I passed along the ideas and they were well received (even the Latin, lol). As was me noting that while the pilum of fire had great penetration, it also could be stopped cold by the core spell ward against heat and flames - and at that point the would-be Hoplite would be well and truly stymied with no other options.
My player didn't especially like the idea of an investigator or running an agency, but the second draft took the dispelling idea into account. They are hoping both to have a shot at dispelling any wards against their cold spells in the short term, and be able to quickly develop a similar dispel for every other form in their first few years to be a reliable dispeller. (Meanwhile, 5 castings of Winter's Icy Touch is enough to fatigue a lot of enemies into unconsciousness.)
(Apparently those single points spread across forms were to get the associated resistance bonuses, but I pointed out those weren't likely to help much.)
They're considering swapping in either Wizard's Communion or Pit of the Gaping Earth, or seeing if they can add something for dealing with groups of enemies. I don't want to suggest anything myself since I'll be throwing them straight into an adventure in season 1, at their own request. (Quote: "Challenge accepted, ST"). But the player is interested to hear opinions from the peanut gallery.
