Is there a limit to common boons, and what happens if you reach it?

OK, so lets do some math.

If we believe the wiki: The elysium boss is room #36. So that means there are 36 rooms where you could get something the 6 styx doors.

So we get to 42.

• Bosses and the room before the boss cannot be a boon, (-6, so 36 left).
• The first room of each floor (and the 2 firsts of styx) do not have rewards, ( -5 we get to 31.)
• Out of the 6 doors of styx, there is max 3 boons. (-3, so 28)

So we would only need for the game to give no hammers or boons 6 times out of 28 possibilities (21%) and this can be curved if the player has a heavy boon start.

So knowing all that, I'm gonna go on a guess that the game stops you from getting more than 22 boons.
