Traps
Traps are hovering hazards which explode when one or more targets come close enough. A trap will either deal fire-based damage to all targets within its area of effect, or inflict a status condition.
Traps are a feature of each zone, however they generally do not appear in Forest except in certain quests. They can be in rooms or hallways. Traps are often found in groups, and often guard loot boxes or switches. Traps are normally invisible until triggered, however a player can use a Trap Vision to reveal any traps within its radius. Lieutenant Mantle grants always-on trap vision while equipped. Android characters have permanent trap vision.
When a trap is triggered, it briefly becomes visible to all players, then explodes after a few seconds. A trap will either deal damage or will inflict one of poison, paralysis, confusion, frozen, or slow. Visible traps can be attacked with ranged weapons or techniques before they detonate. They are immediately destroyed when hit by any attack. Some traps may follow the target player around by hovering directly over their head before exploding; these traps must be targeted by a technique such as Zonde or attacked by a fellow player.
Traps used by players
All android classes can deploy traps of their own, namely damage traps, freeze traps, and confuse traps. Androids start at level 1 with 2 of each trap, and gain more of them as they level up, with each class gaining different amounts of each trap throughout level progression. All player-owned traps max out at 20 of each type of trap. They are replenished by leveling up, using a healing ring, the Medical Center, or when dying (whether you revive or respawn).
Player-deployed traps will affect monsters and not other players. After deploying they take a moment to "come online" and once they do so, they immediately detonate when one or more monsters are nearby. The time spent to "come online" is reduced in higher difficulties. A player who deploys a trap can immediately detonate it by shooting it with a ranged weapon, such as a handgun or a needle.
Players cannot deploy traps in boss arenas.
