When the Siren Spitter's acid lands at range it goes across your gun deck, and every broadside is ×0.8 of itself for a few turns. The debuff outlasts the hit that applied it.
The tell marks the blow that carries acid and says at what range it counts. Up close it has other ideas, and those are on the tell as well.
What to expect
- Siren's Wax makes acid do nothing. Spitters lose heart. It is the only monster with its own fitting.
