If an apparition flies by, and your towers are busy killing monsters, click on the apparition to have the towers target it. If a monster with a high armor level approached however, a strong gem might be very useful - the monster's armor will absorb most of the damage weaker gems can inflict.Ĭlick on a monster to view info about it, but also to highlight it for your towers to shoot. It's better to have more towers with somewhat weaker gems in them, than a few towers with stronger gems. Look at the range indicator (yellow circle) of the inserted gem to see how far it can shoot, and place it in a tower that can give it the longest path to cover. It might be worth placing a tower at one square distance from the path instead of right next to it. If you want to shoot them, they should be in the gem's range you want to place in the tower. Place your towers in positions where they can cover the longest path possible, but also look out for beacons, shards, nests, and tombs. Try to avoid making gems containing more than three base types. 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. So if you want to use the special ability of a gem, combine it only with gems of the same type.


If you combine two gems of different types, you get both specials but with a decreased power. Pure gems have the strongest special abilities. These bonuses can be further increased with the Dual gem and Triple gem mastery skills.

Dual gems are superior to pure gems, they get bonuses to their damage, range, and firing speed.
