Potion of Ridiculous Size and order of Bad Stuffs

[TheBestJohn]

We had a controversy recently in a game about a situation I would like to clarify: I kicked out a door and got 18 lvl monster with some Bad Stuff I don't like, then I played Wandering Monster card with monster lvl 20 monster with Bad Stuff - death, then I played 'Potion of Ridiculous Size' card on myself with the intention to die of that lvl 20 monster cause the card says that if you fail to win the combat the Bad Stuff happens automatically.

So the question is: can I choose the order of the Bad Stuffs of the monsters in play - die from lvl 20 monster and then no Bad Stuff from lvl 18 monster, OR should I suffer Bad Stuff in order of appearance of these monsters in combat - 1st Bad Stuff from monster lvl 18 and then from lvl 20?

Did not find the answer for this specific question, so your assistance is much appreciated.

The player in combat gets to choose the order.
