The first installation in the Sky Dragon Biweekly Dungeon series! You can acquire 216i Red Skydragon, El Dorado, a high-damage ATK dragon. It's stronger than 004i Firedragon Tyrannos in the difficult late-game dungeons.


This dungeon has no Heart Orbs, and no way to recover HP. This raises the dungeon difficulty significantly. You need to carefully consider your moves so that every round deals damage, and clear out enemies that are about to attack if possible.

There are 10 battles in this dungeon, so take care to prep your skills before the boss battle. Due to lack of recovery, try to stall on early weak monsters, and be sure to keep an eye on HP.

The final boss 216i Red Skydragon, El Dorado attacks every round. Since there are no Heart Orbs, there are two strategies: either kill it quick before it kills you, or wear it down with an auto-healer.

All enemies are fire type in this dungeon, so water-type team members will make it easier to clear mobs.

Monster DataEdit

No. 216
Red Skydragon, El Dorado
216i No Evolution Needed
L. Skill
Dragon that specializes in ATK (highest in the game), but weak in other areas. Main skill is okay for clearing trash mobs, but impotent against high-defense bosses. Leader skill is not very useful due to many similar skills.
No. 399
Phoenix Resurrected
L. Skill
Phoenix has a special orb-enhancing skill that can further increase fire type burst damage. RCV is also unusually high among fire types, but keep in mind its HP is fairly low.

Sample StrategyEdit

This dungeon has no Heart Orbs for recovery, so you must pay attention to health. It's best to not use too many low-HP monsters (like Devils).

Below are some sample recommended monsters. (Not including 4x ATK team setups)

Team Makeup
Leader/Helper 122,123,142,211,139 122i123i142i211i139i
Core Sub 202,135,201 202i135i201i
Possible Subs 131,190,137,079,081,083,147,

Recommended strategy:

  • 4x Mono-color team + 202i Enchantress of the Sea, Siren. Use two same-type 2x ATK leaders, plus 202i Enchantress of the Sea, Siren for orb-changing recovery (preferably max-skill). Water type is most ideal for this team since the dungeon is all fire, and 202i Enchantress of the Sea, Siren is water type as well. This team has enough power output to clear out mobs easily, but you must work fast. This method is best for Expert/Int difficulty. Master rank is likely to get wiped due to the boss having too much HP to take down in time.
  • 50% resist + healer stall team. Use 122i Minerva, 123i War Deity Minerva, 142i Flamedragon Muspelheim, or 211i Meteor Volcano Dragon as leader to reduce damage by half, then add an auto-healer such as 139i Amaterasu Ohkami. This team will greatly increase your survivability, though it's lacking in damage output. Ideally other team members should be water type to increase damage. This method is suited for all difficulties, and won't have much trouble with Master rank.
  • 75% resist team. If you don't have good healer leaders, you could use a combination of 122i Minerva, 123i War Deity Minerva, 142i Flamedragon Muspelheim, or 211i Meteor Volcano Dragon as leader/helpers for a combined 75% damage resist. Use 202i Enchantress of the Sea, Siren for recovery, then bring three other strong attackers. Ideally you should bring water orb-changers like 101i Fenrir Knight or 221i Berserk to ensure damage output. This method is more suited for Master difficulty; not recommended for Expert/Int if you have the other team types because it takes more time.
