Until the official guides are released, lets make a thread documenting the effects of all the Status Effects in the game. This post is incomplete, but I will add to it based on information provided by other users.
- Heroic: Increases power and attack greatly. Granted for 2 turns when matching one Gem of each color in a single turn (cascades or otherwise).
- Terror: Characters inflicted with Terror only receive half the benefits from positive status effects like Barrier and Haste.
