The unit i currently got are
Protector 1*
2* training cost 5 000 (which is x10 the 1* training)
3* training cost ... i'm pretty much sure it's 12 500, i was owning a2* on the fr but my account got screwed so can't confirm.
Argeus 1*
2* training cost 24 000 (which is x10 the 1* training)
Fairy warrior 2* (i'm perfectionist to madness, i want the weaker one to be the older, so i'm recruiting the units needed for H dungeons so than once i'm full Tos / Ral, the 10 units needed for H dungeons will all be on the bottom and in rank of the oldest / weakest to the ... erm ... the less old one xD / strongest) (Don't forgot i'm not english :p) Compared to Tos, making them 3* will cost even less than getting 1 Tos at 1* so making them 3* will make them go to insanly weak to a little less insanly weak x)
3* training cost 33 750 gold (which is x25 of the 1* training)
High Elve

If you spend 300.000 to hire a High Elf and 3,000,000 to give them one Advanced Training you have practically the same thing as Count Beran for 3,300,000 Gold instead of 10,000,000. You can get Three High Elves at 2 Stars for the price of one Count Beran.
So 2* training, also cost x10 the 1* training.
Tos
I already know the 2* cost 10M because of a post my Chief made on our private forum (When i was on the fr), he telled us to keep ... some weapon i forgot the name (maybe scimitar and two hand axe but not sure) because we needed it to train it along the 10M
While it make few units, it should be enough to understand why i'm assuming it also follow the rule of building when it come to Gold Cost but i already know it doesn't apply for the item and i'm too lazy to look if there is any ...
