One CC Challenge

Description
Your CC and currently held GP are reset, and your max clone count is set to 10 million (+2 million per challenge completed). You must reach your max clone count. This challenge is capped at 25.

This challenge is frequently called "1CCC" or even "OCC" by players, but the game's abbreviation is OCCC.

Unlock Condition
Have more than 10 Million max Clones.

Restrictions
The typical Multi Reset restrictions apply. In addition, your CC and GP are reset, and your max clone count is set to 10+(2*OCCC's finished) million. Buying additional CC is disallowed, as are Ultimate Shadow Summons.

You will not earn GP from gods if your previous rebirth was under 30 minutes. Pets cannot earn GP whatsoever. GP from God Crystals and Black Holes is doubled.

Reward
Challenge Points: 15 God Power Reward: 300+20*OCCC's finished Statistics Multi: 3 million

Increases your creation count for creating shadow clones by 1% per challenge finished, doubled (total 50%) after completing all 25 challenges.

Completions to Max
25

Recommended Stats
Decent pet growth (5M+) to climb gods, 200k%+ Building Speed from GP+CP, and a strong God Crystal RTI module (if going for a more idle strategy). Your max clones, CC, and any banked GP do not matter as they get reset for the challenge.

PBCs (+25 from UCC) and UBCs help with getting more GP from P. Baals.

Strategy
The basic goal here is to accumulate as much God Power as possible, and then spend it all on the 3GP 99,999 instant clone purchase. There are a couple different ways to get the GP you need.

The first way is to climb P.Baals as quickly as possible, rebirthing semi-frequently to get GP from killing gods repeatedly. Since rebirths must be longer than 30 minutes to get GP in the following rebirth, 30 minutes should be the minimum time you spend in a single rebirth. Continue to climb P.Baals (which is where the PBC reward comes in handy) until you have enough GP to buy all your clones using the 3GP instant clone purchase. (The amount of GP you get for completing the challenge should be the same amount you'd need to buy all the clones on a fresh rebirth.) Rebirths can be extended to 1.5 hour runs to unlock Might if you need a bit more power and/or can't be quite as active playing the game.

The second way is to start out with short rebirths (30min - might runs) at first and then do a longer rebirth after killing Baal to build Black Holes and a God Crystal. This is much more of an idle strat and will take longer to complete.

A small amount of GP can and should be spent on divinity or a couple instant clone purchases to build Black Holes (and upgrades) to propel you to higher gods. Just make sure the amount your spending can be made up for by the amount you would be getting from the higher gods climbed.

If you're feeling risky, you can attempt to fight UBv2s. Just make sure you Save before doing so, and Load that save file if things are bad and you lose too many clones. A good loop for the least amount of clones lost is "uursififirufififirutiwieivvc"
