Return to Castlevania Achievement Guide

Am I still on the island?
Reach the Castle's Outskirts for the first time.

In the cellars, find and talk to this dude, follow the path down and you should be allowed to enter the Castle's Outskirts

Into the vampire's den
Reach Dracula's Castle for the first time.

Only one exit in the previous area, just complete Castle's outskirt by climbing the castle gates. Don't fear the Reaper
Reach the Defiled Necropolis for the first time. Go through this exit in Draculas castle What is a man?
Reach the Master's Keep for the first time.
After clearing Necropolis, Dracula mentions he will find you once he needs you again. You will not run in to him on the rest of your run. Next time you die, he will find you in spawn

Here he will inform you to head to the clock tower. The game then says you can only do Castlevania dlc once per run.

Once you finish the clock tower boss, he will be waiting for you on the other side, go through the new door he provided.

This is the only exit within the castle if you go in through clock tower.

Good luck with the upcoming boss!

Death can be found in Defiled Necropolis

Death comes for us all... but not you!
You beat Death! Dodge death
defeat death without taking a single hit
I still have 8 lives
Have Maria's Cat deal the last hit to Death.
When in Castle's Outskirts, you will see a cat running around, catch that cat, it can be hard and frustrating, but it will reward you with a key.

Find the locked door in the same area to rescue her, she will tell you to pet the cat on the way out, if you do that, the cat will now be a pet for you for the rest of the run

pretty simple, when the boss is low on hp, just dodge him and let the cat kill him, hes kinda op (the cat) You don't belong in this world!
You beat Dracula!

You beat the last encounter of Castlevania without taking a single hit!

both phases of Dracula in Master's Keep, without getting hit.
a tip for the 2nd phase, a lot of his jumps and landing will damage you if you are on the same platform, when there is only one platform, time your jumps off of it and jump back on.

If you are having issues with the achievement unlocking from the boss, make sure to enable cut scenes

Currently trying to find blueprint drops for these items, please comment if you have found them

Knowledge is power
