is there going to be an adjustment for the Maretta for deaf people ? Guildie cannot hear it so pretty much 0 chance for her to find it.

Quoting myself from another post on the same topic:

"Also, the siren seemingly has set spawns. She spawns close to most bartering NPCs and sea monster icons. The spawns away from these things are not the norm. You can find this resource on the Sailing Discord server as well as some kind sailors that do call out when they slay her on that specific server. Not everyone does it, but at least you will see what servers to not waste your time on here and there."

Mayhaps these links will help your guildie in the meantime.

100% agree

We need a visual notification as well for those who are hard of hearing, deaf, or simply play without sound. Hope we can bring this to their attention!

Totally agree. There should be some sort of visual indication as well.

In the meantime, though, if it were my guildie, I would offer to sail around with them so they can get the drops they need.

Unfortunately do I have to raise the Parity clause of EU regulations on this one ?
