Item World
Item World (IW) is one of the battle modes in the HentaiVerse mini-game. Item World allows you to do battle inside any piece of equipment not equipped to your current equipment set in order to level it up.
Rounds
An Item World has as many rounds as the equipment you enter has levels if it is under 100. The number of rounds if it is over 100 is:
round(log($level, 1.01)-363)
where 1.01 is the log base.
If you are defeated or flee in any round you must start over again to complete the IW for an item level up.
Item Potency
Clearing an Item World increases the potency of the equipment. The number of equipment levels gained depends on the Difficulty chosen.
EXP
The strength of the monsters and EXP gains depend on the quality of the item. A Magnificent item will have significantly harder mobs than a Crude one. Like in the Grindfest, monsters start at 50% base damage and increase by 1% per round. Experience gained is significantly higher than the equivalent difficulty Grindfest, however you do not gain any credits inside the Item World. Item World does, however, have the same drop quality bonuses as Grindfest.
Cooldown
After clearing an item, you cannot re-enter it for 20 hours (the counters starts from the equip clear time, not from IW start time), but you can immediately try again if you're defeated or flee. This time can be reduced via Spelunker training. Additionally, an Item World's cooldown time persists between players - if a player buys a piece of equipment that was recently cleared by the previous owner, they will not be able to enter it until the 20 hours have lapsed.
