The Superhero Database Classification number, or SHDB Class, is a number that represents the overall 'power' of a character. All traits of a character are used for calculating the Classification.
What it DOESN'T mean
This doesn't mean that a higher class would always beat a lower class character. But the bigger the difference in Class is, the more obvious it is who'll win in a fight.
How is this calculated
( INT^1.3 + (STR*0.5 )^2 + (SPE*0.5)^2 + DUR^1.6 + (POW + (SPS*SPL))^2 + COM^1.8 ) ^ TIER
Super Power Score and Level
Every Super Power has a score (SPS) that is used to calculate the Class. Each Super Power also has 3 levels (SPL). The level is set when connecting that Super Power to a character. The level determines the final score, of the Super Power, being used in the calculation.
The power of Zatanna also includes elemental magic, where he can control fire, air, ice, water, soil and temperature. With this ability, Zatanna can control the weather, create a force field, fly and so on.
Some of the strongest magic Zatanna has ever used is traveling between dimensions, changing body size, manipulating possibilities and many others. Besides that, Zatanna can also read minds, erase memories, see arwag, telekinesis and super physical endurance.
The limits of Zatanna's magic power are still unknown, even almost unlimited.
