Theta is the eighth World available to Hunting, and it is only available after the 2nd Ascension. It is composed of 10 Zones in 4 different backgrounds.
The kill timer for each creature in Theta is always 10s for the 'common'. Bosses will always be 40s.
If the player hasn't achieved Inferno Mode the number of kills required to move to the next stage will always be 90 in Theta, although bosses will require 10 for the 1st boss, then 15 for the final boss.
