Hunting Tools

CF operations feature four Hunting Tools: unique deployable devices based off various tools in Monster Hunter (see their respective Trivia section for more information) that can be used to immensely help the player in various ways. They are unlocked by clearing certain CF operations, but the player can only use two different Hunting Tools in each CF operation at a time, chosen before starting the operation.

Hunting Tools' count varies with the operation; refer to the respective CF operation's additional information for details.
