Baldur's Gate: Dark Alliance [Extreme Difficulty] #10
Ah, the Onyx Tower, Dark Alliance's version of a final dungeon zerg rush. Your on your own from here on out. There's no more shopkeepers for you to stock up at. Luckily, every single crate in the tower is packed with enough supplies to drown a person in. Seriously, there is no chance that your ever going to run out of health or mana potions or arrows. Seeing as you can't sell anything from this point on, there's no reason is picking up items that you don't have a use for. Much of what drops is very good, however, so if any of your equipment is lacking, it might be an idea to check to see if it's better than what you've got.
As for the monsters, the stone imps are easily the most frustrating monster in the entire dungeon. They deal far more damage than anyone would reasonably expect and come at you in groups. Ironically, some of the larger machinations aren't actually that threatening. Only the one with the spinning blades is really all that dangerous. Do as much damage from range as you can before they get close to you. Everything in the tower has a large health pool, so keep that in mind.
We're coming up on the end! The grand climax to such a riveting story!
