They do this line attack that does insane fire damage because it does a bunch of damage ticks almost instantly and it's a one-shot kill to the player if you get hit. It's also not broadcast, nor is dodging very viable because it travels so fast.

It just needs to do a bit less damage and have a longer cooldown for the enemy between uses. It's okay that it's a dangerous attack, but getting one-shot when you don't even have the tools to deal with it yet feels pretty awful.
