So, I recently got Brimstone + Dr. Fetus on one of my runs. That's when I realized, they have no synergy! This would not do, so I quickly coded that up. After that run, I realized just how many tear effects were missing synergies with Dr. Fetus. So, I deci...

After the huge sucess that was, Dr. Fetus Synergies, I bring you the next mod in the series: Spirit Sword Synergies! This was suggested by quite a few people, so it seemed like a logical next step. The Synergies! Brimstone/Azazel/Azazel B: Gives you a lase...

You asked and I have answered. So, here it is! Epic Fetus Synergies! This is by far the most epic synergy mod so far (pun intended). Without further ado, let's get into it. The Synergies! Azazel: The regular brimstone synergy, but with shorter range beams....

I've finally decided to do the classic, "no synergies" item, Mom's Knife! This was very fun to make, as there are a lot of cool items with no Mom's knife synergy! The Synergies! Pop!: Spawns several pop tears when the knife reaches it's peak. My Reflection...

I think most people would agree that Judas' Birthright is one of if not the most creative birthrights in the game. However, their are a quite a few items that I feel could have synergies, but don't. So, I added them! The Synergies! Anarchist Cookbook: Trol...

I've been debating releasing this mod for a long time based on a simple fact: it's much smaller than I would like (that's what she said). There are two main reasons for this. First off, a lot of items already have a synergy with Flat Stone, so there weren'...

Hey. It's been a bit longer than I would like, but I've been really busy lately. Anyways, here it finally is: Monstro's Lung Synergies! Before we get into it, I just wanted to say thanks to Ham Man for some ideas as well as testing, he was a great help whe...

Funnyman Modding Enterprises is BACK! With another BANGER! (no pun intended) (they also do commissions so hit them up lol) This mod adds 12 new synergies between Giga Bombs and bomb related items. The list is as follows (and yes, they do stack.): Bob's Cur...

Akeldama synergies with your tears! This mod turn Akeldama tears to Isaac's tears This include every tears the player can have, like Cupid Arrow tears, Spoon Bender tears etc. Some tear effects are now blacklisted because that was too dangerous or weird. H...

Car Battery has no effect with 45% of the activated items, it's time to change that! This mod makes Car Battery work with additional 26 active items! Almost all of the synergies do not simply activate the same effect twice, they actually add a unique secon...

Pretty lame that such an interesting item doesn't work with tear modifiers. Since it also is a planetarium item, that had to be fixed. In case Repentogon is installed, mod uses it's features for new/improved synergies. Some little customizations, alike not...

If there’s one thing we’ve all wanted, its for Tractor Beam to interact with the worm trinkets, right? Right? This mod re-implements the Tractor Beam item and adds a bunch of new interactions and synergies, including but not limited to: Worm Trinkets(!!!) ...
