With the use of a lectern, the players have the ability to craft magic tablets. Each level of lectern allows new spells to be crafted. To craft a spell tablet, players needs one soft clay for each tablet and the runes and Magic level required to cast the spell. Making tabs is very slow: 1 every 4.2 seconds, or 7 ticks.
There is a difference between the eagle and demon lecterns, and although they both gain more spells the higher level construction needed to build the lectern, Eagle tend to have only teleport spells (with the exception of the Lvl-1 Enchant spell), while demon lecterns are composed of enchantment spells, as well as bone alchemy (such as Bones to Bananas) with the exception of a Varrock Teleport.
