EIP Gaming Build PlannervsMugen Monkey (Elden Ring)

If you play Elden Ring seriously and plan builds before spending Larval Tears, you'll end up in one of these two planners. EIP Build Planner is the modern tool with a complete UI and explicit Shadow of the Erdtree support. Mugen Monkey is the Souls community's classic planner (DS1 era) now extended to Elden Ring, specialized in optimizing the starting class for capped builds. The core difference isn't "which is better" — it's which problem you want to solve.

Coverage and data

EIP has complete base game + SOTE coverage updated to the latest patches. Every weapon, spell, talisman, Spirit Ash, Ash of War, and consumable is in the database. When Bandai releases a balance patch, EIP reflects changes within 1-2 weeks.

Mugen Monkey has complete base-game coverage but notable SOTE gaps. DLC-released items, especially rare weapons and Realm of Shadow talismans, can be missing or have outdated stats. For builds that depend on DLC gear, validating against EIP is needed.

This doesn't rule out Mugen — most PvP at level 125/150 still uses base-game weapons, where Mugen is complete.

Mugen's killer feature: the starting class optimizer

Mugen Monkey has a unique feature EIP doesn't implement: given a set of final stats (e.g., vigor 60, mind 16, end 30, str 70, dex 18, int 9, fai 25, arc 7), Mugen tells you exactly which starting class minimizes total level.

Why it matters: in capped PvP (typically 125 or 150), every level point counts. Starting as Wretch gives flexibility but low base stats; starting as Vagabond gives high base poise but some points get "trapped" if your build doesn't use fai. Mugen solves this mathematically.

EIP doesn't expose optimization; you have to manually try each class and compare resulting levels. For capped builds, this is a real disadvantage.

UX and iteration speed

EIP has the modern UI you'd expect in 2026: item cards, filtered search, gear visual preview, short animations, mobile responsive. Switching from one build to another is fast and items appear as clickable tiles.

Mugen is built in old-school wiki style: wide tables, dropdowns without search, no animations, no visual preview. It works — it's fast and predictable — but the experience is 2010s. If you'll spend hours iterating, EIP is less tiring.

For a quick build (10 min) both are acceptable; for long theorycrafting sessions, EIP wins on UX.

Sharing builds

EIP encodes the entire build in the URL: starting class, stats, gear slots, AoWs, spells, talismans, consumables. Copy-paste to Discord or Reddit works, and opening the URL elsewhere preserves the full state.

Mugen also encodes in URL but the format is more limited: stats and starting class always, weapons and armor sometimes, specific DLC talismans occasionally lost in the roundtrip. For sharing, EIP is more reliable.

Editorial coverage

Neither planner offers editorial guidance — no "this build is good for beginners" or "avoid this combo." They're mathematical tools.

For editorial advice, complement with Fextralife (Builds section), Mobalytics, or Powerbazinga videos. EIP and Mugen calculate; humans decide.

When each wins

Scenario	Best option
Capped PvP at 125/150 with stat min-maxing	Mugen Monkey
Build using SOTE DLC weapons	EIP
Low-level (30-60) twink build	Mugen Monkey
Fast iteration with modern UI	EIP
URL sharing with friends preserving full gear	EIP
Cross-game theorycrafting (DS3, Bloodborne, ER)	Mugen Monkey
Mobile reading while playing	EIP
Rare and datamined item coverage	EIP

Verdict

Use EIP if: your build includes SOTE content, you value modern UI, and you'll share builds via URL. It's the safe default for 80% of players.

Use Mugen Monkey if: you're optimizing for capped PvP and every level point counts. The starting class optimization feature is irreplaceable.

Ideally, use both. Do the first pass in Mugen to find the optimal class, then port the build to EIP to validate against the complete database and share. The planners aren't mutually exclusive — they're different stages of the workflow.
