Highlight to read.The mercenary guild: Have you noticed the grating in the main room? You have to click on the wall beside it to open it. There is a secret passage down to a room with several ... of the sword. I usually take that secret passage down until the bad guys notices me, then run back again and close the grating, by clicking again, standing well to the side while it closes and then hack away at the caught prey through the grating
. Repeat if nessessary. There is usually somebody stuck between the chest and a crate who can be gotten at while you stay in that room, he's to stupid to get out of that position. The grating can be used from the other side too. Make sure it is open, find some masters of the sword and make them follow you there (this can be a bit tricky), click on the wall, duck under the grating while it is closing, stay away from the opening until it has closed, and then start slashing at the enemy. It's not 100% safe but it is good enough.
End part 1.
The titans stronghold: It's not exactly a safe place, you need to stay far away from the titans. There is a distance where you can see the titans but they cannot see you (which is logical since they are much larger than you). To find that distance cast invisible and approach the titan(s) until the frames around your party turn yellow, then back up again until the frames are green. OR Press - near the map to show more of the dungeon, when the red dots are about 1-2 milimeters from the end of the map you are at the right place. Now you have to get your aim righ, which is tricky, most arrows still misses. I think it is easier to hit if the gang looks up slightly (one hit on "page down"). When the aim is ok switch to spells, my favourite is fireball, air or mind spells do not work, or drink haste potions and use blasters. Also most titans can be killed this way, but it means turning the corners in the right order, the rule is: if the frames turn yellow when you approach a corner, go back and try another way.End part 2.
Tunnels to eofol: Peter2 has already told you about the narrow tunnels, so I'll just add .The first "safe" place is the glove shaped place to the left just after you get into the tunnels, the behemots inside it usually dont move out of the room they start in, and unless you move around too much inside, the ones in the main tunnel do not realise that they can get in there. Again, it's not 100% safe. Slow is a very useful spell against behemots.End part 3.
I hope this helps.
