Forgotten

Difficulty: Class 4
The Forgotten is the first, and most dangerous, level of The Forgotten Underground. It resembles The Abandoned Caves level as it is extremely hollowed out. This level, like the rest of The Forgotten Underground, should not be used for mining as The Normal and Deep underground are better as they contain for materials and are easier to get to. That combined with the extremely dangerous Shadow mob makes this level not worth it at all, pass though this level as fast as you can; it is not uncommon to be placed at the floor of this level upon entry meaning that leaving this level shouldn't be too hard. Unless you're unluckly.

Trivia
-Shadow mobs stick together in large groups near the bottom of the level-- don't stay at the bottom too long, you will be overwhelmed.

-You may spawn at the bottom when entering this level from the void, if this happens decide if you want to mine or leave; if you want to mine quickly tower or find some other way up to avoid the shadows at the bottom, but if you want to leave just dig down since you should be at around y=2.

-Mineshafts seem to be decently common here.
