===Runic Dragons===

Dragons can do magic the "normal" way, but it's embarrassing and inconvenient to be a dragon caster that needs a spellbook.
*Dragons with exceptionally hard scales have a hard time carving spellrunes into their scales. Thus, wizardry is less common among their species. (Run like hell from a Diamond with spells.)
*It's difficult for a dragon to carve a spell into his own scales, so paying someone to do it (a common service in the scale trade) for you is the norm.
*Naturally, dragons shed their scales. Rune-carved scales are eventually shed, but they take 3 times longer. A dragon has to replace the lost rune when such a scale is shed before they can use that spell again.
*Runic dragons usually don't help other dragons become Runics. They don't share the knowledge of their runes, nor do they lightly offer to carve a rune for another dragon. The philosophy is "Earn it to learn it".
*Scales taken from a Runic while alive or shortly after death do not require mana to power, making them incredibly valuable for crafting shields and armor.
