I'll go grab the rulebook to quote it, but the short of it is:
Once the boss comes out, The Consul player may no longer spawn monsters from spawn points.
Instead, for each spawn point remaining, the boss (ie, Starfire in the base game) may be activated that many times.
Let's say you have 4 spawn points when the boss comes out. The boss gets activated 4 times before the next round starts.
No, it's only 1 extra activation...
