Compendium is your own, personal collection of information on monsters. As you kill more monsters, you unlock Ranks (up to 3) that give you a better understanding of the monsters you fight through bonuses. Reaching Rank 3 for a monster also gives a Multikill bonus!
Explore the Compendium by clicking it in the lower left-hand corner of your equipment window.
3 ranks for each monster, each breakpoint at 200k, 500k, and 1M kills.
The progress bar is colored according to the rank you're working toward. A full colored bar means you hit the rank.
Each monster has its own stat bonuses it gives at each breakpoint. Each breakpoint overrides the breakpoint before it.
For wasteland monsters, the stat bonuses for each breakpoint are about equal in increase. However, for abyss and maw monsters, the first breakpoint gives the most bonuses.
Reaching Rank 3 for any monster gives a global -1% multikill bonus, in addition to the stat bonus. For example, if you have 3 monsters at Rank 3, fighting the 4th monster would give a 27% stat bonus to the monster instead of a 30% bonus. Check the
Multikill page for more information and math about how much impact this bonus has.
Every 10 total rank points gives a +2% damage bonus.
All kills you have already made are automatically included in the Compendium.
To obtain each rank, the number of kills below must be met for each and they are a running total.
This means to get from Rank 2 from Rank 1, you would need another 300,000 kills, and not another 500,000 kills.
Rank 1 = 200,000 Kills
Rank 2 = 500,000 Kills
Rank 3 = 1,000,000 Kills
The rewards that you gain for reaching each rank can be seen in-game by clicking Character in the bottom menu, then clicking Compendium.
