This trigger is the same as Pre-Roll Test, except it only runs for weapon Tests. Additionally, if an effect is owned by a weapon and designated as an Item
Document Type effect, scripts with this trigger will only run when that specific weapon is rolled.
If you want to add modifiers to the Test target or SL, you should use the Dialog trigger.
