what’s more cool is stout heart. it means earth ponies have super chutzpah powers. they’re harder to discourage or falter, which is a head canon I’ve been hoping for since pinkie in cutie mark chronicles. pegasi and unicorns may be OP, but you almost never see an unhappy earth pony.
 
was hoping it’d be serendipity powers, but stout heart is ok

It would also be an elegant way to have “spells” for all ponies.
 
3rd level earth pony talent: Green Hoof (D6)  
You can cause plant seeds to experience a growth spurt when you hold them. Once per session, you can add a d6 to a Body test you make for that purpose.
 
3rd level pegasus pony talent: Lightning Buck (D6)  
You can cause rain clouds to release a bolt of lightning when you kick them. Once per session, you can add a d6 to a Body test you make for that purpose.
 
3rd level unicorn pony talent: Eldritch Blast (D6)  
Your horn can produce a beam of destructive force. Once per session, you can add a d6 to a Mind test you make for that purpose.
 
I made it all up. But I sure am excited for the actual talent list.

I now suspect that Flight and Telekinesis might be talents rather than main abilities like Body, Mind and Charm.
 
It says on the page that earth ponies start with a “free additional talent: Stout Heart (D6)”. That’s how they increase their Body die and can add a d6 to a Body test once per session.
 
I could see other pages having things like “free additional talent: Flight (D6), you can fly and once per session you can add a d6 to a Body test involving flight” or “free additional talent: Telekinesis (D6), you can move things magically and once per session you can add a d6 to a Mind test involving telekinesis”.

It did, on one occasion, but fans inevitably use it to justify all kinds of stupid stuff.

Nice to see that “Earth ponies are stronger/tougher than pegasi or unicorns” is being made explicitly canon here. We’ve all pretty much guessed that, but the show never comes right out and states it.

Applejack now game-canonically stronger but dumber than Pinkie Pie.
