In pathfinder, can an antipaladin deliver a held touch spell (e.g. inflict moderate wounds) and touch of corruption at the same time? I have quoted items that I feel are relevant.
From the Player's Guide: Holding the Charge: If you don't discharge the spell in the round when you cast the spell, you can hold the charge indefinitely. You can continue to make touch attacks round after round. If you touch anything or anyone while holding a charge, even unintentionally, the spell discharges. If you cast another spell, the touch spell dissipates. You can touch one friend as a standard action or up to six friends as a full round action. Alternatively, you can make a normal unarmed attack (or an attack with a natural weapon) while holding the charge. In this case, you aren't considered armed and you provoke attacks of opportunity as normal for attack. If your unarmed attack or natural weapon doesn't provoke attacks of opportunity, neither does this attack. If the attack hits, you deal normal damage for your unarmed attack or natural weapon and the spell discharges. If the attack misses, you are still holding the charge. (Emphasis mine)
Then
From the Advanced Player's Guide: Touch of Corruption (Su) – Beginning at 2nd level, an antipaladin surrounds his hand with a fiendish flame, causing terrible wounds to open on those he touches. … As a touch attack an antipaladin can cause 1d6 points of damage for every two antipaladin levels he possesses. Using this ability is a standard action that does not provoke attacks of opportunity.
My thought is that since touch of corruption is a supernatural ability, it doesn't count for the limit of one held spell at any given time. So before combat, an antipaladin would cast inflict moderate wounds and hold the spell. Then, he would attempt a touch of corruption. Assuming the attack hits, it causes the touch of corruption effects in addition to the discharged inflict wounds. Am I mistaken?
Best Answer
Yes, this will work, as a 2-stage attack.
Cast the Inflict spell (or whatever your touch spell would be) first, and hold the charge, as per your first quote.
On your next action, use Touch of Corruption as normal. When (if) you hit with Touch of Corruption, whatever you have touched immediately fulfills the trigger clause for "holding a charge", and the Inflict spell is delivered.
It won't work in the reverse order, as Touch of Corruption can't be "held".
