Inventory Management — Synergy Guide

Discover how items combine in Enter the Gungeon! Learn about Synergy Factor, how it works, and explore a list of powerful synergies like Akey Breaky and AI Assistant.

Hey there! So you're diving into Enter the Gungeon and want to understand how those sweet item combos, called Synergies, work? It's like finding out your favorite snacks taste even better together! Basically, some items, when you have them at the same time, unlock a special bonus effect. You'll even see a little light blue arrow pop up to let you know you've activated something cool. These Synergies got a big overhaul in the Advanced Gungeons & Draguns Update. Now, every synergy has a name, and you can even check what's synergizing in your Ammonomicon. Just pick an item and it'll show you the other pieces of the puzzle. ### Synergy Factor Now, about how these synergies show up. There's this hidden stat called 'Synergy Factor.' Think of it as the game's way of nudging you towards a synergy if you haven't found one yet. It's a multiplier that increases the chance of finding an item that'll trigger a synergy with what you're already carrying. Synergy Factor starts pretty high (around 1.8x more likely on a fresh save, but can be as high as 6.0x on a brand new save file!) and goes down each time you get a synergy in a run. It resets when you win or start a new run. After you've gotten a couple of synergies, it doesn't really affect things much anymore. Here's a rough idea of how it changes: * 0 Synergies: 1.7999882x more likely * 1 Synergy: 1.120989x more likely * 2 Synergies: 1.02681x more likely * 3 Synergies: 1.00829x more likely Heads up: If you've reached The Forge at least 3 times, your starting Synergy Factor might be lower than on a completely fresh save. Also, dropping a synergy item *before* opening chests won't reset your Synergy Factor. ### List of Synergies This is where the fun really begins! Here are a few examples of what you can find: * 360 Yes Scope: If you have the Scope, spinning 360 degrees gives you a 3-second buff. Your next shot during this buff deals 1.5x damage, and this can stack up to six times! * Absent Minded: Combining The Membrane with Bouncy Bullets makes The Membrane's shots bounce 4 times and become homing. Pretty neat! * Added Effect - Fire: If you have Alpha Bullet and Hot Lead, your first shot from each magazine will be a fire bullet. * Added Effect - Ice: With Alpha Bullet and Frost Bullets, the first shot of each magazine becomes an ice bullet. * Added Effect - Poison: Pair Alpha Bullet with Irradiated Lead, and the first shot of each magazine will be a poison bullet. * Akey Breaky: Got the AKEY-47 and the Shelleton Key? Your AKEY-47 gets a damage boost (10 damage per bullet), infinite ammo, and it even looks like a Shelleton! Just a heads-up, it won't open locks by shooting them anymore. * AI Assistant: If you have Roll Bomb and the iBomb Companion App, your roll bombs will bounce and you can manually detonate them with the iBomb Companion App. Handy! Keep an eye out for these combinations – they can seriously change up your runs!
