Ultimate Baal Challenge

Ultimate Baal Challenge (UBC) requires the player to defeat Baal with almost all of their statistics reset, similar to having a new game.

Unlock Condition
Defeat Tyrant Overlord Baal.

Restrictions
The challenge resets your GP bonuses, unspent GP, CP, and your rebirth multipliers back to their starting values. One-time GP bonuses such as Improved Next At are not kept, but can be bought again during the challenge. The pets stat contribution is disabled, except pet campaigns, which can still be levelled. Might skills can be levelled but your permanent Might bonus is disabled. DRC might rewards are withheld, but CBC might rewards are not.

Clone dividers, training caps, and base divinity generator stats are kept.

During the challenge Lucky Draws cannot be opened, but they can still be collected.

After succeeding, you will get everything other than your multipliers back.

Recommended Stats
You will likely do one of these early on to unlock the crystal factory, but subsequent UBC’s benefit immensely from 1KC, AAC, and CBC, as well as the upgrade Improved Next At. Without some or all of these, UBC’s will likely slow you down more than they will help in the long run.

Rewards
The first UBC completed permanently unlocks UBv2 and the crystal factory.

100 GP + any GP not spend on pet food during the challenge (this does include GP spent on one-time clone and divinity boosts) + any leftover unspent GP earned during the challenge.

The stats increases of P. Baal 2 and on will be reduced by 1% per UBC completed, to a maximum of 50%. Since this stacks with each successive P.Baal, this reward can get VERY dramatic.

Each P.Baal grows in power by a factor of 100 - n, where n equals the number of times you completed a UBC, e.g. No UBC completed: 100- 0 = 100x power each P. Baal, 16 UBC's completed: 100 - 16 = 84x power each P.Baal. With no UBC's completed, the maximum P.Baal in the game will be v125. With all 50 UBC's completed this is extended to v147.

Focusing on clone making/killing in the first few rebirths can help a lot in later rebirths when you have more to focus on. Your initial GP should be spent on BS, with some beefy pets you can do some lucrative GP campaigns and try to get lucky with some of the GP dungeons for CC and CS as well. For newer players, focus GP on BS and rebirth as soon as you are green to maximize GP gains after Izanagi. Div Gen is mostly a waste of effort and you will be better off focusing on Mighty Statues and Mystic Gardens and using the time to stick pets in growth camps.

Having all of your 1 caps will greatly help speed up the time of this challenge, as well as having the premium upgrade Improved Next At For Challenges. A level 1 Planet allows you to more quickly kill your clones at the end of each rebirth to raise the clone cap.

Rewards from completed AAC, CBC, and 1KC challenges count for this challenge. Most other challenges also help but their rewards will not be as noticeable. For example, you do get the rewards from BHC, but it is highly unlikely that you will be able to make a black hole anyways. You also get the benefit of baseline DRC rewards, but they will not count towards your total might, similar to ghost might from CBC in the rest of the game.

(For Kong or phone app) Hoarding ad points can help shave off a lot of time on your UBCs, by spending them on creating speed to get you clone cap higher, earlier, or by purchasing divinity.

Rare items like godly liquids and chakra pills also help.
