Is Mad Alchemist supposed to be beatable at all?

[Lord Radai]

Just what the ♥♥♥♥? Spams slimes which poison you, summons lightnings that follow you and shoots red orbs that reduce your HP. How the ♥♥♥♥ do I beat this ♥♥♥♥♥♥♥ boss?

[William Wave]

Lure the alchemist at platforms and deal damage, wishingly with a weapon that has medium or high stagger like a sword or a scythe. When you run out of stamina, move to the other platform and repeat. Kill slimes when they are spawned, keep amount of them in a limit of two. Dodge lightnings, fireballs and dark knives by running and jumping. Also farming levels before the fight will help.

The Alchemist is actually easy but there's a trick to it. What weapon are you using?

Regardless if it's really annoying you, the Alchemist is optional. Skip it, come back later.

He has very low HP. Whack at him when he's on the platforms (left or right) and don't waste any time with his summons. He' s a bit of a roulette boss so it might take a couple of tries to get him but you should have no problem.

[Lord Radai]

Thanks for the help. I got lucky he didn't summon many slimes so I just spammed attacks until it died.

Tip: use either a poison vial (yes, the poison using alchemist is vulnerable to poison), or the fire weapon buff item when you face him.

This was the easiest boss ever. I just happened to find out if you stand right up next to him and slash him, he can't do anything and you can just slash him until he dies. I had one slime thing get me and that was it.

The Alchemist is weak to elemental attacks....like all the elements.
If you got any weapon buffing consumables, they will greatly increase the amount of damage you take off his health bar.

Also, at half health he speeds up the rate of his attacks and the fight can quickly turn into a dps race.

Most of his attacks count as magic, which is just plain broken in this game. Getting hit by magic stuns and pushes you without giving you i-frames. Meaning a good hefty spam of projectiles can stun lock you to death.

You best strat is to end the fight as quick as you can, to avoid his Phase 2 spell spam. As I already stated, he's weak to all elements, so a bless/stained page or a jug of pitch fire applied to your weapon will got a long way.

Finally, if you're not hurting for gold, you could try hitting up a merchant for a big stack of light vessels or fire pots and just pelting him with those non-stop. Not effeceint, but funny and effective.
