What's the downside of dying?

I've died a few times already. If another player character is near me, they can help me up. Otherwise, I can wait 60 seconds (which I haven't done; I'm impatient), or I can respawn instantly.

What is the downside of any of this? What do I lose by dying?

Solution 1:

According to a couple posts in this thread, you lose any experience gained in the fight where you died. That is, you don't earn experience unless you beat the opponent.

I just completed the tower, but it's doesn't seem there is apart from if you have learned moves during the fight and you die, you lose the moves experience.

yeah there are no penaltys. the exp you gain towards learning moves in that fight is lost. you only get that exp once you beat them, but if i beat 1 person and die a second later i don't lose anything.
