You can open the monster log from the warehouse. Monsters encountered in the adventure are listed after the adventure is over.

If you encounter a monster, the monster is listed even if the adventure is aborted.

The monsters are sorted by level and EXP.

The number on left [#123] is a serial number of the monster. If monsters are added in future updates, the number will be changed.

The number on right is a times which you encountered and won the monster.

The level is the monster's level. You could not know the level on one encounter. If you won sometimes, the level will be known. EXP is gained EXP points if you won the monster.

Other items are same as adventure logs.
