Oh for sure, my current class obsession, the medium, requires reading up on the entire wizard, cleric, druid spell list in addition to your own, as well as prepping contingencies for weapon combat, temporary skill & occult unlocks, and figuring how to even use two more chasses that don’t touch any of those options, all before you start getting into the advanced cross-spirit synergies, like necromancy and body possession, let alone the customization options you mentioned.

Of course, then there are also your barbarians who really only need to know to hold their sword two-handed & be mad, so it’s not all chargen insanity.
