Full Stat Table
Everything the server file records for each monster on this map.
| Monster | Lv | HP | Damage | Def | M.Def | Atk rate | Block | Range | Respawn | Spawns |
|---|---|---|---|---|---|---|---|---|---|---|
| Deep Dungeon Chief Skeleton | 250 | 801,970 | 3891–3991 | 2548 | 2293 | 3550 | 1190 | 5 | 10s | 31 |
| Deep Dungeon Hell Spider | 250 | 789,632 | 4090–4190 | 2608 | 2347 | 3100 | 1120 | 4 | 10s | 90 |
| Deep Dungeon Thunder Lich | 275 | 999,378 | 4525–4625 | 2877 | 2589 | 3650 | 1223 | 4 | 10s | 27 |
Deep Dungeon Thunder Lich has the most health here at 999,378, and Deep Dungeon Thunder Lich hits hardest at up to 4625 damage. The most common spawn is Deep Dungeon Hell Spider with 90 spawn points of the 148 on the map.
Best Target for Experience
The server stores an ExpLevel per monster, which drives the experience it awards. Dividing that by health gives you experience per point of damage you have to deal — the number that actually decides where you stand and grind.
| Monster | Lv | Exp value | HP | Exp per 1,000 HP | Spawns |
|---|---|---|---|---|---|
| Deep Dungeon Chief Skeleton | 250 | 818 | 801,970 | 1.0 | 31 |
| Deep Dungeon Hell Spider | 250 | 754 | 789,632 | 1.0 | 90 |
| Deep Dungeon Thunder Lich | 275 | 778 | 999,378 | 0.8 | 27 |
Deep Dungeon Chief Skeleton is the most efficient kill on this map at 1.0 exp per 1,000 HP — 1.3x better than Deep Dungeon Thunder Lich at 0.8. With 31 spawn points it is also easy to find.
Read this as a ranking, not as absolute numbers. Almost every private server rewrites experience rates, so the exp values here are the unmodified Season 21 baselines. The order of the table survives most rate changes; the raw figures will not match your server.
Elemental Resistances
No monster on DeepDungeon 4 carries any elemental resistance — every one of them takes full ice, poison, lightning and fire damage. That makes it a clean map for testing elemental builds.
Drop Tables – Straight From the Server Files
Each monster rolls its own item bag. The tables below show every entry in that bag and its share of the bag — the chance of getting that item when the monster drops an item from its bag at all.
How a drop is decided on this configuration — each kill rolls one wheel: about 29.8% of kills hit the monster’s own bag below, 6.0% the shared rare pool further down, 10.0% a zen bundle, and roughly 50% drop nothing. Other servers retune these bands — the bag shares are the part that carries over.
