If you're just starting off, I'd say start with the basics b4 trying to cast spells. Not only are they the basics, but most likely the spells you'd try wouldn't work because of the lack of knowledge to back them up.
Say it again Shadow , the walls shall listen Ya' -_-
Spells should be used when there is need and intention for them. They are not toys , exercise devices or alikee. Furthermore , casting spells just to
- see If they will work
- try them out
- see how sucsesfull You are
- "practice" magick
- stun others and show them "magick is real" etc.
is a strong disrespect towards magickal practice and forces ( spirits ) we work with and will result in a fable and non-productive practice
IF You really CAN NOT holld back Yourself , try spiritual development spells , devotional spells and maybe wish spell. Some authors recomend Weather spells and protection spells but I would not completely agree ( just my humble oppinion )
Well Blessings and good luck in Your work , hope I was not harsh or anythin' :)
