EK info request post update 45

[Reesi]

Can some EK obsessed player answer a couple questions I have?

1) Does spellsword damage land on the feats Cleave, Greater Cleave, etc? What about Destiny cleaves like Lay Waste?
2) Is it working with Strikethrough
3) does the T2 Sorcerer Savant Pierce <element> Resistance apply to spellsword damage.
4) Is Eldritch Strike and Eldritch Tempest benefiting from Strikethrough and/or Doublestrike?

Thanks

1) Yes
2) Yes
3) Can not confirm, as I play wiz-based, but I would assume yes
4) ST no, Doublestrike yes
