Yesterday: the quicksilver figure that remembers you

What it is

A figure of living quicksilver taller than a house, risen out of the shallows. It is based on mercury, a metal that is liquid and a perfect mirror.

Where and when it comes

On the shores of ocean worlds: the Anemone Strand and the Tubegrove.
It rises out of the shallows 20 to 30 metres from you.
After one is slain, another cannot come for about 30 minutes. The Codex hint is "Silver footprints that were not yours".

How it remembers

Nothing you do to it now can touch it. But ten seconds after you do anything near it, a silver echo of you climbs out of the sea and does the same thing. Your echo can hit it. Your echo hits you too, so mind where you stand.

Each echo reaches about 3.4 metres and hits for 16 damage.
A blow your echo swings within reach of it lands on it.
Up to four echoes can be out at once, one for each of you.

How the fight works

Lashing. It lashes whoever comes close.
Ringing. It sends a ring of liquid metal spreading over the ground. Jump it.
Echoing. Strike where it will be, and draw it to where you were. Your echo's strike is what lands.

Tips

Plan ahead. Think about where your echo will be ten seconds from now.
Group members can each make an echo. Four friends means four echoes.
Stand back when you are not striking. The echoes are a danger to you too.
