[Rendar]

Unlike Burn, which gets one last tick and then the status expires on round start, Vampiric Legume's HP drain on being Immobilized doesn't get this last tick. It cures Immobilize (round tick), and doesn't roll to see if you should do anything on that tick.

Which effectively makes Ingrain a 2 round effect.. Which is also considered a negative effect for you immobilizing yourself.

So you can accidentally cleanse it, or lower the duration on it.
