I'm working on my BBEG for a campaign I'm running. The PCs have met the BBEG before and know that he can cast teleport, so they plan on Dimensionally Anchoring him at the start of the fight.
I'm trying to make the BBEG still be able to teleport around the battlefield after being dimensionally anchored to keep the party on their toes. So far the only things I have come up with is Shadowdancer's Shadow Jump and maybe Abundant Step.
I wanted to make sure that Supernatural Abilities like Shadow Jump are not stopped by Dimensional Anchor. Also, I was wondering if someone using those abilities could use them such that only they go along (in case he gets grappled) like a level 20 wizard choosing to only shoot one magic missile.
