What causes bosses to appear in Loop Hero?
Bosses seem to appear somewhat randomly, not after a certain amount of loops. Is it random, or is there something (number of kills, number of buildings etc.) that causes bosses to appear?
Solution 1:
As you place tiles in the world, there is a bar that fills up slowly from left to right, below the day's progress bar. When this bar is completely filled, the boss for that act will appear. You can use this to time your boss interactions if you're not ready on a certain loop.
Placing any tile into the world directly adds a small amount to this bar
