A curse spell is any spell that causes a negative effect to its target other than damage, such as lowering stats. Curses are an rarely used part of Magic, mainly because spellcasters have little time to waste on casting non-combat spells. In long fights, using a curse spell or two at the beginning may be a very good idea. Curse spells can only be used once for a short period of time for most opponents; unless the curse 'splashes' and does not affect the opponent, or you are 'battling' a dummy. There are dummies located throughout RuneScape, but the best place to train on dummies is in Lumbridge. You can also get free air and mind (30) runes from the Magic Tutor in Lumbridge. Please note that you can only get the runes every 30 minutes and that the Magic Tutor will not give you air or mind runes if you have any in your inventory or bank
