Is it so that if you get coordinates to dig at you will always get a sara mage when not in wildy?

No, some times you will get a zammy, but most times you will get a sara mage.

I heard my friend said that it's real that you get mostly sara mage.

Need some straightened up

 

Your title should describe what the topic of your post is. Something like Do you only get Sara mages in non-Wild? would describe your post more clearly and get more responses.

 

 

 

To answer your question, since the Treasure Trail update this spring you may get a Zammy mage instead of a Sara mage in the non-wildy coordinate clues. Zammy is a lot easier to kill than Sara.
