I think most of you have heard someone say "where theres a pro theres also a con" or "wait whats the catch?". Is that always true, meaning magic would work the same way and every good spell will also have a downside?
Not all spells backfire, it depends on many things:
Yes - if you are doing it wrong: ill intent, wrong spell, not focused or angry while casting, not specific enough and so on.
No - if you are prepared, calm and focused, right spell and good intent and so on.
Do your research and here is some info:
No, not really. As Lessa said, there will be backfiring of spells if not done correctly but all correct spells won't have a "downside"- unless you consider that you'll be using up your energy, the amount varied based on how powerful a spell you're doing.
