I need to lower it by 3 so I can continue doing island training. I'm looking for a reliable, non-lab ray method.
Please help

Vortex negg has a chance to change your pets color, make your pet sick, raise its hp by 1, or decrease its hp by 1

thats the only chance u have

How sure are you on what vortex negg does?

The daily neopets says differently, but I know you're very experienced and I want the most certainty before I buy a lot of these.

Name: Vortex Negg

Reliability: Single Use

Average Rating: 3.00

Description: A magical negg, that can only be found at the Neopian Neggery. This negg is very powerful, but you can never tell what it will do to your pet, so be careful!

Other Effects:
May change your pet's color to the basic (red, yellow, blue, green) colors, increase/decrease max hp by 1, or give your pet neggitus.
