- "A darkness radiates from the monument, causing many things to become difficult to see. You catch a brief glimpse of movement nearby... Was that Abaddon? Upgrading this ancient will allow you to sneak past monsters when exploring."
Kumawakamaru reduces monsters required to kill per non-boss zone. The integer part of its effect shows the reduced monster per normal zone, while the decimal part is the chance to get one monster fewer.
For example, the effect of -2.33 means number of monsters per normal zone is 8 at most, with a 33% chance to have only 7 monsters per zone.
Kumawakamaru's summon cost is the player's current summon cost.
Kumawakamaru's cost per level is 2n, with n being equal to the next level.
All costs except the summon cost can be reduced by Chor'gorloth.
The monster reduction follows the equation:
-number of monster reduction = 8×(1-e-0.0025n)×Effect of Borb
- Kumawakamaru is likely a reference to Hino Kumawaka, née Kumawaka-maru, who was most known for avenging his father by killing a lay monk while the monk was sleeping.
- Kumawakamaru effectively maxes out at level 14972, as does Fortuna.
