Swigger's Spellbook

Swigger's Spellbook is a tactical spellbook that one can use in the game Runescape (oldschool). It has the best spells in the game (unfortunately it lacks spells such as Crumble Undead, Low Level Alchemy, and Wind Surge {making it completely useless [Unless you have talked to Donie 4880 times in Lumbridge] } ).
