Crystals

Steam Inventory items that raise the damage of one tower type in every run. Each crystal's shape follows its tower; its colour, its rarity.

How to get one, and the odds

A crystal binds to ONE tower type and raises the damage of every tower of that type for the whole run — Common +5-10%, Uncommon +10-15%, Rare +15-20%, Epic +20-25%, Legendary +25-35%. On the Collector, which deals no damage, it raises the Collector's speed instead.

Only one crystal counts per tower type; if you own several for the same tower, the biggest bonus wins. It is dropped once per Steam account, by clearing wave 50 on difficulty 3, and it is now in your Steam Inventory — you can trade it with other players on the Steam Market.
