Wuthering Waves - Lampylumen Myriad boss 1st fight 

sometimes i just forgot to use it 😂, but some are powerfull imo, like the one dropped from bosses

@@gomuseo Any limit to them? Can you use them infinitely once you got them (with cooldown, I assume)? Or is there a limit of how many time you can use them? Another question, can the monster move be upgraded? Like, maybe after beating the same boss over and over again, we get more than 1 echoes and can upgrade the move?

yess, the echoes can be used infinitely tho it does have cooldown. and yeah it can be upgraded for more stats, but i think the moves still does the same. But i heard there"s shiny version of echoes (like in pokemon theres shiny version of it lol)
