To help players understand exactly what spells will be available, I would suggest this addition to the hiergammemon.
The idea is that you can filter the list of spells after certain spell traits. For example, I might select lvl 3 fire and lvl 2 air. This will show me ONLY those spells that become available as a result
Fire only:
Burning Hands
Pillar of Flame
Flame Dart
Feedback
Fireball
Focus
Air only:
Haste
Evade
Aura of Grace
Guardian Wind
Fire2+Air2:
Tireless March
In addition, this entry should be available from the trait selection screen.
