When you attack the Boss, it nearly always will be able to Counter- Attack. Note that on the Boss Mat are different Enemy Die modifiers for each type of attack. Sometimes a modifier may show ‘lose Focus’ or ‘lose Health’; this effect happens after the hero resolves their attack. For example, your hero loses 2 after they Cast a Spell. There is also a special instance for the Torch die result when used by the Boss:

Boss’s Torch: In addition to moving the torch down one on the track, it triggers the effect listed on the Boss Mat. If moving the torch also causes an Enemy Action () then resolve the Torch die’s effect first.

For this Boss, when a Torch is rolled, all heroes within 1 room are dealt 2 damage.
