Zulrah attack delay

Currently zulrah gets a free attack in before you can change your prayer because there's no delay after it changes location for the attack, so you cant actually which one it is before you get hit.

Fix: Add a 200-400ms delay before Zulrah continues attacking you.

Just want to say this doesn't make Zulrah unreasonably hard or anything it just makes it annoying to deal with with low defences, for max gear people it won't matter really.
