empower for 1200 gems. im f2p
Yes buy it, it will be worth, since you would have to spend much much more to get it from rolls.
I would say to use on heroes PD-> Athene-> Anubis->Michael in this order.
PD will help in dungeons and def modes with that talent,
Athene will provide energy buff constantly, but it would be better to use insignia on her,
Anubis will be good in dungeons also and GW defense, but at cost of good talent,
Michael for constant buffing, but like Anubis at cost of good talent.
Given the N of talents - 1 (Psyshield is not available as such) / N of levels available for each of them, you would definitely need more than 1200 gems to be really sure you get it and at level 5 as well, so yeah, go for it.
Yea, but give it to Anubis or PD. Nobody else can make use of it as a main talent. Athene needs SS or SL, Mike needs the same
