More than one enemy
Rifts range from Gravewake and Lost-Soul attacks to Hive fractures, Moonfang hunts, Plague Processions and the Eclipse Court. Their rosters can mix enemies; the first creature you see is not necessarily the whole invasion.
Counter the pattern
Soul undertow marks a ring with a calm eye. A ground-cleaving surge calls for a jump over its lane. Closing hexes demand movement out of the circle, falling prisms demand a sidestep, and Moonfang sweeps demand a leap. Read each actual warning instead of relying on color alone.
Keep the frontier promise
NPC commissions can ask for fresh rift waves or the final named seal. Accept a local commission before the work: unrelated encounters do not retroactively satisfy a specific promise. Withdrawal and death can leave different consequences from a completed defense; the journal preserves that distinction.
