Sorry if this is in the wrong board.

But I was wondering, all all the tools that are usually listed (ex.- wand, altar) really necessary? Or are they just good to help channel energy?
I understand using a candle, and other certain objects for symbolization in spell, but I'm just curious about some of the other tools that are common for spells and such. Especially since many people may not have direct access to a means of purchasing them without turning to the internet.
