When you’re playing Megabonk, getting more weapon and tome slots can really change how you play, especially as you get into those tougher runs. You start with a pretty small number of slots, which makes every single upgrade choice super important.
Once you unlock more, you can use a wider variety of weapons and tomes, and that’s when you start to get seriously powerful. It might seem weird to spread your upgrades across more weapons, since that can lower the damage of each individual one. The real secret is in how tomes and a lot of the item effects work. If this game remains fun, it may become one of the best games on PC of all time.
How to Unlock Additional Weapon Slots in Megabonk

To get that first extra slot in Megabonk, all you need to do is complete 25 quests. That’s a pretty big milestone right there. It lets you start building more diverse loadouts, which means you can increase your damage output or your defensive abilities—but don’t rely on how luck works.
After that, the second extra weapon slot becomes available once you’ve completed a total of 35 quests. The developers actually made it so this progression isn’t a huge grind, which is great. It means you can get your hands on these crucial upgrades a lot sooner and really feel the difference in your runs. While this may not be a free game, it is better than many of the best free games on Steam.
The real benefit of having more weapon slots in Megabonk isn’t just about carrying more weapons. It fundamentally changes how your upgrades and tomes work with your entire kit. Now, you might think that adding more weapons is going to dilute their power since level-ups get split, but the way global tome and item effects work, it actually creates a huge compounding advantage.
How to Expand Tome Capacity in Megabonk

As you play Megabonk, you’ll find different quests with conditions that can change based on the map you’re on, the character you’re using, and other things that happen in the game. By finishing these quests, you’ll slowly get closer to expanding your Tome capacity. It’s not a quick thing; it’s a reward for sticking with the game and playing it a lot.
The developers have listened to the community, and the grind to unlock new slots has been significantly reduced. Back in the day, it took a lot of quests to get a new slot, but now, you only need to complete 35 quests to unlock new Tome slots. This change makes it much easier for you to grow your character’s power and makes the game feel a lot less punishing. Once you hit that 35-quest milestone, the new Tome slots will be available to buy in the shop, ready for you to use in your next run.
Having more Tome slots gives you a huge advantage. Tomes work globally, which means their effects are multiplied across all your equipped weapons. This lets you stack powerful global bonuses, turning a solid build into an absolute powerhouse. For example, if you have two different weapons (one for clearing out mobs and another for taking down bosses) you can make them both incredibly effective by having a full set of Tomes.
These global buffs amplify your entire arsenal, making those late-game runs much smoother and easier to manage. So, if you’re serious about getting deeper into Megabonk, I’d highly recommend you focus on completing quests to expand your Tome capacity.
Tips for Maximizing Your New Slots

On shorter maps, you might not feel the benefit of maximizing slots in Megabonk right away. The runs end before your weapons have a chance to fully scale, and dedicating early level-ups to multiple weapons can feel less impactful than just focusing on one or two. But the real strength of a fully loaded arsenal comes out on those longer, higher-tier maps.
You get so much more time for all your different weapons to grow, with each one benefiting from all the overarching buffs you’ve collected from your tomes and other items. The secret to making your new slots work is knowing that a lot of the most important stats, like attack speed, projectile count, and critical chance, apply to your entire kit. This means when you get a single upgrade for a tome that boosts crit chance, for example, it’s going to improve the critical hit potential of every single weapon you’re holding, not just one.
So, having four weapons all getting those global multipliers is almost always going to lead to a much faster and bigger power increase than just sticking to two. You should think about a balanced approach. You can use one or two weapons for area-of-effect damage to clear out hordes of smaller enemies, and then use another slot for a powerful single-target weapon that’s perfect for bosses.
This gives you a lot more flexibility and lets you adapt to different combat situations. On top of that, stacking multiple tomes in your expanded slots amplifies their effects like crazy.
Every global bonus from a tome gets more and more impactful as it applies to a larger number of active weapons. While it might be tempting to concentrate on a single weapon for maximum baseline damage early on, leaning into the multi-weapon strategy on longer runs will ultimately give you way better scaling and make the late-game a whole lot more manageable in Megabonk.
