You'll need The Banyan's Heart in Phantom Blade Zero to unlock certain skills like Fluid Form Level 2, Quick Remedy, or Opening Strike.

You can get your first Banyan Heart towards the end of the Crimson Forest area, just after you activate the Parting Mists bell, after you fight Stone Fist Iron Fever—it's basically impossible to miss:

Drop down from the Parting Mists bell and head across to the island with the tree directly ahead of you.

Interact with it to be transported into The Banyan Tree's trial realm.

You'll have to defeat three waves of enemies, culminating in Jing Ye, the bleed bandit boss from earlier in the Crimson Forest. Similar to the Long Pillars, if you die, there is a bell you can use, and as with boss phases, if you complete a stage of the trial, it's done and you'll start at the next.

I genuinely think Jing Ye is the most annoying boss I've encountered so far.…
