Only three spells-Mudslide, Earthen Missiles, and Earthquake-are Physical, for Archmage.
"But, that's reasonable. The others are utility.", I think.
Then I realize that's silly and that two of them could easily deal damage as well as be utility.
Here's my thoughts:
A: Change Dig to Pulverizing Auger(or some similar name), a blast of rocky force or large, earthen, drilling column, etc., thematically.
Then, rather than make it dig (talent level) squares in the target wall's direction, within range 10, you make it a range (modified talent level+2) range ray that both digs down walls within its line, and deals (40, 280) Spellpower(stronger than most rays) damage to anything caught in it, with 8-10 CD and 30~ Mana cost.
Now, it digs...but it also does tons of lowish range physical damage in a ray form. Doesn't quite dig as well, of course, but the flexibility is what makes it more interesting.
B: Stone Wall doesn't form if an enemy is caught in its radius...but it also doesn't damage the enemy.
Why? You don't want enemies caught in the radius, sure, and an enemy blocking the way of formation makes sense... but forming a stone wall on top of them should hurt, shouldn't it?
Here's the thought here: If an enemy is caught in the walls, so that no wall forms there, deal (25, 300) Spellpower Physical damage to them instead of just no damage. For the targetted version, also let it deal that much damage to the target, because why not?
This should be easy to accomplish by having a no self damage 1 radius ball around the target for that damage.
Now that'd give Archmages five physical spells, and not just three. It'd help out that build a lot, and maybe more people would take higher Earth spells.
