Originally posted by XkeeperThis is kind of a challenge, since no matter what method you choose you'll need to grind on a single map a bunch until your total extracts reach 9 999 999... You want it to be efficient and mindless, so I'll avoid setups that require spell buffs or Magichange; also I know you're avoiding unique characters and the Sage class so I'll avoid anything from those too. A large part of the grind is actually preparing for it, haha.
Can you write up the fastest way to grind shards/extracts that won't bore me senseless?
20* carnage Asagi stage is probably way more efficient (doing the math, it'd take up to 27 runs with Metallia), but without a Sage's Land Decimator or Metallia's Greedy Mekhashefa, second-best is probably carnage Martial Training 4: at 20* it would take just over 200 runs, but each run should take way less set-up. The main problem is that the bears have about 1.1 billion HP, and (let's be conservative) 40 million DEF, and if you don't want to whittle them down then you essentially need to one-shot all nine with the 3x3 capture skill...
You can use a curry with 100 Thimbles as extra ingredients in order to get 100% guaranteed crits (which by default deal +50% total damage), then use a 100 Professional innocent to get another +100% damage so that crits deal 2.5x total. Then you can use Dark Knight's 4-slot evility Purgatory, which makes attacks deal 1.5x damage if they're crits. Thus you're guaranteed to deal 3.75x base damage with one innocent and only four evility slots!
At this point you still need to effectively deal about 295 million damage in one hit; bears have -25% resistance to fire, and -30% resistance to sword, so if you equip a sword in your main hand and a weapon with unique innocent Burner (to turn neutral attacks into fire attacks) in offhand then you take advantage of both weaknesses and only need to deal about 182 million damage.
Simplified to ignore all of the above, the damage formula is:
Damage = [SkillPower% * ATK * (100% + ATKbuffs%) - (DEF/2)] * (100% + DamageBuffs%)
From my very limited tests, the Capture 3 skill has about 175% skill power (where a regular attack is 100%); you want to maximize +stats% evilities and +ATK% evilities in order to overcome the bears' 40 million DEF, but then also stack +damage% evilities afterwards.
Assuming you have 10 million basic stats, then your first priority should be reaching +100% stats so that you have 20 million ATK. Taste of Victory is a 1-slot evility earned from Demon-level Chara World (or above) that gives +1% stats per map clear of the current map, so eventually it's gonna reach +100% which is basically perfect for this. Otherwise you could run 1-slot Cyan Power (+20%) and 1-slot Unstable Power (+50%) for a while.
You probably only have two free unique evility slots (from the 10000 mana bill, and the carnage Prinny overlord), but you're able to get the full two rows of common evilities so I'll assume you have all of that available. I think the following list of +ATK% and +damage% evilities is probably optimal:
- Assault Attack is notable here, since you want to attack the 3x3 group from their backside anyways (for side-/back-attack bonus damage), so if the unit isn't flying then they'll move 12 panels to go around them all (equip some carnage shoes), for +120% damage. It's a good thing that a Valkyrie is your main unit!
- Elemental Force reflects your current elemental resistance as an ATK% buff when you use that element; since you're using a fire attack (thanks to Burner), you'd want a 100 Firefighter in order to reach 99 fire resistance, for an easy +99% ATK;
- Magic Bundle is +30% ATK but skills cost 50% more SP.
- Over Limit (5 slots) gives +50% ATK but you lose 10% SP every end of turn; not an issue if you successfully capture all nine bears on turn 1;
- Mana Scarcity (4 slots), an Overlord-difficulty Chara World evility, gives +50% ATK but you only gain 30% mana;
- Attack Weakness (4 slots) gives +50% damage when hitting an enemy's elemental weakness.
With all of this, overall you have +229% ATK and +170% damage, so with 20 million attack, Capture 3's 175% skill power, and the bears' 40 million defense, you deal almost 257 million damage before weaknesses and crit multipliers; way more than the necessary 182 million!
The last issue is that, well, accuracy is based on your HIT and the enemy's SPD; if you only used your Valkyrie then you'd have about 60% accuracy when attacking from behind. Sadly there are no evilities that increase accuracy, and you can't increase your HIT stat without better equipment... The only way to reliably boost accuracy at this point is by having a second unit with the Assist evility in order to force it to 100% accuracy; thus you'd need to take out this second unit, target any bear, then move your Valkyrie behind the bears and use the Capture 3 skill. Set up correctly you should have 100% accuracy and one-shot all nine bears, and therefore guarantee their capture!
Then just run the map 200-ish times (making sure to subdue and extract before the prison reaches 128, so I guess go back every 10 runs?), and combine all the extracts, and you should finally have a capped extract of 10 million bonus stats!
