From PvP Superior Runes of Lyssa:
- (6) When you use an elite skill, lose all conditions and gain all boons for 5 seconds.
When using Tome of Courage or Tome of Wrath no conditions are removed and no boons are gained.
When using Renewed Focus because of how the spell works no conditions are removed (nor boons gained) until the spell is done channeling.
I think that this is unintended behavior and the effect from the runes should proc on cast with this particular skill because of how it works.
