To beat the 11th Colossus you’re going to use a tool you’ve never used before and actually scare it away from its location.
Once again, you need to head north of the Shrine you start at and out over the stone bridge.
Where to find Colossus 11: Flame Guardian
Map location: F1
From here follow the tall stone bridge that dominates the skyline, and follow it north until you come to a crevasse cutting underneath it. To the right (east) you’ll see it widens out and there’s a zig zagging path all the way to the bottom. You’ll have to leave your horse and walk.
Swim across the water and you’ll see an entrance on the other side, up and to your right. It’s blocked with rubble, so instead go around to the right all the way until you enter a stone chamber.
You’ll need to jump over the big gap to land in the larger section of this chamber, but before you do note that there are four burning pots on pedestals. These are the secret to beating this Colossus.
This Colossus has two attacks. It will charge you like a bull, which you will have to quickly dodge-roll away from. It will also swipe at you with a claw. But its weakness is fire, and you’re going to use this to your advantage.
Jump over the gap and run to the closest pedestal. Climb it and wait for the Colossus to charge you. It will knock you to the floor, but also a smouldering stick. Grab it with your shoulder button and climb back up to light it.
You now have the upperhand, as the Colossus is afraid of fire. Wave it around in front of it and try to back it up towards the big opening looking out on the lake. Keep backing it up and it will fall down to the bottom, smashing its armour.
Don’t hang about – leap from the same spot and land on the Colossus, and gip on for dear life. It will get to its feet and run all the way back to the chamber.
Now you just need to swap to your sword and hit the single glowing weak spot on its back. Four hits should do it and it will collapse, earning you the Trophy: Guardian and the Pit.
