Did you know? Self Sacrifice and Tough

Did you know that when the Krielstone Bearer is disabled by an attack you get to roll tough before using Self Sacrifice?

Applicable rules:

Damage Application
"3. If the damage applied in step 2 fills the last damage box for a model, that model becomes disabled. Resolve effects triggered by the model becoming disabled." (Prime MKII Appendix A, Primal MKII Appendix A)

Tough
When this model is disabled, roll a d6. On a 5 or 6, this model heals 1 damage point, is no longer disabled, and is knocked down.

Self-Sacrifice
If this model is disabled by an enemy attack, you can choose a non-disabled model in this unit within 3" of this model to be destroyed. If another model is destroyed as a result of Self-Sacrifice, this model heals 1 damage point.
