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

In Hades, if you look at the 'normal' boons list, there seems to be 22 slots (4 rows that alternate 5 or 6 slots).

Is that 22 limit a hard limit, and if you reach for your 23rd boon, what happens?

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.
