This is where the mods want us to be mature adolescences/adults. They want us to gauge for ourselves, in a fair manner, how much strain each spell would put on us. They do this because they still want to allow others to express their creativity in what they DO with certain spells. That being said, creating a dragon out of metal that flies around Regalia, shooting fireballs out of it's mouth would exhaust the user before construction was complete. But, holding say a clump of dirt, and allowing it to ignite, would be possible, and probably wouldn't take much away from the caster. Shields, they've gone into great detail about. Weapon enhancing through use of elemental augmentation is also something that would go on a case by case basis. Using the sword as a channel to cast a spell (such as "the blade begins to glow blue as the wind picks up around ____") would take significantly less energy than maintaining a spell that changes the blade itself (such as "the blade instantly alights with an unnatural flame") That being said, no 21 year old will have an infinite amount of energy to expend, nor will even the oldest living being in Aloria. However, that being said, a 180 year old person who has practiced magic his entire life would have a much greater affinity for spellcasting than said 21 year old. As for racial spells, the only one that I think would exist is Yanar's unique form of healing in which they use a rose as a channel to be able to heal wounds. Hopefully this has been a bit more helpful, and made things a bit more clear, and if you still have any questions, as either the mods, or perhaps another player that you think knows what they're doing with magic, not the ones that try to summon giant metal dragons as stated previously.
