Where Do Crystals Come From? The F2P Free Resource Guide

Quick answer: The seven main free sources F2P players use to stockpile NTE’s gacha currency, Crystals (160 Crystals per pull), are: redeem codes, daily activity, the main and side story, the achievement system, limited-time events, exploration chests, and mail compensation. See the full breakdown below.

Crystals are the main currency for pulling in NTE. This article covers every free source F2P and low-spend players can use to steadily stockpile Crystals, so that every pull counts for more.

What Are Crystals

Crystals are the main currency used to pull on the character banners and the Arc banners. They cannot drop directly from combat — they come from quests, events, and system rewards. That is why, for F2P players, the most important habit is to never miss a single free source.

The Seven Free Sources

1. Redeem Codes

Serial codes the developers hand out from time to time. Enter one and you get Crystals instantly — the easiest source of all. Our redeem codes page is kept updated with currently valid codes — codes usually have a very short window, so redeem them as soon as you see one before they expire.

2. Daily Activity and Daily Quests

Complete daily quests each day to build up activity points, and claim the rewards (which include Crystals) once you hit the threshold. This is the most reliable long-term source — spend a few minutes clearing it every day.

3. The Main and Side Story

Pushing the main story not only unlocks system features; the chapter rewards along the way also include a significant amount of Crystals. In the early game, pushing the main story forward is the fastest first windfall.

4. The Achievement System

Completing combat, exploration, collection, and other achievement categories grants Crystals. Many achievements are earned naturally during normal play, so remember to return to the achievement menu periodically to claim them.

5. Limited-Time Events

Patch events are usually the richest source of “one-time resources,” often handing out large amounts of Crystals at once and sometimes even a free character. Be sure to take part in every launch and every patch event.

6. Exploration and Chests

Chests, puzzles, and hidden spots across the open-world map also grant gacha resources — just collect them as you pass by.

7. Mail Compensation

Official maintenance, event payouts, and community milestones often deliver compensation through the in-game mailbox. Mail has a claim deadline, so remember to clear your mailbox regularly.

Spend Your Resources Where They Count

Once you have saved up Crystals, do not rush to pull randomly:

• In NTE the limited banner never loses the 50/50, and your pity count even carries over between limited banners, so it rewards focusing your pulls on a target character. For the mechanics in detail, see the complete gacha pity mechanics breakdown.
• Before you pull, use the pull planner calculator to estimate whether you have enough pulls on hand to reach pity.
• When resources are tight, prioritize filling a role your team is missing rather than duplicate strong characters. For the recommended order of investment, see character build priority.
