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