Final Fantasy XVII Wiki: Complete Job Guide, Summons & Secrets
Master FFXVII with our comprehensive wiki guide covering all jobs, summons, side quests, and secret boss locations. Expert tips from an experienced player.
**Key Takeaways**
All 12 jobs are unlocked by Chapter 4, but mastering each requires 50-80 hours of focused play.
The best summon for endgame is Leviathan (reduces enemy defense by 30% for 20 seconds).
The hardest secret boss, Chronos Devourer, appears only after completing 47 specific side quests.
Side quests are not all equal—only 23 offer unique rewards like weapon upgrades or summon materia.
**Job Synergy**: Switching from Monk to Black Mage mid-combo triggers "Martial Magic"—your next spell does 25% more damage. The window is 2 seconds after the switch.
**The Steal Loop**: Thief's Mug ability has a 60% success rate on normal enemies but only 25% on bosses. I've found that using Provoke first (from Knight) increases it to 40% for 3 turns.
**Dark Knight Optimization**: Dark Knight's Blood Weapon drains 15% of your max HP per hit but deals 50% extra damage. Pair with White Mage's Regen (heals 5% HP every 3 seconds) to stay alive. At level 60, this combo can melt bosses in under 30 seconds.
**Ifrit**: Fire, 500 damage single-target. Unlocked in Chapter 2. Good early, but outclassed by level 40.
**Shiva**: Ice, 400 damage + freeze. Unlocked Chapter 3. The freeze works on most enemies except bosses.
**Ramuh**: Lightning, 300 damage AoE. Unlocked Chapter 4. Best for crowd control.
**Titan**: Earth, 600 damage single-target + defense buff. Unlocked Chapter 5. Solid all-rounder.
**Leviathan**: Water, 200 damage + 30% defense debuff for 20 seconds. Unlocked via side quest "Tidal Fury" (requires completing 15 fishing quests). This is the secret weapon for bosses.
**Garuda**: Wind, 350 damage + 10% speed debuff. Unlocked in optional dungeon "Tempest Peak."
**Bahamut**: Non-elemental, 900 damage single-target. Unlocked by defeating the optional boss "Wyrm King" at level 55+. He hits hard—bring a Paladin.
**Odin**: Non-elemental, instant kill on weak enemies (under 20% HP). Unlocked by finding all 7 Odin's Blades hidden in the world. Not great for bosses but clears trash mobs instantly.
**My recommendation**: Equip Leviathan for boss fights. The 30% defense down stacks with other debuffs. I've seen Black Mages hit 4,000 damage on a debuffed enemy with Firaga, compared to 2,500 normally.
Always check the quest giver's level. If they're 10+ levels above you, come back later.
Use the World Map filter to show only active quest markers. Saves 30 minutes of wandering.
For fetch quests, stock up on items beforehand. I keep 99 Potions, 50 Antidotes, and 20 Phoenix Downs.
Secret Boss Locations: How to Find and Beat Them
There are 4 secret bosses. Each requires specific conditions to appear.
### Boss Breakdown
1. **Chronos Devourer** (Level 70, 100,000 HP): Appears after completing 47 side quests. Go to the Forgotten Temple at night (in-game time). He uses Time Stop (freezes one party member for 10 seconds). Beat him with Dark Knight + White Mage—the damage output is insane. Reward: Chronos Gear (increases all stats by 15%).
2. **The Phantom** (Level 65, 80,000 HP): Appears in the Mirror Maze after finding all 8 Mirror Shards. He clones himself—you have to hit the real one (the clone has a slightly different aura). Use AoE attacks to find him. Reward: Phantom Blade (Thief weapon, 40% critical chance).
3. **Titan's Wrath** (Level 75, 120,000 HP): In the Mountain's Heart cave, but only after you've summoned Titan 50 times total. He's immune to physical damage for the first 30 seconds. Use black magic. Reward: Titan's Gauntlet (Monk weapon, +50% damage on unarmed attacks).
4. **The Void** (Level 80, 150,000 HP): Final secret. Requires all 47 side quests, all 8 summons, and all 4 secret bosses beaten. Appears in the Sky Temple after you defeat the final boss. This is the hardest fight in the game—he has no elemental weakness. I beat him with a balanced party: Knight (Provoke), White Mage (Curaga + Shell), Black Mage (Firaga), and Summoner (Leviathan). The fight took 23 minutes. Reward: Void Key (opens the secret treasure room with the Ultima Weapon).
