Thanks for the post, Catapult, and sorry for the belated reply.
A week of translating tutorial text has by brain reduced to a mass of goo with a consistency somewhere in-between Oliver Twistian gruel and driveway slush.

This Decreased HP status help text is definitely not doing what it's supposed to be doing--help. Most of the statuses are being revamped for ARR, so I'll make sure to fix this one when the time comes. As for your comment on poison... I had the same discussion recently with the battle team devs... /sigh... I'll keep trying, though
