Ninja Skill Update?

Yesterday, I noticed that Crippling Slash now costs 5 strikes of adreniline. I could have sworn it was only 4 last week.

Am I going crazy or what?

That change has been around for a while...

To the best of my knowledge, Crippling Slash cost 5 Adrenaline as of April 10th, but not before that time, as an unlisted part of the update. following the April 5th update granting it the bleeding condition.

Edit: Ah, here it is -

Nothing "ninja" about [skill]Crippling Slash[/skill] to the best of my knowledge.
(And whoever keeps those descripts updated is not doing their job)...
