The bestiary and charms are here
Every creature you kill now counts in your bestiary, which you open from the Cyclopedia in the client. All 198 creatures of the 8.0 world have an entry, with the places they lived in 2007. Kill enough of one and you learn more about it, and when you finish it you earn charm points.
Charm points buy charms. Set a charm on a creature you've finished and it can deal extra damage to that creature, dodge its attacks or turn its hits back on it. Every character can use six charms at once, free and Premium alike. The few charms that need equipment the 8.0 world doesn't have aren't offered.
