>Galewind
I like this actually. It's not some huge DPS gimmick like other sword cantrips and provides some nice battlefield control
>Ferrous
Don't quite like the minor adjustments to AC like this
>Venomous
Seems fairly strong since it's flat extra damage with no real condition or way to block it. It is poison though, so that might be fine.
>Siphon
Not sure how well this scales up, or if it's very useful at all. It is a lot of free temp HP in the long run, I suppose. Odd
>Frost
Need to fix the wording to cover the duration on it, but it seems strong. Extra AC plus even more punishing than Booming Blade in some instances. It does lock you into chaining it though, so better on Sorc or Warlock perhaps.
>Seeking
This one seems weird, especially because you probably want to use it on something invisible, but if it's invisible hitting it is a challenge
>Is the scaling on them too wonky?
The scaling seems fine in most cases.
>Are any too op?
Frost armor, Ferrous, and Venomous are the only ones that raise any eyebrows for me
>Any better ideas for names?
Seem fine overall, although Ferrous seems mis-named
>Any spells that should be other schools?
Maybe Gale-wind and Frost armor into Evocation, but that's minor overall
>Any other gish style cantrip ideas?
I was expecting Seeking Strike to be some sort of enhanced-accuracy attack at the expense of damage, personally. That might be an interesting direction to go for another sort of divination attack cantrip compared to this one, which seems more utility focused.
