>>95964664I dont know about Genesys but I can explain how Ars Magica works. In Ars Magica, using Hermetic magic involves combining one of five Techniques with one of the seven Forms.
>Techniques: Creo (I Create), Intellego (I Perceive), Muto (I Transform), Perdo (I Destroy), Rego (I Control)>Forms: Animal, Aquam (Water), Auram (Air), Corpus (Body), Herbam (Plant), Ignem (Fire), Imaginem (Image), Mentem (Mind), Terram (Earth), Vim (Power)So if you wanted to make a fireball spell, that would be Creo and Ignem (I Create Fire). If you wanted to make a spell that lets you fly, that would be Rego Corpus (I Control Body). Your mage has a level for every technique and form, and you combine the two to get a base casting total before adding various bonuses. Every combination of Technique and Art has a set of guidelines to sort of give you an idea of the base level of a spell. Then you add to the level of the spell depending on what you want its range, duration, and target to be, with every factor that you increase one of them by adding 5 to level of the spell.
So lets say I want to make a spell that teleports a target 50 paces into the air, letting them fall to their death. Looking at the guidelines that's a base level of 15. I want the range to be Voice, as far as my voice can reach, which is one level above Touch, which is a level above Personal, so Voice is two factors above base, so I add +10 to the spell level. Duration should be momentary, which is the base so I don't add anything for that. Target is individual, which is also base, so nothing for that either. So in total, the level of the spell is 25. So my Rego and Corpus score, plus my bonuses, plus my d10 dice roll has to be 25 to cast the spell!
When you make magic items, you basically get to add "spells" to them, and can decide what conditions trigger them to make basically any kind of effect you want. It's awesome.
