well, previously it was giving +20% nrg & +10% stm & they were allowed to have 4 in one cell but now everything is reduced

its 5 per cell, and it was changed to include the HP changes. We're always modifying amenities to balance things out- nothing new there

HP:

-12078

lol & my total is

10,190

now my strength is 0, while speed is -8868 lol

hmm, you should'nt be able to go negative

lol, this means i will die before someone hits me?

just removing these and don't look to worthy now

logically, they should've been training-only objects anyways no? That's what cell presets are for

I do like the other coal effects better (of course lol). I like that there is a tradeoff between a lot of benefits for training but reducing stats, but now its really not worth the trouble. I think if it reduces your stats to 0 it should more benefits like it did before (I think at one point it gave 30% nrg and either 10, 15, or 20% stamina, I cant remember though). Now you are probably better off not using them at all.

When i have 5 Bag of Coal i should have 5x20% energy but, 

I have 12 enegy ( my lvl ), and 100% so it should be 24 and it is 22 ??

it's always calculated off your base stat. So 20% of 12 is 2.4, which would round down to 2 and 2x5 = 10. So 12 + 10 = 22

sorry guys, had to change coal again. Having the HP reduced too much causes issues (like winning a battle and not getting EXP) and messes up the gang functionality
