I noticed that there didn’t seem to be a general consensus on how food costs grow in relation to hero/troop level and rarity. So I thought I’d post what I believe seems to match the game’s internal mechanics.
HEROS:
Where x = current hero level
1*
1000 + 20(x - 1)
2*
1200 + 24(x - 1)
3*
2100 + 42(x - 1)
4*
3000 + 60(x - 1)
5*
5000 + 100(x - 1)
From what I’ve gathered, food cost is not affected by ascension tiers, but rather only by the level that hero/troop is at in that ascension tier. Here’s an example: you have two 4* heros at different ascension tiers and levels, say 2/31 and 3/10. The first one would be calculated as follows:
3000 + 60(31 - 1) = 4800 food
The second one:
3000 + 60(10 - 1) = 3540 food
So in essence, food costs return to the base amount each time that hero ascends to the next tier and its level is reset.
TROOPS
Where x = current troop level
1*
5000 + 2500(x - 1)
2*
7000 + 3500(x - 1)
3*
9000 + 4500(x - 1)
(I don’t have exact data on 4* troops, but I see a pattern)
4*
11000 + 5500(x - 1)
I do realize that a hero’s food cost growth is a 2% increase per level and troop’s is a 50% increase. Writing out the formula seemed easier to visualize.
Hope this was helpful for those who might’ve been confused.
Thanks for reading!
