Peroxide crystals modify skills, so their market depends on both supply and the current builds that can use each effect. Identify the exact displayed crystal, whether it is a normal or Ultimate variant, its inventory state, and its live effect before comparing trades. An attached modifier may not have the same trade state as an unused item.
The official Trello documents multiple Reiatsu Crystal roles and distinct Ultimate crystals, but balance and sources can change. Use the current description and interface for present behavior.
Identify type and state
Copy the full name, class, quantity, effect text, and any attached or locked state. Do not shorten every item to “crystal” in an offer. Normal crystals and Ultimate variants need separate records even when their names or themes sound related.
Confirm that the exact inventory object enters the supported trade window. If it is already attached to a move, do not promise transfer until the current interface shows that it is possible. Never drop a valuable crystal as a test.
Understand the current effect
Crystals can historically affect movement, resource use, burn, knockback, lifesteal, armor, delayed damage, pulling, chaining, anti-heal, mastery, or other skill behavior. Read the live tooltip and test on a suitable move. Only one modifier may apply to a skill under documented rules, so overwrite risk matters.
Record the benefit, drawback, compatible move types, and whether the effect scales with a build. A popular effect can have broad demand; a powerful but narrow effect may have fewer buyers and slower liquidity.
Check supply separately
Name the current source and eligibility, such as a mode, boss or raid, reward container, event, code, or shop only when verified. Add a date. Do not copy an old drop rate into a new value entry.
Supply can jump after an event, code, reward adjustment, or farming discovery. Keep source availability separate from price evidence. A theoretical scarcity label does not prove what buyers completed today.
Gather completed trades
Collect independent completed exchanges in a short observation window. Save exact names and quantities on both sides, remove duplicate posts, and distinguish ordinary sales from urgent quick sales, overpays, and friend trades. Listings are not completed outcomes.
Convert both sides into one named reference only when each component has a current value. Report a range, sample size, date, demand, liquidity, and confidence. If evidence is sparse or circular, leave the range unknown.
Compare build demand
Look at how many current builds use the effect and whether the crystal solves a common resource, movement, pressure, or survival problem. Do not use video views alone as demand. Track credible offers, completed time, and spread between buyers and sellers.
Balance changes can move build demand before trades settle. Keep pre-patch and post-patch observations separate, retest the tooltip, and wait for actual outcomes rather than guessing an immediate exact price.
Price Ultimate crystals independently
Ultimate crystals can have stronger effects and tradeoffs, so do not derive their value by multiplying a normal crystal. Verify the exact Ultimate name, present drawback, source, supply, compatible use, and completed trades. A rare Ultimate can still be illiquid.
For bundles, list each Ultimate separately and avoid counting slow components at their highest asking price. Compare the time needed to resell the bundle with the utility of keeping the crystal for your own build.
Trade without account risk
Use only the supported trade interface. Inspect names, variants, quantities and both sides after any change. Reject ground drops, trust trades, loans, imposed middlemen, off-platform payment promises, and artificial countdowns.
Never share Roblox cookies, passwords, one-time codes, backup codes, QR approvals, or screen control. Do not run a value checker, dupe script, executor, or extension sent by a trader. Leave any exchange that requires external verification.
Maintain the value record
Publish exact name, normal or Ultimate class, unused or attached state, current effect, source, tradeability, range, unit, window, sample size, demand, liquidity, confidence, and patch context. Use the Crystals guide for item mechanics and Updates for change signals.
Recheck after updates and preserve old snapshots with dates. A trustworthy crystal value page explains what was observed and what remains uncertain; it does not turn a thin market or one seller’s demand into permanent fact.
