Vulcanus / Hell
The Lava dungeon behind the Hell Gate in Katan — level 200 to enter, no quest line and no key, plus every drop and combination.
How to Enter
Level 200. That is the whole requirement — no quest line, no key, no difficulty to pick.
The way in is مدخل إلى زنزانة الجحيم, a warp gate standing at 115122, 59643 in أوروك. Step onto it at level 200 or above and it takes you straight down; below that it turns you away.
The materials for Lava Gear drop inside.
Drops
Monster drop table
Trash mobs and bosses drop the dungeon currency and loot box:
قطرة مورتاس 
صندوق شظايا الحمم
From the Lava Box
Opening a صندوق شظايا الحمم yields the elemental shards (plus a Typhon Shard):
شظية الحمم - جسدي 
شظية الحمم - سحري 
شظية الحمم - دفاع Typhon Shard
Combinations
The drops above combine into the crafting reagents used for Lava gear (see the Lava Gear guide for the exact recipes):
