The chameleon's Arcane Focus option states the following:
Arcane Focus: You gain the ability to prepare and cast arcane spells, which may be chosen from the spell list of any arcane spellcasting class. You prepare and cast these spells just as a wizard does, including the use of a spellbook
Emphasis mine. Here is a rule for wizards and the use of a spellbook:
A wizard must study her spellbook each day to prepare her spells. She cannot prepare any spell not recorded in her spellbook, except for read magic, which all wizards can prepare from memory.
My question is whether a chameleon is able to prepare Read Magic from memory the way a wizard does. Essentially, does a chameleon with Arcane Focus follow all rules about wizards preparing spells (except when chameleon specifies otherwise) due to the use of "just as," or is the second quote somehow separate from that, applying only to actual members of the wizard class?
