Endfield Gacha Simulator

What Is a Gacha Simulator?

A gacha simulator is a tool that replicates the character summoning mechanics found in gacha-based games. This simulator isnot connected to official Endfield servers and does not interact with real player accounts.

Its purpose is to provide a realistic and transparent overview of pull probabilities, helping players understand how systems like pity, rate-up, and spark actually work over time.

Character Rarity System

• 6★ Operators — Highest rarity with very low base odds
• 5★ Operators — Mid-to-high rarity units
• 4★ Operators — Common units

All pull rates and rarity distributions are modeled after the official Arknights: Endfield systems, ensuring accurate long-term simulation results rather than misleading single-pull outcomes.

Pity, Spark & Banner Mechanics

Unlike many modern gacha games, Arknights: Endfield does not use a traditional 50/50 guarantee system. While featured Operators have a 50% appearance rate when pulling a 6★, failing to obtain them does not guarantee success on the next 6★.

• 5★ Guarantee — At least one 5★ or higher every 10 pulls
• 6★ Pity — A 6★ Operator is guaranteed within 80 pulls
• Soft Pity — After 65 pulls, 6★ probability increases by 5% per pull
• Spark System — Featured 6★ guaranteed at 120 pulls (once per banner)

Pity only carries over up to 80 pulls. Progress beyond that will not transfer to future banners. Spark counters are banner-specific and do not carry over.

Beginner Banner: New Horizons Headhunting

The Beginner Banner is designed to help new players build their first roster. Pulls can only be done in multi-pulls usingNew Horizons Headhunting x10 Permits, obtained through main story progression.

• Only multi-pulls (10x) are allowed
• A 6★ Operator is guaranteed within 40 pulls
• Only a fixed pool of 6★ Operators is available
• Pulling a 6★ early does not reset or re-trigger the guarantee

Pull Analysis & Luck Evaluation

Each simulation includes a statistical breakdown of your results, helping you evaluate whether your pulls are above or below expected averages.

• Average 6★ pity count
• Featured vs non-featured 6★ ratio
• Overall rarity distribution

The analysis is purely informational and does not predict future pulls. It is designed to promote realistic expectations and responsible understanding of gacha systems.
