This is not the only problem, though, because there are two suits of armor here.
One of them is armed with a spear, whereas the other one wields magic.
In here, there is a chain that ids connected with the puzzle here.
It may be a bit troublesome to figure out what to do, so take the following steps.
Grab on to the chain, by holding down Circle button (do not climb up the chain!)
and run towards the wall first.
Now, turn back and start running in the opposite direction, i.e.
to the spot in which you entered this chamber.
Quickly, climb up the chain a bit and lean back.
Allow Trico to deal with suits of armor.
Remember to soothe him down after the battle.
Return to the chain.
This time, do not move it and climb up over it.
Reach the balcony up above.
There, you find abarrelthat you’re able to toss to Trico.
Here, you might walk over the damaged railway.
Take the first left turn and get down.
There, you find a lever that it’s possible for you to use to unblock the gate.
As a result of that action, Trico will be able to rejoin you.
