After decades of preparation, training, and perfecting your skills… this is the test you’ve been waiting for: The Gem Craft Labyrinth! Dual gems are superior to pure gems, they get bonuses to their damage, range, and firing speed. Triple gems get even higher bonuses. These bonuses can be further increased with the Dual gem and Triple gem mastery skills. Pure gems have the strongest special abilities. If you combine two gems of different types, you get both specials but with a decreased power. So if you want to use the special ability of a gem, combine it only with gems of the same type. But enough gem info for now, get to playing this tower defense game!!
If you want a gem to have a strong special ability, but also benefit from the triple (or dual) bonuses, create 2 or 3 grade 1 gems, each of a different type, combine them together, and then build onward using only pure gems of the type you want to boost.
Try to avoid making gems containing more than three base types.
Place your towers in positions where they can cover the longest path possible, but also look out for beacons, shards, nests, and tombs. If you want to shoot them, they should be in the gem’s range you want to place in the tower.
