Had a question come up.
1. The round after you cast chill touch can you use your pool strike and stack it with the chill touch charges you have left? Aslo, if you use spellstike to deliver the pool strike does the chill touch count?
Seeing as pool strike is a standard action with a free touch attack, it doesn't seem to count as casting a spell to dicharge the remainning chill touch.
2. The same question about pool strike remains for elemental touch without the spell strike (unelss i'm wrong about spell strike not channeling elemental touch)?

RAW, using a Supernatural ability is not casting a spell, so it would not cause a held charge to dissipate.
As for delivering both, I don't see anything that specifically says you can't, but I suspect the intent is that you cannot.

Elemental Touch is not a touch spell, so it does not work with Spellstrike.
RAW, you would deal both Elemental Touch effect and a held Touch spell if you used an unarmed strike, a claw, or a slam, due to the wording of Elemental Touch. I suspect the same would be true for a touch attack. (RAI very probably not.)
