How do you do spells on runscape? - Answers

You click on the spellbook icon, then click on a spell to cast it. Some spells may require to to cast on some object; for example in the case of a combat spell, you must select what you want to attack. For combat spells, it is better to choose the "autocast" option (right-click on the spell), to quickly cast the spell repeatedly. Most spells require items called runes, which you must buy, find or make. Moving the mouse over a spell will show you which runes you need. The runes are used each time the spell is cast, so you need a relatively large number of runes. You can save some runes by wielding a special staff; for example, one of the most basic combat runes requires air runes and mind runes. By wielding a staff of air, you save the air runes - but you will still need to buy the mind runes.
