Hello! I see that you added to the Trivia that Blover, E.M Peach, and Hurrikale are unaffected by Mastery levels. Well, you are wrong. So please don't add false info to pages like that. Mastery Damage Pierce is also a percentage chance of a plant passing the effects of ineffectiveness or weakness in Buffs and Bruisez in Arena. Just pointing that out there. I hope you understand what I just said.
Okay, I guess that's fine... It's just that they do not have any damage at all. I have tested E.M.Peach and they can't even damage a Bug Bot Imp. The same applies to others, Blover and Hurrikale can not damage any non-airbone zombies. Hope you consider what I said. I will leave these articles like that. :)
Mastery Damage Pierce is for increasing damage (obviously) + increase the chance (by % as shown in the almanac) of bypassing ineffectiveness in Arena. The bypassing chances only apply to Arena (because of Buffs and Bruisez) while damage increase is for everything. Thank you for your reply! :)
