Eh... I would have to think these will still be unnecessary as SMN magic skill (like that found on AFv3 +2) also provide a boost to the accuracy of Magical Blood Pacts
not all magic bp use tp hence wont benefit from the tp bonus on caller's1/2 and i am fairly positive the magic accuracy is superior to the accuracy gained from the +6 skill on caller's2 . i wouldnt full time these , but like most relic+2 , a nice macro piece for those occasions when its handy
The only lackluster piece of AF2+2, you shouldn't need the Magic Accuracy, the rest of the AF2+2 set already overkills Blood Pact delay. These are only useful for Spirit spellcasting.
Augment trial adds more Magic Accuracy for merit Blood Pacts.
