This is an old stuff I used one year ago and I'm wondering if it is a good idea to upgrade it to stellar or not ? There is no critical because it didn't exist before... So I research critical mainly on gems currently because I don't want to find new stats on shadow (now it's impossible to upgrade a non shadow to shadow and then radiant I believe ?).
