A Guide to an Atomic Bomb Build in AI Limit

Game Guide by Ornstein on May 06, 2025

You're about to master the most OP build: a high‑risk, high‑reward spellcasting setup that shines in New Game Plus. Begin with a save that doesn't have Mercy equipped—although Mercy would be ideal since it scales with both Technique and Spirit.

This guide focuses on a High‑Spirit spellcasting build that demands precision and timing.

Equipment and Scaling

You're recommended to wield the Red Deer, but your ultimate goal is to equip Mercy because of its superior scaling with Spirit.

You should invest heavily in Spirit and Technique to maximize your damage output. Reaching a Spirit level of 86 alongside substantial Technique and Life proved most effective in testing.

Core Spell: Minimum Pain

The terrible spell "Minimum Pain" is at the heart of this build. One hit can kill you, but this won't do that right away. One chip of damage is all it takes to kill you.

The power of this spell goes up straight with your Spirit level, so it's important to get your Spirit as high as you can.

Sync Cost and Activation Sequence

You must first reach a 120% sync rate before you can cast Minimum Pain without using up all of your sync. When you reach that level, calling Minimum Pain, which normally costs 100% sync, will not use any sync.

Immediately after casting, you should activate the Sacred Blast Pral (carry only one) to extend your offensive window. Although chaining both perfectly in every fight is challenging, mastering this sequence ensures maximum damage output.

Execution Strategy

Casting Minimum Pain leaves you at one HP, so you must heal instantly to avoid death. Boss delay windows let you recover safely, but if you use a healing item at the wrong time, an enemy will kill you.

Timing your heels perfectly right after tripping a boss is important for staying alive and continuing to attack.

Parry Synergy

Incorporating parries into your play amplifies this build's effectiveness. Successfully parrying an enemy increases your spellcasting power and creates stagger opportunities, giving you precious seconds to heal and recast. If you're comfortable with parrying, you'll find that each perfect block protects you and fuels your devastating spell rotation.

Alternative Weapons

While testing with Red Deer demonstrates the build's potential, switching to Mercy once you reload your save will further elevate your damage due to its Spirit and Technique scaling.

You can also experiment with other high‑base‑damage weapons to complement stagger windows, but Mercy remains the optimal choice for sustained spellcasting synergy.

Tips and Recommendations

You should prioritize Spirit above all else, treating it as your primary stat rather than a secondary boost. Practice your parry timing relentlessly to generate stagger windows for healing and spell casting. Always carry healing consumables if you cannot reach a 120 % sync rate in a fight.

You can try out different weapons to find new damage combos and ways to play once you've mastered the core spell rotation.

If you pay attention to time, parries, and stat allocation, this atomic-level build will give you destructive power that no other build can match.
