Murder Duels Cases are community documented as loot boxes that use a roulette-style reveal to award a random weapon skin from a Case-specific pool and rarity probability. Public pages also record Shop and code acquisition. Exact contents, price, availability, probabilities, duplicate behavior, and tradeability can change, so inspect the live Case before opening.
Currently documented Case index
These are known records, not the complete current Case catalog. The public value tracker also lists Case/Crate names, but a market row does not prove a Case can still be bought or opened.
Inspect the pool
Open the Case detail and record every displayed item and rarity. Check whether paired gun and knife entries are separate. If the interface can scroll, review the entire pool. Do not rely on a thumbnail or one rare highlight.
Compare the live pool with your collection. Count outcomes you would actually want. A Case can be poor for your goal even when it contains one excellent rare item.
Read probabilities
Use only probabilities displayed for that Case and current version. Rarity labels alone do not reveal drop rates. If no percentages are shown, keep the odds unknown. Do not copy rates from another Case, another duel game, or an old video.
Understand that several openings do not guarantee a rare result unless the live interface states a pity or guarantee system. No reliable public first-party pity rule was found for this page.
Decide whether to open
Compare the Case cost with a direct Shop item and a skill goal. Open when you enjoy the random result, accept common outcomes, understand duplicate handling, and can afford the opportunity cost. Save when you need a specific item, the pool is unclear, or spending would consume the full Coin reserve.
If the Case itself is tradable, decide whether keeping it offers more flexibility than opening. Once opened, a known inventory object becomes a random result.
Handle duplicates and tradeability
Before opening, find the current duplicate rule. Does the game keep another copy, convert it, or display another result? Public records do not establish the current answer. Check whether the Case and its rewards can be traded separately.
After opening, confirm the exact inventory name, type, rarity, and variant. A visual reveal is not enough for a later trade or catalog entry.
Get Cases safely
Community records name the Shop and codes as acquisition paths, with some historical lobby or event offers. Use the current official client. A code must be successfully redeemed and the Case must appear in inventory before it is called a reward.
Never buy an external “Case key,” install a verifier, or give account access. Robux purchases should use the official Roblox prompt. Coin purchases should show the new inventory or balance in the live game.
Common Case mistakes
- Treating a rarity name as a probability.
- Opening for one specific item without accepting other outcomes.
- Using a historical Case price or availability.
- Assuming paired gun and knife rewards arrive together.
- Ignoring duplicate behavior.
- Converting a community value into a guaranteed expected return.
What still needs live verification
The complete Case catalog, current sources, prices, pools, probabilities, pity rules, opening animation behavior, duplicates, tradeability, limited status, and regional purchase display require the current client. The known index provides search anchors while leaving unsupported fields unset.
