Dark souls 2 soul memory calculator

10 May 2025 Author: Erik Lievaart I've played quite a bit of dark souls 2 and getting coop to work can be quite confusing to people. There's a number of restrictions that have to be checked when two players cannot see each other:

summoning checklist

platforms must match (pc, ps, xbox)
game variant must match (vanilla / scholar of the first sin)
region must match, or cross region play must be enabled
covenant of champions blocks all coop
neither player must be soft-banned (or both)
the game blocks coop on too many disconnects; use bone of order to restore
coop is prohibited in some areas (things betwixt, saint's grave, doors of pharros)
don't wear name engraved ring, or both wear the ring with the same god
the host must be human, the phantom can be either human or hollow
host must remove human effigy effect from bonfire (if present)
there must be a boss in the area (or use small white sign soapstone instead of large)
no more than 2 phantoms (including NPCs); 3 for scholar of the first sin
soul memory must be in range (see below)

Please note that you can use ds3os private servers which allow you to disable soul memory restrictions (pc sotfs only). In all other cases players can only see each other if their soul memory tiers are in range. This page contains a simple soul memory calculator that makes checking the soul memory requirement easy.

Last 4 columns in the table above show the limits of the large white sign soapstone.
They show the minimum(incl)/maximum(excl) SM of summon signs seen if the player is the host.
The small white soapstone can reach an additional tier both ways.
