Legion Mythic Dungeons: Weekly Chest at Mythic+ 16-18 (EU)

A Legion mythic dungeons boost at keystone levels 16 to 18 is a group run where a high-level team clears the dungeons while you collect the weekly chest reward. This page explains what that chest holds, how long the runs take and what to watch for before you join one on an EU realm.

How the Legion Mythic+ Weekly Chest Works

The weekly chest opens after you complete at least one Mythic+ dungeon in the previous reset week. Its loot depends on the highest keystone you finished. A +16 to +18 key sits in the upper-middle of the Legion range, so the chest is a solid piece of gear, not a jackpot.

Reset on EU servers happens on Wednesday morning. Anything you complete before then counts toward the chest that opens after it.

You get one item per week. That is the main limit on any gearing plan built around Legion Mythic+, and it is why people care about which key level they log.

What to expect from the loot

Expect one piece of gear at the item level tied to your best key. Legion drops are random within your class and specialization pool, so two weeks of identical runs can give very different results. Do not plan around a specific slot.

Legion Mythic+ Keystones 16 to 18: Time and Difficulty

At these levels the dungeons are no longer forgiving. Enemy health and damage scale hard, and affixes such as Fortified, Tyrannical, Bolstering and Necrotic punish sloppy pulls. A well-geared group still finishes most dungeons in about 25 to 35 minutes.

The timer matters. Finishing in time upgrades the keystone and improves the chest tier. A depleted key still counts as a completion, but you lose the upgrade.

• +16: the entry point for the stronger weekly chest tier
• +17: a small step up in enemy scaling
• +18: the hardest of the three, with the least room for deaths

Is a Legion Mythic Dungeons Boost Worth It?

It depends on what you need. If your goal is a single weekly item and you lack the time to assemble a group that can time a +16, a boost saves real hours. If you enjoy the dungeons themselves, running them with friends is cheaper and teaches you the routes.

Prices vary a lot between sellers, and a typical range for a one-key chest run is roughly 10 to 40 euros depending on level and bundled extras. Treat that as a rough guide only. My advice: avoid anything far below that range, since it usually means rushed or unreliable runs.

Self-play versus traded runs

In a self-play run you are on your own character and fight alongside the team, and the chest tied to your own completion is yours. In a trade-style run the loot is moved to you afterward. The second format has more restrictions, so read the rules about tradable items before you commit to either.

Gear and Collectibles Worth Chasing in Legion

The chest is only one source. Raid bosses, world content and older expansions feed the same collector habits. Players who like old-content runs often pair Legion keys with other farms, such as the mummified raptor skull mount from Battle for Azeroth dungeons.

If your goal is full sets rather than one weekly item, look at raid-based plans. Many players looking for mythic uldir gear or who want to buy mythic antorus runs do so to fill slots the chest never reaches. Each of those gives a more targeted route than waiting on a random weekly roll.

Before You Join Any Run

Check a few things first. They take five minutes and prevent most bad experiences.

• Your class and specialization are supported by the group
• The key level matches the chest tier you want
• Rules on loot trading and timing are stated clearly
• You have not already used the weekly chest on this character

Never share your account login with anyone. A legitimate run needs only your character name and a party invite, nothing more.

Frequently Asked Questions

How many Legion Mythic+ dungeons do I need for the weekly chest?

One completed Mythic+ dungeon is enough to open the chest. Your best key of the week decides the item level. Running more dungeons does not add extra items.

Does a depleted key still count for the weekly chest?

Yes, finishing after the timer still counts as a completion. The key simply does not upgrade. Timing it is better because the higher level can raise your reward.

When does the weekly chest reset on EU servers?

The weekly reset on EU realms happens on Wednesday morning. Runs finished before that moment count for the chest you open after it. Anything done afterward belongs to the next week.

Can I pick the item that drops from the chest?

No, the item is random within what your class and specialization can use. Some weeks give a clear upgrade and others little. That variance is normal in Legion.

Is it safe to use a Legion mythic dungeons boost?

Boosting carries some risk, since it can go against the game's terms of service. Reduce it by never giving out login details and by sticking to party-based runs. If a seller asks for your password, walk away.
