Ah, the thing is, we are talking about transcendentals.
The magic humans use involves borrowing the power of other beings, like Gods or Nastikas.
Transcendental abilities are when you use your own power to produce an ability.
Humans and quarters usually don't have any inner power to draw on.
We are more interested in transcendentals because if she's limited to normal magic, i.e. drawing from the Gods just like everyone else, it'd also mean that she'd be limited to existing spells (hoti and bhavati spells).
On the other hand, transcendentals seem to be much more diverse. The many different skills God Kubera showed are an example (ranging anywhere from great strength and speed to causing big holes to appear to opening gates between dimensions to summoning gold and mushrooms).
Even a Half like Kasak also had over half a dozen different abilities. Gandharva, before he was weakened, could freely change the terrain to anything he wanted.
Heres the thing though did he do all that? Kubera showed great str and speed, but it was implied that he created the dimensional gates due to his great str ripping holes in reality. Also the gold and mushrooms he easily could have dashed off picked some or grabbed some and come back so fast that you couldn't tell he left also explained through great str and speed. So we really haven't actually seen any non str based abilities from god Kubera, so we should wait and see before jumping to conclusions.
