the destroyer is shooting rainbow lasers which are making the fight a whole lot harder (not gonna complain but it's definitely harder than vanilla). this screenshot doesn't capture it crazy well, but it's shooting giant bursts of these lasers which give status effects too??? did calamity add this or is it some other mod?????
