                         MAX LVL MIN LVL REQ MULTIPLIER

RANK 2 ---------3 level 20 ---------- 2x2x2 (6)

RANK 3----------4 level 30 ----------- 3 x 3 (9)

RANK 4 ---------5 level 40 ---------- 4 x 4 (16)

RANK 5---------- ----------- 5

EXAMPLE rank 3 needs 4 LEVEL 30 heroes and 12 level 1 rank 3.

THEREFORE rank 3 needs 16 heroes to make one rank 5.

Multiply that by 5 and you have what it needs to rank up to 6. 

it may be better to devise it backwards like say rank 6 needs 5 rank 5.

Rank 5 needs 25 rank 4's.

Rank 4 needs 16 rank 3's

Rank 3 needs 9 rank 2's.

Some thing like that. lol..... 

Anyone this is a bit messy if anyone wants to hash it out be my guest. Crazy numbers. 

I think you made a mistake some where.

A rank 6 needs 6 rank 5's.

I created this table to know everything necessary to upgrade a character to rank 6, it is in Spanish, but it is quite intuitive.

very nice table!!

what is comida?

Comida means Food in Spanish.

Also there is an English Chart which was made by a youtuber named Chofly.

Cholfy did a video about rank 6 heroes.
