Ultimate Baal Challenge

Description
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.

Strategy
You should generally wait to do your second UBC until you have your one-caps. Several challenges, such as 1KC, GSC, and CBC, help with UBCs; it's generally best to have at least 5 CBCs completed to help with unleash times. You should also have unlocked FSM and Nightmare to uncap and double GP gains.

Your main goal during the early stages of a UBC is to get more clones. In early rebirths, this will involve killing all of your clones as fast and as often as you can. You should be running GP camps and GP-producing dungeons (SY D1, WT D1, Volcano D2, and if possible Mountain D3 with rebirth bacon). GP can be spent on clones up to 150-170k and on BS. GP should not be spent on CS or on CC - you can use the 3GP clone buy to max your clones each rebirth instead. 2-hour rebirths are typically fastest, although feed runs are also fine.
