Part 101: Bonus Update 54.5: Darkstone TowerBonus Update 54.5: Darkstone Tower
Getting through Darkstone Tower is pretty straightforward once you work out what you're supposed to do. Ideally, you'd want everyone to have 2500 HP or so for the third floor, which is achievable if you've been levelling everyone up evenly and stacking Endurance bonuses on your more fragile characters. Failing that, just set a Lloyd's Beacon at a well that boosts HP or magic resistance.
All of the gongs you need to hit, and the skulls you need to talk to, are in the indentations in the central walled areas: the left side of the 3, the top of the 4 and so on. The statues are around the outer edges of each floor.
See you in the Southern Sphinx!
