While descending a dunjon, and on the 4th floor in search of the next set of stairs downwards to the 5th, I seem to have stepped into a trap. The walls caved in all around me, apparently.
Luckily I had 6+ spell units, so I was able to cast a Word of Recall and zap myself back up to the surface by the entrance of the dunjon. I suppose I could have alternatively cast level 5 spell “Gate” and teleport somewhere else in the dunjon, although I generally don’t use Gate as it teleports to a random location, and I prefer knowing where I am. Don’t know what I would have done had I not had at least 5 or 6 Spell Units. Reminds me of a wizard teleporting himself into a solid stone wall.
Word of Recall is a lifesaver sometimes. I even found the King’s Castle.
Another weird thing I found is a dungeon that seems to lead nowhere. You can descend the dungeon, and while in the dungeon, you can step one square south, but other than that, it doesn’t lead anywhere, unless there is something that I’m missing. It’s pictures below. Though I’m pretty sure Realms of Quest II overland map and dunjons are all procedurally generated. I hope there are more than 10 dunjons in the overworld map, as it’d be a shame if the dungeon to nowhere prevented obtaining the final 10th orb.
