Fixed the phrase spoken when using the Cult Armor rune, also updated a few comments

Up until now using the "Cult Armor" rune would spout the same phrase as
"Summon Tome". The correct phrase is written on the talisman that
cultists get at roundstart.

A minor fix really, but muh immersion, muh lore, etc
