edited to reflect corrected calculations
So we all know leveling troops is extremely ham intensive. And I don’t have enough 3* to feed to my 4* troops. I do however have an abundance of 2* troops. The problem is they only provide 90xp each. So i asked myself, “what if I level the troops before i feed them?”
Each additional level on a 2* adds 16xp. For 63k ham you can feed a level one 2* troop eight 2* lvl 1 troops and one 1* level 1 troop. This results in a 2* level 5 troop worth 154xp. It becomes cost effective to pre level these feeders to level 5 when your 4* troop reaches level 17. At level 29 you save over 1.3 million ham to go from 0 xp to level 30.
edit: Xp per level was accidentally doubled. The following table has been corrected and contains the correct values for ham savings, about half what I originally calculated.
edit: Table values corrected. In light of the corrected data, this method probably doesn’t save enough ham to be worth using for many players. So no need to read unless you’re bored or curious or have tons of low level troops to feed.
As more than one person has shown interest in using this method with 1* troops I figured I’d plug the numbers into the spreadsheet. I was pleasantly surprised. The ham/xp is still much higher than using 2 *s, but it will save you vs. using unleveled 1 *s starting at level 15 on your 4 * troops.
Feeding 9 x lvl1 1* troops to a fresh 1* troops brings you to level 4, increasing the xp value from 40 to 64.
