Question

I heard that it makes unevolved pokemon's defenses boosted by 50% but I also heard that middle pokemon like Grottle and Shelgon are only boosted by 30% is this correct.

Answer 1

Yes it does. If the pokemon hasn't evovled to its full stage it want get the boost. Never heard of a 30% boost

Comments

It's a 50% boost to both Defensive stats, regardless of stage; think of it as a free Cosmic Power boost.
