The Geldh

The Geldh is a dark, forgotten and frozen dimension. You can get there using a reactor similar to the old reactor from the Pocket edition. Setting it on fire with an End Crystal, it teleports you to Geldh, forming a box of ice.

Biomes

Geldh has 4 biomes - an ocean of snow enclosed by gigantic walls, frosty bamboo thickets, icy wastelands and icy forests.

Escape

To get out of The Geldh back, visit 2 dungeons - Bone Tower and Guardian's Hall. In the Bone Tower, you can take a pickaxe with the highest level of efficiency. It will come in handy for the second dungeon. The Guardian's Hall has vex spawners that apply the Mining Fatigue effect. There are a lot of chests in the hall under a layer of ice. This ice can be broken with the Pick of Heat from the first dungeon, in one chest is the Heart of Heat, taking in your hand you teleport to the overworld.

Boss

But the Mining Fatigue effect will persist and you cannot get rid of it by drinking milk. In order to get rid of the effect, you need to defeat The Geldh Guardian, while getting rid of all the vex in the dungeon. The boss has 280 health, is accelerated and deals 23 damage.Only approaching it in the absence of vex within a radius of 40 blocks, u can remove the curse from yourself.
