Sálmar, the Cursed Moonwane — move tells
Hallowgrove boss. What each attack looks like before it lands.
The fight is decided by adds, not damage. Three moves summon — and in phase one the add is a copy of your own character at your own gear level. Both phase-one summon tells happen away from her body, so a camera locked on the boss misses them.
One caveat, stated because the source states it: every mechanic here comes from a single published solo guide — the only one that exists for this fight. Treat it as one careful player's reading, not a datamined table.
