Hello! I’m a relatively young trainer, and I recently mega evolved my venusaur for the first time. However, I’m worried I might do something wrong when I inevitably find a gyaradosite. Is there any advice I can have? (I’m a Kantonian trainer if it helps)
To preface: I discourage all use of megaevo. My opinions will be extraordinarily biased.
Firstly, megaevo has been off the market for years now, unless you're working with a specialist it should not be an 'inevitability' that you find megaevo stones. They're off the market and legal tournament banned.
If you do happen upon a gyaradosite somehow, I would HIGHLY advise taking it to the nearest research center to drop off. Gyarados exposed to gyaradosite suffer short term, and in extended use cases, long term brain alterations and damage.
If you'd like further information I would go to your nearest specialist and do NOT use it without assistance from said specialist.
