Arms of God Best Builds, Boss Guides & Hidden Secrets for 2026

After about 30 hours of getting my face melted by demon hordes, I've found a few weapon merge combos that feel borderline unfair. The beauty of this game is that there's no single best build , different character abilities completely change what weapons synergize. But some merge recipes are strong no matter who you're playing.

I should mention upfront: the game launched in Early Access on June 8, 2026. Dark Jay, the solo developer, could rebalance everything next patch. What's working today might not work next week. That said, here's what's been crushing runs for me.

The Burn-Tick Machine

Start with any rapid-fire weapon as your base. Merge a fire-element weapon into it. Then merge a weapon with the projectile count stat into that. What you get is a stream of fire projectiles that stack burn so fast bosses melt before their second phase.

Throw in a blessing that increases status effect duration and the burn ticks start out-pacing most healing mechanics. I used this setup on one of the AoE-focused characters and literally walked through Act 3. Not exaggerating. The screen was just numbers. My Steam Deck fan kicked into high gear from all the particle effects.

One catch: you need the initial fire weapon by level 10 or so. If RNG doesn't give you fire drops early, pivot to lightning or physical. Don't force a build that isn't getting support from the drop tables.

The Knockback Fortress

Take an AoE pulse weapon , the kind that damages everything in a radius periodically. Merge a knockback weapon into it. Now every pulse pushes enemies away. Merge another weapon with attack speed into it and the pulses fire faster.

You end up standing in the middle of the map doing nothing while enemies bounce off an invisible wall. This build falls off against bosses that resist knockback, but for wave clear it's genuinely hilarious. I think I watched YouTube on my second monitor during one run with this setup.

The downside is boss kill time. Without a dedicated single-target weapon, Act 4 bosses become marathons. I usually keep one crit-focused weapon in my loadout even with a knockback fortress build, just to have boss damage.

The Crit Stacker

High base crit weapon plus merge weapons with crit multiplier stats plus blessing that adds crit chance per consecutive hit. Every 5th or 6th projectile is a critical for 4x damage. With 5 weapons all firing simultaneously, you're critting constantly.

This build is tricky to set up because you need specific weapon drops and specific blessings. But once it comes online, around level 30-35, it outscales everything else in the game. I killed the final Act 4 boss in under 40 seconds with a crit-stacked Sacred Crux in beam mode.

The problem is the ramp-up. Levels 15-25 with an incomplete crit build feel terrible. You're squishy and your damage is below average. If you can survive the mid-game, the late game is a victory lap. If not, you die at the Act 2 boss with 25 minutes invested and nothing to show for it.

Boss Strategies That Actually Work

Bosses with projectile attacks are countered by movespeed blessings. Just run in circles. Simple but effective. Bosses that summon adds reward AoE weapon setups because killing the adds often debuffs the boss. Bosses with charge attacks get stunned if you hit them with a knockback weapon during the wind-up. I don't know if that's intentional or a bug but it works consistently.

The Act 3 penultimate boss has a phase transition at half HP where it floods the arena with ground hazards. If you don't have a movement speed blessing by then, you're basically dead. I learned that one the painful way. Twice. Now I never enter Act 3 without at least 15% movespeed from either blessings or Cathedral upgrades.

Several boss arenas have destructible elements: pillars, statues, braziers. Breaking them drops healing orbs. The Act 2 final boss arena has four pillars, each drops a heal. That's four extra lives if you space them out during the fight instead of breaking everything at once.

Cathedral Secrets Most Players Miss

The Alchemy Chamber has hidden blessing upgrades that don't show up until you've unlocked at least 10 other blessings first. These are the ones that modify how blessings interact with each other , stuff like blessings that add projectiles also adding 5% crit chance. Account-wide effects that make every future run stronger.

The Bell Tower doesn't just unlock characters. Each character you unlock adds their starting weapon to the global drop pool for all other characters. So unlocking everyone isn't just about variety , it actually makes every run stronger by giving you more weapon options. Counterintuitive but true.

One more thing about the Sacred Crux: its beam mode at max level has piercing that goes through terrain. Its aura mode at high level applies a random status effect from any weapon you're holding. If you've got burn, poison, and slow weapons equipped, your aura pulses apply all three simultaneously. It's like having a sixth weapon that's also a debuff engine.I should mention one more thing that doesn't fit neatly into any of the sections above. The Early Access build as of June 2026 is remarkably polished for a solo developer project. Dominik Sójka clearly put the time in before launching. I've encountered maybe two minor bugs across 50-plus hours. The frame rate on Steam Deck is locked at 60 even during the most chaotic Act 4 wave sections with every weapon firing and particle effects filling the screen.

The weapon balance isn't perfect , some weapons are clearly better merge bases than others , but that's part of the fun in a roguelite. Figuring out what's strong and what's a trap is half the game. The other half is execution. And the metal soundtrack.

If you're on the fence about buying this in Early Access, I'd say go for it if you like bullet heavens. The content is substantial for the price. Four full Acts, 10 bosses, 10 characters, 60-plus weapons, 100-plus blessings, a meta-progression system that makes every run feel meaningful even when you lose. And the full release with console ports is coming Q4 2026 or Q1 2027. Your Early Access purchase supports a solo developer who clearly cares about their game. That's worth something in my book.
