Magic tablets are magic spells that are sealed into clay, which allows the spell to be used later. Clicking on the magic tablet in the inventory activates the spell.
Magic tablets are generally created by using soft clay and runes on a lectern in a player-owned house. The tradeable tablets provide players with a method to gain the benefit of a spell before reaching the required Magic level to cast it. However, for base spells which require quests, the tablets also require the same quests. For example, Plague City is required to use the Ardougne teleport tablet.
Tablets are useful in situations where inventory space is critical and/or where inventory-based activation is useful. Players on a different spellbook (Lunar magic or Ancient Magicks) may find it useful to have access to a subset of spells from the Standard spellbook.
These tablets mostly contain spells from the Standard Spellbook. Exceptions include the Heart tablets, which require Tales of the God Wars to use, and the Dagannoth Kings tablet, which are exclusively dropped by the kings and cannot be crafted.
Players can unlock the ability to create tablets that teleport to different locations around Menaphos (and the Sophanem Slayer Dungeon). The district teleports require rank 4 reputation in their respective district whereas the Sophanem Slayer Dungeon and Shifting Tombs teleports require rank 4 reputation in any district. They are all made with one soft clay and two law runes at a lectern.
