difficulty playthrough.

Any ideas on how to fix this problem would be much appreciated, thank you!

Doesn't the expansion have its own separate executable? I seem to remember when I first played TQ, I also did a playthrough through the base game, then started up the expansion and imported my character. It's been a while though, so I could be wrong. I also have the game as retail disk version, in case that makes any difference.

Also, I know there's some cheat programs for TQ, so those might be a solution to your problem.

Worst case, just play through the game again with a different character, or just play through "epic" and then start the expansion chapter. Not ideal perhaps, but this kind of game was made to be completed several times. :P

Do you understand German? This is from the German readme file of Immortal Throne:

Been there, not so long ago. Good times. Luckily for you, I managed to get around it, more or less. Here's a link to my own thread on the Steam forums. Feel free to try the "alternate" methods described there that would supposedly allow you to skip directly to the part you want, and do let me know if they work. If nothing else, the portal method should save you much time and frustration.

Thanks and +1 for the replies everybody, it seems there aren't really any efficient options at all without modding so I finally decided to just install the Defiler mod, I didn't want to use it initially but I installed it just now to open the Rhodes portal.
Since I already beat Typhon, that doesn't count as cheating as Rhodes is the direct next point after Typhon is done. I'm certainly not going to play through act 1-3 on normal again, nor did I have any intention to do Typhon** all over again which would be an annoying waste of time so the Defiler tool was the most efficient option.

If anyone has the same problem, I downloaded it from here and it works just fine:

** Typhon was a most annoying boss fight, really poorly designed as it just takes a lot of time and no skill, just need decent gear. It's impossible to get enough resists for all his attack methods in untwinked single-pass play, that was very poorly balanced compared to the very well done rest of the game.

Well, I'd say it would probably have taken less to beat the boss again than it took you to ask around, find the mod, download it, install it and whatnot (and you'd have gotten a nifty blue item for your trouble). Still glad you got it sorted out. As per that boss, yeah, a major pain, but what's most irritating is to know that it wasn't supposed to work like that. Apparently, before the game was patched, you were able to destroy the big statues around you, and for each one you destroyed the boss lost one of the special attacks. But it seems that there were complaints of the battle being too easy, so the devs removed the ability to target the statues, thus turning the fight into a long boring grind. What we can learn about this is: devs shouldn't listen to the random internet d-bags.

Typhon was the first thing in the game that killed me on my last playthrough... with a damage over time effect shortly after I killed him (ran out of potions) :P

I also played a small chunk of the base game before I realised I should have been running Immortal Throne - might have gained an extra skill point from doing so (one of the quests awarded me a point the first time and when I did it again after importing).

It took about 2 minutes to find Defiler, install it and check the Rhodes box under the portals tab so that was surprisingly simple. Took me way more time than that to beat Typhon which was the very definition of un-fun and I really don't want to do that again. I'm still only level 32 and I have no "1337" gear, I just played the game normally doing everything once and completing most of the side quests. I was level 31 when I first tried Typhon and I could hardly make a dent into him so I then decided to grind an additional level. Must add that I was playing a dual wield conqueror with no points in defense mastery as I didn't carry a shield and all points in warfare which worked just fine all the way up to the Obsidian Halls. At that point, I had to go back to town and get something with fire resist against those double-teaming fire dragon creatures who'll burn you to a crisp in one shot if you get caught in the crossfire. When I faced Typhon, I only had good resists against fire, 40% wasn't that great but good enough. It's impossible to have decent resists for all of Typhon's attacks because you mainly need gear that enhances your attacks otherwise you can't make a dent into that guy. And completing those shard things isn't really an option in single-pass play. I managed to complete 3 of those shard things but only by grinding that extra level, if I hadn't gone back to grind I would have only had one item completed, the Jade Emperor one that boosts lightning resist (a measly 20% or some such). Typhon throws a different attack at you non-stop so you only have time to run in and hit him 2-3 times and then you have to run off immediately and even if you run off in time he could still hit you with an ice or poison or life leech attack and your health bar can drop to zero even after you've run away. It was aggravating, I even thought about just quitting the game because why finish a game if it stops being fun.
What you wrote about targeting the statues makes total sense, that would have been great if they had kept it that way! Would have been more strategic. The way the game is now it's an unreasonable spike, what's the point of making 99.9% of the game easy and then throwing in a boss that punishes you for playing the game normally, with normal gear.
As for the loot, Tyhon dropped absolutely nothing useful for me, that only added insult to injury. All this grind and not one item worth keeping, I got better stuff from random bone heaps lying on the floor, seriously :D

I died a whole bunch of times even before Typhon as I was making a glass cannon type of build that kills fast and dies fast, I never intended to play epic or legendary with this character so losing EXP for dying wasn't an issue as long as I just play on normal. It was also my first playthrough and I didn't know anything about what builds are good etc, I like to play a game organically meaning I don't want to look up build guides etc, just play spontaneously. That's why I was so miffed because it should be entirely possible to beat a game without having to have prior knowledge, without having to worry about what skills and builds work. Fortunately, skills can be changed in town for a gold fee but I couldn't change my second mastery. If I had known that defense is not a good second mastery for a dual wield warrior, I'd have picked something else. The new mastery from the expansion (dream) looks like it could work well with warfare but I'm not very motivated to play another character, it's a very good game but unlike Diablo 2 I don't get this immediate need to start another character or tackle the next difficulty, all I want is to play the expansion act, so far it seems quite fun but I'm getting killed way too fast due to my sucky resists. I have zero poison resist at the moment but if I change any equipment, my DPS goes down the dumps. Ice and pierce resist are almost nil as well and I see no way to boost all these without dropping my DPS so much that I'll end up dying anyway due to lack of killing speed. I don't mind having to deal with all the intricacies on a higher difficulty level (I love Diablo 2 on hell mode) but on a normal playthrough I'd just like to experience the scenery and not obsess over gear that much.

PS: When I finally killed Typhon, I ended up dying the same way you did and had to listen to the epilogue while tediously walking back up the stairs to go get my loot...very anticlimactic :)

I think that's your problem right there. You should always put points in both skill bars as those give you stats like +strength and +life even if you're not that interested in the skills. Moreover you should rather put points in the bars than in the individual skills anyway for the same reason.

Playing a conqueror with dual-wield doesn't make a huge amount of sense to be honest. The defense mastery is strictly about using a shield, so I'd recommend that you use one.

Better dual-wield masteries are Warfare+Dream, Warfare + Nature and others.

Yeah, I made it unnecessarily hard for myself by putting points into the main mastery only but now that I've beaten the game I looked up if others had problems too and it seems Typhon is generally seen as imba. I could have increased my survivability if I had just upped the defense mastery bar for basic stat improvement but I decided to put points into all those warfare skills like "hew", "dodge" etc just to see how they work out in action.
I think it's not very good game design if the game pushes you to build up HP, STR and DEX first rather than special skills and you only get into the really interesting use of skills on higher levels. Otherwise it's like playing Diablo 2 as a Tesladin (Holy Shock) where you use pretty much one skill throughout normal and nightmare and there's no need to diversify until hell, rather boring.

EDIT: I have in fact started another character with dream + warfare but I'm not motivated to play through the game again, it just doesn't have enough appeal to me. The scenery is really nice especially Egypt and it's fun to visit all the places I went to in RL but with monsters but scenery only impresses for one playthrough.
I'm now quite stuck with my crap build level 32 character at the beginning of the Hades expansion act, I have no poison resists and even on the first map monsters are killing me repeatedly due to my lack of supreme gear. In Diablo 2, you could finish all acts including LoD without any resists on normal.

That looks like something I might enjoy indeed, thanks for sharing.
Even though this isn't the answer to my question (which I figured out already), I'm going to mark this as the solution so you can get some of that extra rep, wouldn't want to let it go to waste by not marking any of the answers :)

No problem, I hope you like it. And don't hesitate to ask any questions you might have in the respective section of the titanquest.net forum. Violos (the author of the mod) and the rest of the regulars are very nice people.

Thanks :)
