† The Respawn Timer of a Boss or World Boss may vary by as much as plus or minus 33% to discourage Spawn Camping.
To find this mob in-game, use BACKSPACE to open the World Search window, then enter Cayus in the Search field and click "Search". Remember, the field is case-sensitive and must be entered exactly as shown.
A Word About Common Drops: Every mob in the game has a chance to drop Sigils, Health Potions, Mana Potions, Ammunition, Runes and Festival Items, as well as a few rarer items such as 
Amulet of Light. For this reason, we discourage listing them in the Known Drops section. See Common Drop Table for more information. Exception: All mobs always drop the same Production Rune and we will list it.
This mob does not have a Monster Compendium card.
