Quick answer: Weakened stone walls need the Tiger Cannon, your reward for beating Lei Dang in the Mirage Estate. It works even when not equipped. One Crimson Manor wall opens with a Powderkeg instead.
Stone walls: Tiger Cannon
Head to the Mirage Estate. Lei Dang, the Tiger Cannon, is roughly 66 m away from the Perfect Vessel Pond bell and 11 m higher.
Continue along the story objective until it leads you to a weakened wall. The objective reads: “Continue until you find a wall you can blast open”.
Blast the wall open. The objective then changes to “Blast through the wall with the Tiger Cannon”, and the stone shatters to clear the path.
Until you beat him, weakened stone walls stay closed.
The wall under the Valley Sha-Chi Tower
The Crimson Manor quest has its own broken wall, beneath the Valley Sha-Chi Tower. You open that one with a Powderkeg.
Other barriers
Some obstacles look like walls but need a different tool. Use this table to match each blocker to what clears it.
| Barrier | What clears it |
|---|---|
| Weakened stone walls | Tiger Cannon |
| Broken wall beneath the Valley Sha-Chi Tower | Powderkeg |
| Wooden planks over sealed ground | Bashpole |
| Chain Barrier | Dread Axe |
| Brambles | Flaming Mane |
| Flames | You Loong’s Deluge |
The Chain Barrier comes with its own objective, which reads “Break the Chain Barrier with the Dread Axe and continue on”.
