How do you freeze players with magic on RuneScape?

Ancient magicks; the standard spellbook offers minor / lower-leveled spells with which to freeze targets for a short period of time, however these are not particularly as effective as Ancients. With Ancient Magicks, spells such as Ice Barrage (most powerful Ice spell) allow you to freeze an opponent and deal heavy damage.

There is a quest requirement for ancient magicks (Desert Treasure) and higher-tier spells do require a high magic level (level 94 for Ice Barrage) for more powerful damage, however the freezing/damaging effect of ice spells can still be dealt with Ice Rush, requiring a minimum of level 58 magic. As with all non-standard magic spellbooks, you must be a RuneScape member to switch spellbook and use Ancient Magicks.
