I am looking for the cumulative defensive value when applying the following feats & effects. This example assumes I have the following feats and am opting to spend an extra power point when casting an at-will.
Predictive Defense (PHB3) Benefit: Whenever you hit an enemy with a psionic at-will attack power that is unaugmented, you gain a +2 bonus to all defences against melee attacks until the end of your next turn.
Prescient Dodge[Augment] (Psionic Power) Benefit: Whenever you hit an enemy with an unaugmented attack power, you can spend 1 power point to gain a +2 power bonus to all defences until the start of your next turn.
Mark of Warding[Dragonmark] (Eberron Player's Guide) Benefit: Whenever one of your powers grants a bonus to a defence, increase that bonus by 1.
What are my defences versus melee & range? Things I'm considering in this is will using prescient dodge void predictive defence or would they both apply as prescient dodge requires an unaugmented attack power to use and you spend the point after you hit? Lastly, will Mark of Warding up the defence of both prescient dodge & predictive defence should they stack?
