Citadel of Dimension

This is a Transcendence difficulty dungeon that was added to the Thai version where players (3 max) must race against time in order to acquire certain buffs and rewards. The recommended level was 61 (max level was still 60). This dungeon was open only from Saturday 6AM until Monday 6AM.

The main boss is a level 60 version of Nightmare (which is the boss for the level 54 Severam Fortress archdevil dungeon). Other archfiend (archdevil) bosses were supposed to be added in the future.

The 4 colored "asterisk" looking items in the possible rewards list were elemental crystals for upgrading resistance talisman cards (something that was removed for Trion at their request). The first item is an evolutionary stone that was a material utilized in evolving legendary (unique) gear by +1 once their growth XP reached 100%.

There are 5 mini-bosses that would give a player a buff if they were killed within 5 minutes. The buffs were comprised of increase critical damage, critical chance, increased penetration, increased penetration chance, and increased physical/magic attack.
