I've been grinding level 10 for a few hours now and this is what i came up with.

The particularity of this game's boss fights is that you can only have a chance to attack the monster twice in a row, which mean that the ideal run will have only 4 rounds, not considering the start, when he just stares at the player and stops at 7 or 8 seconds (igt), sometimes even 10.

The monster can do 3 things in his round: -Attack with a single tentacle, might be the fastest out of all of them -Throw random stuff in the air -Give the change to attack placing an ice block

He can also do nothing, but unfortunately this doesn't end his round, so it's literally a time lost and you'll need another action to end his round.

So, the fours rounds are going to look like this in an ideal run: -The monster gives the change to attack -He either attacks or gives the change to attack -The monster does the opposite of what he did on the second round (If the monster attacked on round 2, then he can't on round 3 because it would be three times in a row). -Finally he gives the change to attack, but on 10 and 20 he does it on the third area so you can reach the elevator faster.

There is a 0.4% change of happening, but if you consider level 30, where it doesn't matter wherever the last attack is, then it raises up to 1.17%. Hopefully, someone will have a perfect rng run and manage to get a run under 50 seconds.
