Law staff

The Law staff is a magic weapon, released with the Dungeoneering update, on 12 April 2010. It costs 10,000 Dungeoneering tokens. Players can store up to 1000 law runes within it, and when used it has a 1/10 (10%)chance of not using a law rune. As a melee weapon, it is tied as strongest staff available in Free-to-play with the nature staff. The gravite staff has a stronger magical attack bonus. Strangely the inventory icon is upside down of how a player holds it.

Inconsistency in Requirements
The dungeoneering skill guide claims that players must have skill levels of 30 attack, 45 magic and 45 Dungeoneering to wield a law staff. However, in actuality, players will be unable to wield it until they have reached an attack level of 40. Thus, there is an inconsistency between the labelling on the skill guide and the actual requirements. However the instruction at reward trader is correct for attack level.

Cost analysis
The following is a comparison of the cost per cast of spells using Law runes while using an elemental staff as opposed to using a Law staff. The cost per cast when using the Law staff is approximate and assumes that exactly 1 out of 10 Law runes are saved.

Standard spells
Example on reading the table:
 * The cost of Varrock teleport using a Fire staff is 0 gold.
 * The cost of Varrock teleport using a Law staff is 0 gold.
