Spells without spellcasting methods that are slotted into a cast activty behave funkily- not being able to have their spell level increased and displaying no level (just the spell school) in the chat message. This leads to the spell always being cast at its base level.

From Dewi on the discord (repro steps)

can you recreate this:

• create spell in world
• give it a damage activity with scaling
• make sure the spellcasting method is empty
• grant that spell via a cast activity to an actor
• increase casting level
• use spell

Spell ends up not having a "level" and is treated as its minimum level no matter what.
