Erm, but do you still want to retain your hero base damage?
When the hero is ordered to autocast the searing arrows, add it to a unit group. Likewise, remove the hero from said unit group when it unautocasts. This will allow you to track if the unit is auto casting or not.
Second, you will have to use a damage detection system to detect when the hero does damage. So, when it deals damage, check if it's in the autocast group. If so, set the hp of the triggering unit (attack target) to current hp + damage dealt. Then cause the hero to deal X damage to that unit.
but what if the hero does not use autocast and manually clicks

You might as well use Shadow Strike with no decay damage but only initial.
You could always use frost arrows. Use a damage detection system to check if any unit receives damage with the frost arrow de-buff. Then, block all damage received and deal 30 damage by trigger.
That's exactly what I told him. Read the thread, lol.
@ Arberden: You can't make non-autocastable spells autocastable.
