Insightful Strike, from the Tome of Battle's Swordsage class, says:
At 4th level, you can add your Wisdom modifier as a bonus on damage rolls whenever you execute a strike from the chosen discipline.
At 12th level, you can choose a second discipline to which this ability applies.
Some maneuvers have you roll for ability score damage, like Mind Strike. (Others, like Drain Vitality do not!)
Additionally, checking the d20srd for damage, there is a section for ability score damage. This leads me to think rolling for ability score damage and weapon damage fall under "damage rolls."
Does this mean that the insightful strike feature can be used both on weapon damage AND ability score damage in maneuvers, so long as a die is rolled? Seems to me like yes, but was wondering if there was a specific definition for "damage rolls" which limit this to damage rolls for weapons.
