|Release||4 September 2017 (Update)|
|Destroy||If destroyed you can find another on the floor in Death's office.|
|On death||Always kept outside Wild|
|Examine||A book containing a log of drops obtained from bosses.|
Certain listed items dropped by non-boss monsters and other bosses count towards boss collections, such as:
- Ancient Warriors' equipment and Corrupt dragon equipment (from Revenants)
- Dormant Anima Core equipment (from the original four Heart of Gielinor generals)
- Draconic visage (from all monsters which drop it)
- Godsword shards (from the original four God Wars Dungeon generals and their bodyguards)
- Warpriest armour (from the original four God Wars Dungeon generals, their bodyguards and followers)
- Dragon 2h sword (from the Giant mole, Kalphite Queen and Chaos Elemental)
CoinShare drops are not counted towards your collection, since the item is split into shards and is not a full item. In addition to this, any untradeable items obtained prior to the log's release date (such as pets, defenders, etc.) are already included in the log.
The following titles can be unlocked through obtaining drops for the boss collection logs.
