Introduction: What I hope this guide to be is a quick and dirty guide to the value of farmables in comparable terms. My guildlines will be stamina cost to reach 100 luck. I will exclude common items and include more annoying or difficult to obtain items. I will assume the best use of stamina so if it's better to farm a Kino to 100 luck vs obtaining additional items in a quest, I will use the Kino. (Next to the name is how much energy for 100 luck) Assumptions: Ignoring job cost unless there's a huge difference in the normal 10-20k a job and 20-30k a recode. I'll just note if there's a position or negative coin gain from farming. Ignoring coin cost of normal PoFuck monsters. Kino/8-bit 1 is 1 ^ drop for 1 luck a run. Ignoring team builds limitations. Ignoring luck chest drops. Ignoring Trading post items. Cleared PoFuck. No treasure hunting or negotiator team members. Not doing the math on leveling them up. Most of these units cost the same to level up. 1 energy = 121 stamina. Baseline Lucia 4 (20 energy): 1.44 luck for 40 stamina assuming 1.6 lucky orblings a run. Value 0.036 luck/stamina with 0.005 luck/stamina for running the stage. Net coin gain. Total 0.041 luck/stamina. Baseline Easy Recode (23 energy): 20 energy + 400 stamina. 2820 stamina. Net coin loss. Total 0.035 luck/stamina. Clara^ (26 energy no arena metal zone 6/7): 3 Recodes 240 luck Kino and items ~3300 stamina +5.25 luck on natural gains. Not sure on coin cost. Total 0.032 luck/stamina. Note: When arena metal zone 6/7 are open, it is less stamina to recode Clara 5 times obtaining 40 luck from the Kino. Ella ^ (24 energy): 103 runs at 30 stamina, 3090 stamina +15.5 luck on natural gains. Net gain on coins. Total 0.037 luck/stamina. Quick message about Ella here. She's a farmable 100 luck kiss bottle. Think about that for a second. Let it sink in. Shin'en^/Mutoh^ (32 energy): 200 runs at 25 stamina each, 5000 stamina + 30 luck on natural gains. Net gain on coins. Total .026 luck/stamina. BLO^ 6 recodes (39 energy): ~4800 stamina in materials and obtaining the job 3 unit +3 or more luck on natural gains. Net loss in coins double normal recodes. Total .021 luck/stamina. Lucia^ post Lucia 4 farming (15 energy + 50 in Lucia 4): This one is a little weird. If you spent ~50 energy on Lucia 4, you will have the items to recode her 20 times. There is an additional stamina cost though. I'm going to assuming you run Lucia 4 twice since you clearly liked spending energy enough here anyways (and ignoring luck chest). ~3100 stamina + 73.1 natural luck gains. Slight coin loss. Total .056 luck/stamina. Nia^ (I don't remember event statistics, just farm her anyways): Another weird one. Nia is apart of a trading post event. This means for all of the time you spend running it, all of the stamina is traded in equal value for items. She's also one of the highest coin/stamina stages in the game. Just farm your 3-5 days of weekly trading post for 3 weeks, sell or use the buddy drops, and level up your free 100 luck unit. Echo^ 6 recodes (43 energy) ~96 runs at 30 stamina each + 1800 for the helix. ~12.8 natural luck gains. Total 0.024 luck/stamina. Personal note about Echo^. She does a hell of a job replacing Gego^. I feel no need to put any energy or stamina into making Gego^ 100 luck now that I have Echo^. There are a few niche differences, but nothing that would be a long term impact.
