Straight out of his role in fellow hard-as-nails game The End of Nigh comes the enigmatic and creepy Ash! This mod makes Ash a selectable character. Select him and you'll start with black hearts, bombs, a How to Jump manual, and a Cartridge! Hopefully Ash will have better luck here than in his own unforgiving world.

Bombby might not be the most menacing... save for the fact that he's a sentient bomb. That said, he has fears just like one! He doesn't want to blow up for just anything! He'll run away from enemies and fires and then explode from time to time! However, sometimes, Bombby will find his resolve and chase your enemies down. Whatever happens, Bombby will be by your side. Just take good care of Bombby, okay?

Lil Vis (New Familiar)

Lil Vis may not look like much - It is a disembodied torso after all - but it sure does pack a punch! This mod adds the Lil Vis familiar. Once gained, this little pal will float around, opening up and shooting blood beams at any enemies unfortunate enough to walk into its line of sight. Bring them into range and let Lil Vis rip!

Satanic Ritual

Nothing like a little sacrifice to get to where you're going right? This mod adds the Satanic Ritual that allows you to sacrifice your familiars to the devil to receive devil items. What you get depends on what and how much you sacrifice. Give up a holy familiar and the devil will be overjoyed, rewarding you even further. Sure you'll be no better than Mom, but it's survival down here... right?

Familiar Doll

  • 15.6 KB

Now here's something to bring out the familiar in all of your enemies. This mod adds the Familiar Doll trinket. With it, bosses have a chance of randomly dropping items thematic to their being. Monstro will drop his tooth or little Monstros. Pestilence will drop Leprosy and other sickness related items. Each boss has a certain drop that might take the place of their usual drops. Will you get lucky?

Isn't it better to make peace instead of war? We think so. This modder does too. That's why they added the Condolences item! With this handy little rose, you can form contracts with enemies and bosses to make friends. They will fight at your side and can only die to other enemies. Keep in mind you can only have one of each enemy type and can't kill your friends. Utilize your pals and remember their strengths and weaknesses!

When the world seems frightening and looming, you know your old security blanket will always have your back and keep you safe. This mod adds the Security Blanket as an item, healing one red heart and granting one soul heart when obtained. If that wasn't enough, when entering a boss room, your Security Blanket will grant the Holy Mantle's effect to soak up one free hit. Quite a bit more than a comfort zone to hold on to during bed time.

Expanding 06 - Uriel

Get ready to embrace purity as you make your death march through the cellars. This mod introduces a new playable character in the form of Uriel. Uriel is a small angel boy with divine powers. He has a little pure familiar that helps him fight and can call down heavenly beams. More than that, if you can remain frugal and not spend on wanton items, Uriel actually grows stronger for your vow of poverty. Use it to your advantage and challenge the depths for the purity of little Uriel's soul.
