Among the many high-level sorceries in Elden Ring, Ranni's Twin Moon stands as one of the most visually striking and Elden Ring Runes mechanically demanding spells in the game. Introduced with the Shadow of the Erdtree expansion, this legendary sorcery represents the culmination of lunar magic tied to Ranni the Witch. While devastating in the right hands, it requires careful positioning, timing, and build investment to use effectively. Understanding how Ranni's Twin Moon works-and how to build around it-can turn it into a boss-melting centerpiece of a late-game Intelligence build.

What Is Ranni's Twin Moon?

Ranni's Twin Moon is a legendary Intelligence-based sorcery that conjures two massive dark moons which descend in sequence toward the target area. Each moon explodes on impact, dealing heavy magic damage, inflicting Frostbite buildup, and briefly suppressing enemy magic negation, making subsequent hits even more lethal.

Unlike fast-casting Glintstone spells, Ranni's Twin Moon is a high-commitment cast. It consumes a large amount of FP and has a long wind-up, but in exchange delivers enormous area damage and crowd control potential. This makes it ideal for bosses, large enemies, and tightly grouped foes rather than fast-moving trash mobs.

Requirements and Optimal Build

To use Ranni's Twin Moon effectively, your character must be heavily invested in Intelligence. The spell demands a very high Intelligence stat, placing it firmly in the late-game category. Most players will want at least 70–80 Intelligence to justify the FP cost and maximize damage scaling.

The best staffs for this sorcery include:

Carian Regal Scepter, which boosts full moon sorceries

Lusat's Glintstone Staff, for raw damage at the cost of increased FP consumption

Talismans that synergize well include the Graven-Mass Talisman for sorcery damage, Radagon Icon to shorten casting time, and FP-management options like the Cerulean Amber Medallion.

How to Cast and Position Correctly

Positioning is the most important factor when using Ranni's Twin Moon. Because of its long casting animation, you must create a safe window before committing.

The ideal moments to cast are:

After a boss finishes a long attack animation

When an enemy is locked into a slow recovery phase

At medium range, where enemies are less likely to interrupt you

Once cast, the first moon strikes and applies Frostbite buildup and magic resistance reduction. The second moon follows shortly after, capitalizing on the debuff to deal even more damage. This sequencing is what makes the spell so lethal-landing both moons is critical.

PvE and Boss Strategies

In PvE, Ranni's Twin Moon excels against large or stationary targets. Dragons, giants, and late-game bosses with predictable patterns are especially vulnerable. Casting it at the start of a fight can instantly swing momentum in your favor, chunking a massive portion of a boss's health bar.

Against groups, the spell's wide area of effect can clear clustered enemies, but the long cast time makes it risky unless you've already created space or used Spirit Ashes to draw aggro.

PvP Considerations

In PvP, Ranni's Twin Moon is more situational but still powerful. Skilled opponents can dodge it if cast carelessly, but using it as a pressure tool-forcing rolls or controlling space-can be effective. Casting after a knockdown, during a heal attempt, or in narrow terrain increases your chances of landing both moons.

Final Thoughts

Ranni's Twin Moon is not a spell for reckless casting. It rewards patience, planning, and buy Elden Ring Runes mastery of enemy behavior. When used correctly, it embodies the fantasy of high-level sorcery in Elden Ring: slow, deliberate, and utterly devastating. For Intelligence-focused Tarnished willing to commit to its demands, Ranni's Twin Moon is one of the most satisfying and powerful spells in the Lands Between.
