Guild Wars 2

When hovering over several masteries, for example Bouncing Mushrooms, the tooltip shows “Requirements. Heart of Thorns: 10” at the bottom.
The mastery only costs 1 point however.
Does anyone know what the tooltip is referring to?

Is this for an account that does not own Heart of Thorns? Or…

I looked at an account that doesn’t own HoT, and the page was locked.
I looked at an account that does own HoT, and the tool-tips just give information about each Mastery tier.

Maybe a screenshot?

Here’s the screenshot

story step 10 maybe? the green star icon on the requirements suggest it is story related either way.

You’re required to have jump mushrooms and basic gliding masteries to complete some of the HoT personal story. I think this is just a warning to get you to train those masteries before you get to those story steps.

Looks like ‘Bouncing Mushrooms’ is required for Heart of Thorns: Story Step 10

Ah, that explains it. Thanks!
