Overflow Points

Overflow Points are the reward for completing Overflow Challenge

You can use overflow points to buy various perks:
 * Black Hole: increase the maximum number of black holes that can provide GP. Base cost: 15 OP
 * BHU: increase the number of universes that can provide GP on rebirthing. Base cost: 7 OP
 * Gem cap: gain the ability to create gems higher than grade 15. Base cost: 3500 OP
 * Gem gain: gain more gems from challenge dungeons. Base cost: 7 OP
 * V2 Autokill: QOL that allows you to autokill v2s for less might. Base cost: 3 OP
 * HP Regen: makes your HP regenerate faster. Basically useless. Base cost: 10 OP
 * Crystal Power: makes your CP more effective. Base cost: 7 OP
 * Light Clones: gives you more light clones. Basically useless. Non-increasing cost: 35 OP.
 * Creating Speed: increases your base creating speed. Base cost: 20 OP.
 * Powersurge: increases the effectiveness of powersurge, while also increasing levelling time. Don't bother until you can easily blackbar powersurge. Base cost: 4 OP.
 * Creation Count: unlocked at UCC30. Creates a multiplier for your base creation count. Base cost: 30 OP.
 * Might speed: unlocked at UCC40. Base cost: 30 OP.
 * Stats: unlocked at UCC50. Base cost: 10 OP.

The cost for the next level is (base cost)*(num bought + 1)

Because of the cost increase, it's generally hard to spend all your points in one area and better to mostly spread them around (aside from regen, which is useless). Buying more levels of BH is very helpful in 1CCC. Going heavier on CP, CS, and CC when available is generally a good plan.
