for what exactly? are you studying dragon magic, or any old spell will do? either way, you want a protection, healing, luck, love, curse, so on so forth.
there is no 'basic dragon magic' you learn basics then move to dragon magic. candle magic is rather straight foreward, you just have to remember the colours. as it goes on mind, you need to know moon phases, days best to cast and dieties along with anointing oils, but for a quick and easy starter, candle magic is one of the best. work on meditation charging/grounding energy. these are the most important thing for a spells success.
