So the real advantage for choosing Dragonborn for a Fey Pact Warlock would be (i) CHA advantage and (ii) the tier 4 Evocation [EDIT + conjuration] DCs? Still good. Thanks for the reply!MCL has no effect on warlock blasts/pacts. The dice are based off warlock levels (or feats in the case AotS), 2 epic feats, and AP spent in certain heroic trees. The saves are evocation saves.
I don't have a feylock at the moment, but it's all basically the same thing with the save type changing around.
