Level Restrictions on Spells?

[TaylorBland]

Not counting the Spell Level itself, i am working on a sort of Avatar the Last Airbender campaign (in a slightly modified universe), Where each of the 4 nations can have Benders. the Bender Variant of the Human Race has Spells linked directly to it. At level 1 they gain a Cantrip and one Level 1 Spell based on their Element (earth, air, fire or water). at certain levels they automatically gain new elemental Spells.

How would i go about scripting the spells that are limited to level?

In this world, there are not Spell-casting Classes and only use the following (Barbarian, Fighter, Monk, Ranger, and Rogue). this is to show that only the Bender sub-races can cast "Magic". it is because of this, that Benders just gain a new Spell at a later Level.

I'm still working on the sub-bending types, like Lightning and Blood for example. i may not even do those. but anyway...


Or would i have to create some kind of extra thing like the Divine Domains (that grant certain spells at certain levels anyway)?
