"En-" abilities.

A question mostly for JP players as I don't think we have these abilities yet.
With Lightning's armor coming in the next event's second banner, my question is: Soul Breaks like Stormborn change the element of every attack, including the element of SBs/SSBs? If I use Stormborn, then Lightning's non-elemental SB, will the latter be lightning elemental?
I also heard somewhere of a 5* spellblade skill that attacks 2 times + En-Aeros the character(may be wrong though). Would the gained status influence that of an eventual SB?
