Arena Caches

Arena Caches are Immortal Realm's scheduled public-PvP flashpoint — small, repeatable, time-and-place-known chest events on the shard's existing arenas. A single sealed cache spawns, players gather to fight or position over it, one player completes the claim and walks away with the loot. Clean ending, no unattended chest pile, no missed-event catch-up.

This page covers the three tiers, schedules, claim rules, rewards, and how the events fit alongside the rest of the shard's economy.

The three tiers

The three tiers share the same lifecycle but escalate in cadence, claim duration, despawn window, and reward weight. New Haven is the lower-stakes warm-up; Lost Lands Trammel is the medium contest; Lost Lands Felucca is the real-PvP version.

Lifecycle

Each event runs a fixed sequence:

1. Countdown — fifteen minutes before unlock, a shard-wide broadcast announces the upcoming opening. Five-minute and one-minute warnings follow.
2. Unlock — at the scheduled time, the system counts how many alive, non-staff, non-hidden players are standing inside the inner arena rectangle.
   • Zero players → the cache is withdrawn; no chest spawns; the next event is rescheduled. A shard-wide announcement says no challengers stood within the arena.
   • One or more → exactly one cache chest spawns at the arena center. A shard-wide announcement marks the release.
3. Contest — players gather, position, and (on Felucca) fight for control of the chest tile.
4. Claim — a player double-clicks the chest, holds still for the tier's claim duration, and on success receives a sealed reward bag.
5. End — chest deletes after a successful claim or after the despawn window expires. The next event is rescheduled. Account cooldown applies to successful claimants only.

There is exactly one active chest per arena at any time. Force-spawn commands (staff-only) refuse to create a duplicate. Server restarts never produce catch-up spawns; the next event resumes its normal cadence from the time of restart.

Claim rules

Double-clicking the chest starts a claim timer that cancels if any of the following happen:

• you move (any tile change)
• you take damage
• you die
• you become hidden
• you step outside the arena rectangle
• the chest is deleted (despawn, staff cancel)

On cancel the chest stays alive — another challenger can step in. The claim duration scales with tier: 2 seconds at New Haven, 4 at Lost Lands Trammel, 6 at Lost Lands Felucca. Felucca's longer window makes the contest a real PvP fight; the shorter Trammel windows make the contest about positioning, timing, and disrupting the active claimant by stacking onto their tile.

You can only start a claim if:

• you're alive, not hidden, not staff
• you're within interaction range of the chest
• you're standing inside the inner arena rectangle on the correct map
• nobody else is mid-claim (one claim attempt at a time)
• your account isn't on cooldown for that tier

Rewards

The body of every cache comes from the stock UO LootPack system — the same generation that drops on monster kills. Each tier uses a different pack tier:

This is real UO loot — magic weapons and armor with rolled properties, jewelry, reagents, gems, scrolls. Your character's Luck applies to the roll the same way it would on a creature kill, so a Luck-stacked claim pulls better magic-item properties.

On top of the stock body, the two Lost Lands tiers have a small jackpot chance — a curated artifact from a fixed allowlist:

Lost Lands Trammel jackpot pool (0.5% chance):

• Essence of Courage
• Spirit of the Totem (cosmetic mask)
• Hunter's Headdress (cosmetic mask)

Lost Lands Felucca jackpot pool (1% chance):

• Crimson Cincture
• Mace and Shield Glasses
• Folded Steel Glasses
• Wizard's Crystal Glasses
• Crystalline Ring
• Heart of the Lion
• Ring of the Vile
• Stormgrip
• Rune Beetle Carapace
• Kasa of the Rajin

Trammel jackpots lean cosmetic; Felucca jackpots lean toward real stat artifacts. Jackpots are independent of the main loot roll — when one fires, it adds to the cache, it doesn't replace anything.

Account cooldowns

Successful claimants enter an account-wide cooldown for the tier they claimed:

• New Haven: 12 hours
• Lost Lands Trammel: 18 hours
• Lost Lands Felucca: 24 hours

Cooldowns are per-tier and per-account. Claiming the New Haven cache does not block you from claiming a Lost Lands cache the same day; claiming on one character locks every other character on the same account out of that tier for the cooldown window. Cooldowns block claim attempts only — you can still attend, fight, and disrupt other claims while on cooldown.

Where to find live event status

Two surfaces tell you when the next cache opens:

• Shard-wide broadcasts — fired at 15-minute, 5-minute, 1-minute, and unlock thresholds. Watch your chat log around the cadence times for the tier you're hunting.
• Town Cryer NPC, Event Moderator tab — the EM tab now lists "Arena Caches — released now" (when a chest is up) and "Arena Caches — next openings" (the three tiers sorted by next-spawn time). It's a passive glance surface; no click-through. Same place the active and upcoming convoys are listed.

How Arena Caches fit in the broader shard

Arena Caches plug into existing systems rather than creating new currency or new economies:

• Loot is stock LootPack — the same drop generator your dungeon kills use. No new tier inflation, no new artifact economy.
• Jackpot artifacts are existing stock items drawn from the curated allowlists above. No new IRO-only craftables.
• Successful claims tick the Daily Ledger "Arena Cache" task on the days the daily roll seeds it (a 1-in-4 World-slot day). Three Time Tokens on completion.
• Cache events do not award PvP Tokens or Time Tokens directly — the cache itself is the reward.

Strategy notes

A few practical observations:

• New Haven is the warm-up. Twelve-hour account cooldown, two-second claim, modest loot. Newer players can show up, see how the cadence feels, and walk away with usable starter gear without committing to PvP.
• Lost Lands Trammel rewards positioning. No real combat, but the four-second claim is long enough that a competing player can disrupt by stepping onto the chest tile to interrupt with their presence. Coordinate with friends or pick off-peak event times for a cleaner claim.
• Felucca is the real version. Open combat, six-second claim, the best loot, and a 1% chance at a stat artifact. Bring a build that can hold ground for six seconds under fire — heavy armor, healing, and a friend running interference go a long way.
• No-show withdrawal is a real thing. If you're the only person hunting an event and you mistime arrival by a minute, the cache is gone. The 15/5/1-minute warnings give you ample notice; pay attention to the cadence.
• Cooldowns are forgiving across tiers. A 24h-cooldown Felucca claim doesn't block the same account from claiming Trammel or New Haven the same day. The three tiers run their cadences independently.

The system is small by design — three places, scheduled times, one cache, one claim, clean ending. It's meant as a public knot players can fall into during normal play, not a battleground framework or a content treadmill.
