When in the Old Railway Cave a.k.a the cave with the artifact of the depths DONT I repeat DONT bring a light pet it will make the seekers agro and try to kill you bring glow sticks instead they actually work.Make this popular so others don’t make the same mistake I did
When you bring your little lantern pet, or anything that gives off charge, into the area of a seeker, the seeker will double in damage and speed and will aggro towards you until the source of charge has depleted. Oh and they spawn in big numbers, so run for your life.
From my experiences I know that he best way to get rid of them is a glowstick. Just toss it away and they will hopefully chase it. Charge lanterns give them a weird animation that stuns them for a second, but then gives them the buff. When the oriphaces on its back open up and fill with light, they have the light buff. In my opinion they have terrible agro range unless you are giving off light.
They they get a 50% incoming damage reduction whenever they’re affected by the light from a light pet or light plant. So toggle those puppies to off to kill seekers quick! Just be ready to taco them back on if any nameless spawn.
