You mean a triad . A powerchord only contains root and 5th.

Yes. As davie explained, sticking to the same kind of 3rd takes you out of key (or mode). If you want to maintain phrygian mode, all of your harmonies need to come from that scale. As with any major scale mode, 4 of the notes are harmonised with minor 3rds, 3 with major 3rds.

So with E phrygian, it works like this

E -> G = minor 3rd
F -> A = major 3rd
G -> B = major 3rd
A -> C = minor 3rd
B -> D = minor 3rd
C -> E = major 3rd
D -> F = minor 3rd

If you used all minor 3rds, you'd effectively be harmonising E phrygian with G phrygian - you'd have a bi-tonal piece of music! (Might sound cool, but would be very strange...)
