Urk Mountain
Map 100 in the Acheron region: 172 monsters of level 115 to 119, thirty fire traps that hit for 3,000 and Lord Silvester with 8 million health.
Updated on August 10, 2026Urk Mountain is map 100 and it is the busiest of Acheron's three neighbors: 172 common monsters, all with a 10 second respawn, spread across a mountain with narrow paths. It is also the only map in the region with a danger that is not a monster but scenery: the Flame Trap, fire traps planted in the ground.
At the top of the map stands Lord Silvester, a level 180 boss with 8 million health, a fixed point spawn and a 23 hour respawn. Access to the map asks for level 300, normal level, through the portal inside Acheron.

How to get there
- 1Move to Acheron
18,000 zen, level 380. You land in Acheron (58,195).
- 2Walk to 65,218
That is the Urk Mountain portal, in the south of Acheron.
- 3Step on the portal
It asks for level 300 and is free. You arrive in Urk Mountain (24,86).
- 4To go back
The portal at 19.87 returns you to Acheron (62,213).
Inside the map there are two pairs of internal teleports, all asking for level 300: (42,80) leads to (212,31) and comes back through (215,33), and (40,97) leads to (107,225) and comes back through (108,229). Without them, crossing the mountain on foot is long, because the map's three areas do not connect directly.

|---|---|---|---|---|---|---|
| Flame Trap | 80 | 1,000 | 2,500 to 3,000 | 1,400 | 30 | 10 s |
| Uruk Devil Fairy | 115 | 68,000 | 730 to 760 | 630 | 75 | 10 s |
| Uruk Elemental Beast | 117 | 75,000 | 770 to 800 | 650 | 50 | 10 s |
| Uruk Elemental Knight | 119 | 80,000 | 810 to 840 | 680 | 47 | 10 s |
| Lord Silvester | 180 | 8,000,000 | 5,000 to 6,000 | 1,400 | 1 | 23 h |
The Flame Trap deserves a paragraph of its own
The Flame Trap is level 80 with a thousand health, which sounds harmless, and it hits for 2,500 to 3,000, which is not. It is a destructible object, not a monster: it does not move, does not chase, gives no experience and drops nothing. Its attack range is 2 tiles and its field of view is 3, meaning it only reacts to whoever gets close.
There are thirty of them scattered along the mountain corridors and the respawn is 10 seconds, so breaking one to get past does not solve anything for long. The practical rule is simple: go around, do not fight. A character who enters Urk Mountain on low health and walks over two traps in a row dies without having seen a monster.
Lord Silvester
Lord Silvester is a map boss, not a scheduled event. He spawns on his own at a fixed point between (124,105) and (130,114), at full health, and comes back 23 hours after dying. There is no trigger, ticket or summoning for him: whoever gets there first after the respawn finds the boss waiting.
- ApproachField of view of 12 tiles
He sees far and he is aggressive. There is no cutting through his area unnoticed.
- RangeAttacks from 6 tiles away
Attack range of 6 with movement of 5, so running backwards does not easily take you out of range.
- During the fightEight million health straight through
He has no phases, does not heal and does not summon escorts. It is pure damage on both sides, with 1,400 defense and a defense rate of 4,800.
- Afterward23 hours until the next one
The drop is the server standard for a monster of that level, with no exclusive table.
What drops here
The four global groups, with nothing exclusive: zen on half the kills, random item on 30%, jewel at 0.1% and excellent at 0.01%, the last two applying across the whole map because every monster here is past level 76. The Flame Trap is the exception that drops nothing, since it is a destructible object and not a monster.
Until recently nothing dropped in Urk Mountain, not even zen: the map was registered with the medal groups only and no monster here fits the medal range, so every roll came out empty. That has been fixed.
Is it worth it?
- 172 monsters of level 115 to 119, the highest concentration in the Acheron region.
- An 8 million health boss reachable with no ticket, no schedule and no mandatory party.
- Level 300 to enter, well before endgame.
- A map practically empty of players, because it does not exist on an ordinary Season 6 server.
- The 30 Flame Traps turn careless movement into death.
- No exclusive drop. What comes out is the same as on any map in the bracket.
- No vault NPC and no direct Move: every trip goes through Acheron.
- Silvester has a 23 hour respawn, so you cannot repeat the fight the same day.
