Time Compression

After Adel falls and you regain control, save your game.

Run through the multiplying Save Points and exit.

You will face the first of eleven Sorceresses.

Lesser Sorceress (x6): These Sorceresses have 3,390 HP and use weak elemental spells. They can be mugged for Meteor Stone or Ultima Stone and drop Flare Stone, Holy Stone, Meteor Stone, or Ultima Stone. They are vulnerable to status effects.

After defeating the first six, a new variety appears.

Veteran Sorceress (x4): These have 4,496 HP. Tactics vary: the first uses Double then Thundaga, the second uses Meltdown, Quake, and physical attacks, the third uses Meteor, and the fourth uses Flare. They can be mugged for Meteor Stone or Ultima Stone and drop Flare Stone, Holy Stone, Meteor Stone, or Ultima Stone.

After defeating these four, the final Sorceress appears.

Master Sorceress: This Sorceress has 34,120 HP and is immune to most status effects. She uses Ultima (which deals over 1,000 damage even with Auto-Shell) and a powerful melee attack. She can be drawn for Flare and Holy, and mugged for Meteor Stone or Ultima Stone. She drops Flare Stone, Holy Stone, Meteor Stone, or Ultima Stone.

Use Aura and limit breaks to defeat the Master Sorceress.

After the fight, you will be in the courtyard of Edea's House. Enter the house, go to the beach, and proceed forward.

A scene will reveal Ultimecia's castle. Before entering, you need to recover the Ragnarok.

Head left, then down towards Ultimecia's Castle.

On the next screen, find a Triple draw point near dead SeeDs.

Continue to a massive chain, run across it, and enter the middle glowing portal.

You will emerge on the Centra continent. Find the Ragnarok, a flashing red dot to the southeast on the world map.

To reach the Ragnarok, follow the coast west and north to some mountains, then go around them west to find the Nectar Peninsula Chocobo Forest.
