When you get a Monster appears from a Location card if you do not fight it is it is put back in the cup. lf so, when is it removed & put back in the cup.

If you evade it or if it knocks you out, it is put back in the cup. If you win combat, it is taken as trophy. It is never put on the board.

The exception to this is if the location encounter states that a gate opens AND a monster appears. Then the monster stays on the board as normal per the opening gate rules.

Thanks to you both.
