Traps

Trap Types
Traps can be broken down into several different categories based on their primary purpose:
 * Damage: Able to kill enemies on their own
 * Environmental: Typically don't deal damage on their own, but use the map to affect enemies.
 * Assists: Used to help other traps and are typically useless on their own

Trap Mastery
Traps can be mastered by spending gems. Every level of mastery costs one additional gem to obtain. At 5, 10 and 15 levels of mastery each trap attains a new set of upgrades. Every level added to a trap will also boost some of its stats, and periodically decrease its cost.

Trap Upgrades
Each trap has Tier 1, Tier 2 and Tier 3 upgrades. The first two tiers give three upgrade options and can be applied to any number of traps. Tier 3, otherwise known as Ultimate, can only be applied to one trap unless using Engineering. There are only two Tier 3 options, with the third being taken by Empowerment. Empowerment allows a traps mastery level to be leveled up for a cost.

Trap Diversity
After the fifth trap of a type is placed, each subsequent trap will increase in price. Mixing up traps and creating combos is encouraged by the game to keep prices down, and create unique kill boxes. Despite this, it can be better to master only a few traps, and take the hit to cost.

Consumable Traps
Consumable traps can be used for free periodically. They are obtained throughout the game in vaults. It is encouraged to use them as much as possible, and equip a consumable fitting your trap loadout.
