Star Wars Jedi: Fallen Order: Star Wars Jedi: Fallen Order 100% Completion Guide

The Mantis sets down on Ilum by itself. This trip covers the whole planet: 5 chests and 7 Force Echoes, 3 of them Secrets. Cal has every ability the walk needs, but no working lightsaber yet, so he has no blade to fight with or to cut ice. That matters little on the way in, because nothing but a few Probe Droids attacks before the Workbench. Everything that needs a blade is left for the way out: the ice in the Crystal Caves and the chest at the top of the Temple wall. Nothing is left for a later trip. If you still carry Terrarium Seeds, plant them before you walk down the ramp.

To the Temple wall. Go through the arch and walk into the wind to a second arch and a dead end. On the left, a narrow gap in the ice lets Cal squeeze through to a view over the mountains. Turn left, go up and around the climbing wall to the ledge above, and walk on to the huge claw wall on the face of the Temple. Climb it, crossing from side to side over the gap in the middle. Don't go to the top yet: the chest up there needs the new lightsaber, and this walk climbs back up for it. About halfway up, step off onto a ledge on your left and follow it round into a small room.

The light puzzle, first beam. In that room, Force Pull the rope off its wall reel and lock it into the anchor beside it. A big hatch opens and stays open: Wall Run the ridged wall through it. Past a short room, the great round hall opens up. Drop to the slightly lower level on the right, where a window and a second rope reel sit, and turn to face the middle. A big crystal hangs from the ceiling with a rope under it, a swivel arm stands on the far side, and two doors are frozen shut: a small one across the hall and a giant one down on the floor. Force Pull the arm over to you, then Force Pull the rope from the reel behind you and clip it to the arm. The window opens, and its beam just misses the crystal. Force Pull the crystal's rope and back towards the window until the crystal swings into the beam, which melts the small door.

Set the crystal. Still holding that rope, swing across to the ledge of the melted door and turn round. Force Pull the arm to your side, which frees the window rope. Force Pull the crystal's rope again, clip it to the arm, and Force Push the arm back across the hall. The crystal now hangs where the last window needs it.

Into the Crystal Caves. Swim to the far end of the water and climb the wall there; the caves start a few steps on. Wall Run right along the ridged wall.

Follow the path on from the Wall Run, balancing along a narrow beam to solid ground.

Slide down the next stretch of ice and use the Wall Run at its end to reach a climbing wall. At the top is an island with a large hole in it, a Meditation Point and two Jedi statues.

Into the Imperial Trench. From here the fighting starts. Cut the icicles by the Workbench and every ice barrier after them until you step out of the cave among Scout Troopers. A transport drops two more groups, and Force Push can send them off the platform. Then BD-1 can Slice the door on the right, which opens onto a room full of Security Droids. Getting close wakes the whole room, so draw them out one at a time.

Back to the island. Go through that door, cross the Security Droid room and swing back over the rope to the Imperial Trench Meditation Point. Cut the barrier behind it and jump across to the Scout Troopers on guard. Cross the long pool you dived into earlier and drop to the level below, where Stormtroopers and Scout Troopers wait. Clear them and slide down the ice to the island with the large hole and the Meditation Point. Go between the two Jedi statues again: Scout Troopers and a Security Droid now hold the tunnel cave.

Back to the Temple. Cross the next small island to the climbing wall after it and keep to the right side of the caves until you are back near the big ice slope. From there the way out is a single path, and Scout Troopers, Purge Troopers and Security Droids hold it in groups, with a rocket trooper near the last Wall Run. Swim the water and climb to the Jedi Temple Meditation Point. In the great hall, troopers blast open the sealed main entrance: beat them, rest at the Meditation Point behind you, and leave through the blasted door onto the Shattered Lake.
