Firstly, the Dreamspun sorcerer's bloodline arcana says that you gain the relevant insight bonus "whenever you target a single creature with a spell". How does this work with spells that allow you to target a single target each round? When you make an attack with calcific touch, does it count as you "targeting" a "single creature" with the spell each time?
Also, a Dazing spell has a chance to daze an opponent "when (the) creature takes damage from this spell". Does the dex damage from calcific touch count? (A little cheesy, I know. XD)
