Two ladders show up in November 2026 notes, and they are not the same system.
The shadow-rank writeup after Zero Update 2 lists shadow tiers as MR, MR+, GR, GR+, GSR, and GSR+. It says rank beats the shadow's name: a GR of a plain type outperforms an MR of a famous type.
The island-order writeup from the same day still talks about C, B, A, SS, and G shadows, then UN. Player tests in that writeup use A, SS, and M or M+. Monarchs' Night, on the official description, adds player ranks GL and GL+.
Use the label printed on your shadow and in the rank menu. Do not translate MR into SS yourself. This site does not have a developer map between those names.
Craft rule both writeups share
Feed six shadows of the same type and the same rank. The result is one shadow of the next rank. Unequip and unlock every copy first. Equipped or locked shadows are refused by the craft.
The shadow-rank note places this craft in the Guild Hall and gives this chain:
| Six of these | Result |
|---|---|
| MR+ | GR |
| GR | GR+ |
| GR+ | GSR |
| GSR | GSR+ |
Six MR+ make one GR, and six GR make one GR+, so a GR+ built only from MR+ copies costs 36 MR+. A separate sentence in that note says a full climb can take about 363 MR+. That number does not match 36, so this site does not use 363 in the calculator. Count six per step.
The island-order note adds materials on top of the six copies:
| Merge | Extra cost reported |
|---|---|
| Six SS of one type into G | 500 common dust, 300 rare dust, 70 tickets |
| Six G of one type into UN | 1,990 rare dust, 799 legendary dust, 149 tickets |
If your craft window shows dust, pay that window. If it shows only six shadows, do not add the dust from the other note.
Where to farm the copies
That rank note calls key dungeons with an FK system the practical GR source, and calls overnight Infinite Castle a poor GR source that is still useful for legendary resources. It names Shield and Eminence keys only as examples of keys you might already own. Pick the dungeon you can actually enter.
Reported boosts, not guaranteed rates: a rank-up title, a rank-up accessory, rank-up relics left at their base effect, and a rise potion of about 15 minutes. A title boost “up to 88%+” is the upper figure they printed, not a promise on your account.
Clear shadow storage before a long session. A full inventory can block new drops.
GSR caution
GSR+ is described as able to double a rank-up so an MR can jump tiers. That is a late chase, not the first craft. Build a stable GR or GR+ team before you sink dust into a double-jump setup.
