A Title Much Cooler Than Anything on the Old Site
yeah, while I read it as components and casting time requirements being waived when cast with wish, even if interpreted as you do, I wouldn't impose the risk of never being able to cast wish again. But increasing the area of effect and damage of the spell should IMHO.I my opinion the requirements are things like needing to be a cleric or druid to cast certain spells and needing to have a spell slot open to cast the spell. Once you pick the spell, the parameters of the spell are set. If you are mimicking fireball, it takes effect in 1 action, has a range of 150 feet, a duration of instantaneous and fills a 20 foot radius area. Components are a bit of a conundrum for me. I'm not sure if they would be requirements or not. I'm leaning yes.
If you take away range, duration, etc., it's no longer a fireball. It's some other fire explody spell. I would rule duration is not a requirement. That said, using wish to make it faster is such a minor difference that I would not make the player roll to see if the wizard loses the ability to cast wish.
