The minor health gain was intended to be unflavorful and just gave reasoning, in my head, to give it the stat boost when upgrading so that the cost wouldn't change when upgrading.
I personally feel this only slightly leans towards , but it already has Plate Armor and I do not wish for it to overlap for that. Aside from that, I could really choose any element otherwise.
I chose because outside of , which already has Quint, there are too many glass cannons in that would undoubtedly like the temporary protection and seems to me to fit my idea of it being cheap with short-term effects.
As for Spark/Salvager. I don't see any real issue with that.
Just thought I'ld throw some other options out there.
This could also fit under the
element well I think. It would make a nice parallel since it builds off the synergy between light and fire used by Seraph and has a very similar feel to the mechanic.
Another element that might work nicely is
... Maybe something like Vapor armor / Cloud armor.
Air, as an element, is given to evasion like tactics. This could also prove useful as a means of protecting your fragile creatures before detonating an unstable gas.
Further, air currently lacks a means of providing bonus stats.
It provides a similar, yet clearly distinct alternative from using SoFr to protect creatures from harm.
Then of course there is always
... since just about anything seems to fit there.
Personally I think it would be a very fun addition to air myself.
