Determining Pet Dragon skill levels
 

Anyone know the function / command to figure out what promotions a pet dragon has taken?

Specifically, I'm looking into the digger skill.

If it's already selected as the attack, then (for example), tonum(Attack.get_custom_param("green") would tell how many treasure chests could be dug up. But I'm not sure how to figure it out if it isn't selected as an attack.
