Notes[]

1 Rainbow Gem will be received upon full clear of all difficulty levels.
Limited-Time Event.
All difficulties get a chance to drop Coby's, Helmeppo's, Mr.Prince's, Nico Robin's, Pearl's and Hachi's Manuals.
The higher the difficulty level, the higher the chance you'll have of getting one of the manuals.
The 30 Stamina is the best difficulty to farm for Coby and Helmeppo's. You still face both, but on different levels which means they can both drop.

How to Cobimeppo's Proving Ground[]

See Tips for New OPTC Players and Roadmap

General Information[]

One of the earlier FNs, and with one of the highest EXP return. Not particularly difficult once you have a mid-level team. It is usually recommended you bring a PSY team against an INT boss since they have no weaknesses against any color and are strong against INT characters. However, you'll face both a PSY and an INT boss for the final two stages. Bring a striker or fighter team comprised of PSY and INT units and you'll have all you need to beat this level. As usual, a slasher team works too but the options in the fighter and striker class are currently better.

Recommended Captains[]

There are quite a few choices, including:

Striker leads

Fighter leads

Slasher leads

Hawk Eyes Mihawk or Hawk Eyes Mihawk World's Strongest Swordsman: Generally brought for stats, you most likely won't need his special.
Donquixote Doflamingo Warlord of the Sea: Mostly for stats

PSY leads

INT leads

Legend leads

Most should work.

Recommended Support Units[]

PSY teams

Usopp Usopp Golden Pound or Usopp Impact are both excellent options for damage or for stalling. Make sure Rakuyo is your lead if you plan on using Usopp during a speed run.
Nico Robin and Mr. 3 Extra Special Candelabra for a burst round.

Striker teams

Nami Mirage Tempo or Nami Mirage Tempo: The Heavens to absorb one round of damage from Helmeppo.
Mad Monk Urouge, Maelstrom Spider Squard for stats mostly. If you plan on stalling a bunch their specials are both super useful.

Slasher teams

Sergeant Helmeppo
Ryuma, Shanks Black Clad Emperor, or Red-Haired Shanks: Mostly for stats.

Recommended Sockets[]

There really is no socket requirement. You might consider swapping out a few characters within 100 attack points for matching orbs, but nothing is necessary to beat this level.

Recommended Teams[]

Speed Striker Team
Captain	Subs	Friend	Ship

Requirements
This team has a lot of alternates you can bring. Substitute Usopp Impact for Nami if you have a low CD. Rakuyo, while weaker, tends to run this mission faster due to his cooldown reducer ability. He's best replaced by Kid.

Free to Play PSY team
Captain	Subs	Friend	Ship

Requirements
Most sub units can be replaced with other hard-hitting PSY units.

Power INT Team
Captain	Subs	Friend	Ship

Requirements
N/A

F2P Baccarat Sengoku team
Captain	Subs	Friend	Ship

Requirements
Lots of alt F2P subs. You don't need any specials, just smash.

30 Stamina Walkthrough[]

Most Mid to High-level teams should be able to clear this level without an issue. The trick is making sure you have both a INT and PSY unit team.

Grunts + Sergeant Helmeppo

Take out the grunts first before focusing on Helmeppo. Do not let Helmeppo attack after 5 turns as he will deal a massive 10,700 damage special. Use Usopp if you need to.

Enemy	Hp	Attack Pattern
Sergeant Helmeppo	370,000 hp	Will hit you with a preemptive attack for 3,300 damage. He then attacks for 720 damage per turn. After six turns, he will deal 10,700 damage!

7

Petty Officer Coby

Focus on bringing Coby to just above 20%. Then perform a burst round to take him out.

Enemy	Hp	Attack Pattern
Petty Officer Coby	600,000 hp	Will attack for 2,514 damage his first turn. Loop 1) He will stall and perform an attack boost on his second turn. Loop 2) On his third turn he will deal 7,500 damage. Under 20% health, he will deal 5,500 damage every turn.

Secret Stage

Training Helmeppo + Training Coby

Focus on bringing Coby down, then focus on Helmeppo. They both have incredibly weak defense so there's not too much to this stage. Coby will hit very hard and then go on a one turn Cooldown while Helmeppo takes away your ability to heal which is a really annoying combination. Take out at least one on your first turn.

They will both have the chance to drop their unevolved version.

Enemy	Hp	Attack Pattern
Training Helmeppo Training Coby	- -	Lowers your chances of healing. Attacks for 4,400 then has a 2 turn Cooldown.
