The entrance to Hell's Gates is located in the town of Byako. All RAIDS require you and any party member to be level 255.
It is advised to enter these RAID maps with a party due to the powerful mobs. The Hell Bovine mobs swarming hell deal high damage with attacks such as earthquake and heavens drive. But do not be fooled, they have powerful physical damage as well.
Most RAID maps require a specific sequence order to move further into the map and/or in order to summon the RAID bosses. It is recommended that you gather a party containing at least 1 TANK, 1 HEALER, 2 DPS, but this recommendation is not exactly required. Seek for hidden messages carved into the brimstone, and follow the advice of the spirits..
The required items to summon all RAID bosses are as follows : 7562 ( Ice Scale ) x1
7451 ( Fire Dragon Scale ) x1
7294 ( Turquoise ) x1
6091 ( Dark Red Scale ) x1
1250039 ( Poison Fourth Stone ) x1
1250038 ( Wind Fourth Stone ) x1
1250037 ( Ice Fourth Stone ) x1
1250036 ( Flame Fourth Stone ) x1
