Rhaegos, Lord of the Skies

Rhaegos is the final boss. He flies, he's immune to basically everything environmental, and he has 8 different attacks. Come prepared.

Stats

Summoning

The Rhaegos's Totem needs end-game materials, including drops from both previous bosses.

The Enchanted Flower comes from Emilya. The Purple Diamond is a rare end-game material.

Attacks and Abilities

Rhaegos cycles through several attack types in the air:

• Wind Gust: Blasts you backward. Stay grounded or brace with blocks.
• Lightning Strike: Calls lightning on your position. Keep moving.
• Icy Heart: Ice area attack that freezes and slows you.
• Swoop: Dives straight at you. Very fast, hard to dodge.
• Elemental Rage: Multiple elements at once. His scariest move.
• Random Dash: Unpredictable repositioning at high speed.
• Spawn Crystals: Periodically drops corrupt crystals around the arena. See the Crystal Mechanic below.

He also throws out frequent secondary attacks every few seconds: extra lightning bolts, wind streams (knock-up + damage), and frost auras (slow + damage over time).

Flight Patterns

Rhaegos circles an anchor point in the sky, varying radius and altitude as he swoops in for attacks and retreats back to the air. He almost never lands and is immune to most damage sources -- only Valrath's Staff reliably hurts him, so plan to deal all your damage with the staff.

Crystal Mechanic

Rhaegos periodically spawns corrupt crystals around the arena. Each crystal you destroy deals 50 damage to Rhaegos. Crystals don't despawn -- they wait for you, but you should destroy them ASAP because the bonus damage is the fastest way to chip down his 750 HP. Always prioritize crystals.

Health Milestone

At half health, Rhaegos gets faster and attacks more often. Be ready for the fight to ramp up hard.

Strategy

1. Keep moving. His attacks target your position. Standing still will get you killed.
2. Destroy crystals whenever they appear. This is how you actually win the fight.
3. Use Potion of Slow Falling to survive knockback from wind gusts and swoops.
4. Stay airborne with Super Jump Rune and ranged weapons -- Rhaegos rarely lands, so plan to fight him in the air.
5. Golden Grace Rune helps you survive the chaotic second phase.
6. Valrath's Staff can hit Rhaegos while he's flying.
7. Bring a Light Rune or torches. Rhaegos darkens the sky when he spawns.
