Heres how it works: there is a team of 3. There is stuff to find, like 5 iron ores, 3 coal ores, ETC (ores only). They are hidden in a cave with torches. The faster your team find all the things hidden in the cave, the more gems, shards, and XP you earn. To show that you found them, you have to mine the ores. There will be some obstacles for ores. Some ores are found after doing a parkour. Others will be found by climbing a ladder, but with skeletons.
