🍗 Raid: Shadow Legends Cascade Food Calculator

Calculates the TOTAL number of champions of each rank (starting from Rank 2) needed to cascade-feed your main champion, "food on food", from its current Rank up to the target Rank, plus the estimated energy cost. Rank 1 is not counted here as a starting point for the cascade — not because it "doesn't count", but because leveling Rank 1→2 is inefficient when you usually have plenty of 2★ champions straight from Shards.

Main champion's current Rank: Rank 2 Rank 3 Rank 4 Rank 5 Target Rank: Rank 3 Rank 4 Rank 5 Rank 6 (max) How many champions of each rank do you already have in reserve (duplicates)?

Only count SPARE champions (besides the main champion you're ranking up) — i.e. duplicates you could feed. Reserves at a given rank reduce the need to grow food from scratch, and that reduction cascades down, lowering the need at lower ranks too.

What LEVEL is your MAIN champion at on its CURRENT rank?

This applies ONLY to the current rank — after ranking up, the level resets to 1 anyway, so at higher ranks we always calculate full leveling from scratch. Leave it at 1 if the champion is fresh at its current rank. Enter the level (visible in-game on the champion's card), and we'll calculate the remaining XP to max from the XP curve ourselves.

ℹ️ Super Raids do NOT affect these calculations — it's 2x energy for 2x XP (and 2x silver/loot), so the XP/energy ratio stays identical. You only gain time (fewer clicks), not energy efficiency.

Calculate cascade

Result

Total plain Rank 2 champions needed "at the base" (after subtracting reserves):

Self = the champion that itself ranks up to the next rank (not eaten, but still needs leveling — see energy). Food (fresh) = units of this rank you still MUST obtain/grow, after subtracting reserves. Reserve used = how many of your declared spare units went into this rank. In the row matching your CURRENT Rank, self is 1 lower — because that's your already-owned champion doing that promotion itself, so the rest calculated there is pure food.

Estimated energy

Total energy needed (leveling the main champion + the entire food cascade, after accounting for reserves):

How this is calculated (cascade logic)

• To build ONE champion at Rank R, you need a champion at Rank R-1 (which gets promoted) + (R-1) champions at Rank R-1 as food.
• So a total of R champions of rank R-1 "disappear" (1 gets promoted, the rest are eaten) to produce 1 champion of rank R.
• We calculate TOP-DOWN: from the target Rank down to Rank 2, at each step subtracting the declared reserve, which cascades down and reduces the need at lower ranks.
• The calculator also subtracts the "cost already paid" at your current Rank (since your champion is already there), so it only counts the ADDITIONAL food needed from now on.

Energy: only the champion that actually GETS PROMOTED at a given step (self) needs to be leveled to max — food can stay at level 1, regardless of whether it was freshly grown or came from your reserve (reserves only save the cost of GROWING, not the cost of leveling — since food never needs leveling).

XP/energy rate: ~1,080 XP/energy is your real measured rate from 9 full Brutal 12-3 runs (72 energy, no Super Raids) — the rate held steady in the 1079–1082 range throughout the whole sample. Super Raids don't affect this rate (see the note above).

🏆 Already at Rank 6? Calculate just the leveling

Rank 6 is currently the highest rank in the game — there's no further promotion from it, so the cascade above doesn't cover it. This is a separate, simpler case: just leveling 1→60 (2,010,669 XP to max, per AyumiLove and the RAID Wiki).
