Hullos.

The Squirming Embrace:

... cause a swarm of worms to squirm over the grappled creature. These worms deal automatic swarm damage with no attack roll needed (see the table below)... ...A Worm that Walks can only have one embraced target at a time, but it does not have to continue grappling in order to maintain the embrace...

The damage table for engulf is based on HD. I assume the HD is question is equal to the Worm that Walks - if not, where is this HD value obtained?

When does the squirming embrace damage hit? As soon as the creature is grappled? Once a turn has passed? Only once or every round?

Thank you for your time

It is based on the Worm that Walks' HD.

Squirming embrace should do damage as soon as it appears and then every round you maintain (don't dismiss or move away) it on your turn.

Thank you for clearing that up
