Bror's Heavy Crossbow Grapple

[Secutor]

Using Bror's Bulky Heavy Crossbrow on Blannis Pike, I receive the folloiwing message when I try to grapple vertical or horizontal with the Unique Power Self Only.

This climbing tool cannot be used to climb up down, or across treacherous spaces. Target the top of bottom of a cliff instead.

When I attempt to use the targeting Unique Power as instructed, I get the message that it is unsafe.

Due to recent changes in 98, I'd really appreciate if this was checked in on. Thank you!
