This is a one-time visit, make sure you collect all bestiary entries and treasures.
With your airship upgraded, it'll give you an option to go up or down when you try to disembark. Choose up to go to Ronka Ruins.
Before you can enter, you'll have to fight 4 mini-bosses and 1 boss.
First, approach the cannons on both sides to initiate the battles. There are 2 cannons (2 battles) on each side:
Outer Cannons: Flame Thrower x2 (Guaranteed Drop: Speed Shake)
Inner Cannons: Rocket Launcher x2 (Guaranteed Drop: Iron Draft)
These cannons are weak against thunder-based magic. Lightning Scroll (Ninja) seems to deal the highest damage among other magic. These cannons are destroyed with just 2 Lightning Scroll. Ramuh and Thundara are great too. After the cutscene, heal up and quicksave before approaching the cannon in the middle for a boss fight.
Boss: Soul Cannon, Launcher x2
Guaranteed Drop: Dark Matter, Hi-Potion x2 (Launcher)
Your first priority is to destroy the 2 Launcher as quickly as possible.
The Launcher is vulnerable to Level 5 Death, so having 1 Blue Mage in your team will speed up the battle fast.
Throw all your thunder-based magic on the boss: Lightning Scroll, Ramuh, Thundara, Thundara Spellblade, or breaking Thunder Rod.
Enter Ronka Ruins.
There are 3 blue magic spells in this dungeon, one of them is another Level-based magic Level 4 Graviga, which can only be obtained when your character level is divisible by 4.
Your levels are most likely between 20 and 24, so take time and farm your level here until your level is at 20, 24, or 28, etc.
Setup: 1 ally with Control, 3 allies with Learn ability.
Blue Magic (19/30): White Wind
From Enchanted Fan
Commonly spawns on 3F. You'll have to control it first and use the spell on your party.
Blue Magic (20/30): 1000 Needles
From Lamia
Commonly spawns on 3F and 4F. Requires Control and cast it on your ally with Learn ability.
Blue Magic (21/30): Level 4 Graviga
From Ghidra
It's a rare spawn on 5F, but more common in the room with 2 chests.
Make sure you have at least 1 member with a character level divisible by 4 (20 or 24) and equipped with Learn ability.
Ghidra will only cast Level 4 Graviga upon death. The thing about this guy is it's super strong and starts with Auto-Reflect, so any magic cast on it will reflect back at you. Luckily, it's an Undead type monster, so we can exploit its weakness by throwing Phoenix Down to instantly kill it.
Bestiary Checklist:
Item Checklist:
- C-070: Golden Armor
- C-071: Elixir
- C-072: Phoenix Down
- C-073: Golden Shield
For the upcoming boss, Blue Mage is highly recommended. Black Mage and Summoner should be used with caution because the boss has 5 forms, each with different elemental weaknesses and immunities. The last form is immune to all elements.
If you happen to have Dark Bow (dropped by Enchanted Fan), it can deal decent damage to the boss.
Item Checklist:
- C-074: Hi-Potion
- C-075: 5000 gil
- C-076: Shuriken
- C-077: Ancient Sword
- C-078: Moonring Blade
- C-079: Power Armlet
- C-080: Cottage
- C-081: Ether
Boss: Archeoaevis
Guaranteed Drop: Goliath Tonic
The easiest strategy is to use Flash and spam 1000 Needles (with 3 Blue Mages and 1 White Mage) until the final phase.
The final form Revived is vulnerable to Level 5 Death.
Unfortunately, physical attacks deal little damage to it.
