Term: Complexity, Complex

Complex Abilities are almost always spells and sometimes other features (such as some Hybrid Abilities or Unique/Class abilities). Complex spells do a lot, have better/more scaling than simple spells, and can do more for the casters that can wield them. Complex spells are more fanciful, even going as far as to mimic some class features with extra steps. That being said, Complex spells are almost always tools for the corresponding spellcasters, who lack in other ways.

As such, too, Complex Spellcasters can do whatever Simple spellcasters can, as well as ⤵/Augment Down their abilities to use less resources for similar spell effects.
