Leader's Talent

Leader's Talent's level 3 ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered or otherwise leaves the stack.

You can't activate an ability that advances a Class to a particular level if that Class is already that level or higher. For example, if a Class is already level 2, you can't activate the ability that advances it to level 2 again.

Each Class starts at level 1 and has the abilities in the top section of its text box. Once a Class advances to level 2 or level 3, it has all of the abilities listed in the associated section of its text box as well.

Class cards have multiple text box sections. Other than the top section, each section contains a class level bar that includes a cost and a level number. Each represents an activated ability with the listed cost that advances the Class to the level listed in that bar.

Gaining a level won't remove abilities that a Class had at a previous level.

An ability that advances a Class to a higher level is a normal activated ability. It uses the stack and can be responded to.
