Tome of frost

The Tome of frost is a reward obtained through the Dungeoneering skill. It requires level 48 Magic and level 48 Dungeoneering to use. However, by the current standard 430,000 experience is needed to gain the item, effectively pushing the actual requirement to 64 Dungeoneering.

The tome of frost acts as an infinite stock of water runes when carried in the offhand slot. It works the same as a staff of water, except it is held in the offhand slot. This can be useful when using fighting with a weapon and also casting magic, as you can have access to a staff and the tome providing unlimited runes of multiple types. It also greatly reduces the amount of runes needed to attack with magic; for example, when wielding a staff of air with the tome of frost, the cost of a Water Wave spell would be reduced to a single blood rune. It also works with Lunar Spells like Humidify. If wielded along with a lava battlestaff, the wielder would have an infinite supply of every elemental rune besides air.

The tome is also extremely useful when training magic with ice burst, as the user can have the benefit of water staff in offhand, allowing them to use a damage-boosting staff such as the Staff of Light.

The tome of frost will never degrade, which makes it the ideal for mages, it also provides the highest F2P magic bonus for the offhand.

(Spells ineffective for training, and also spells using single kind of elemental runes are omitted)
