I don't really have a plan when moving. I start spread out and then just move around. Is there an optimized pattern I should be using?
FoD is a deduction/guessing/meta-game through and through. What do you think the Dracula player will do, what approach does he normally take, is he a wild card or set in his ways player? What would you do if you were Dracula once you see the Hunters spread out?
Doubt there is an optimized pattern, but I do think you do need a plan right from the get-go. Don't go around the map just randomly, each Hunter should have their initial placement and subsequent turns very much planned ahead as to where each will go. Do you do a 'W' in Spain for example, that should find a location on Dracula'sTrail if he's been there. Sideways 'W' in Central Europe? Ireland/British Isles are easier to remove from the picture by having a Hunter start there and spend the first few rounds looking there. Eastern Europe (and Spain) can be cut off from the rest of the map for Dracula with Heavenly Hosts and Consecrated Ground.
As for Evasion, the first game he got in around the 3rd turn, and the second game he did get it later. At what point do I stop drawing Event cards? When I am full up and have a decent spread.
It's one of those questions where intuition and experience will tell you. If he gets Evasion early, no need to stop drawing until the deck exhausts, with all the Newspaper Reports, etc. that will reveal locations in Dracula'sTrail, you should get a sniff of his tail sooner or later, then it's just a matter of hunting him down. If the Evasion doesn't come early, if you have locked Dracula down to a particular area of Europe (Spain, Central, Eastern, etc.), I would stop drawing and close the net around him. Have Stormy Seas ready in case he hits the seas (can really hurt him if his is in the Black Sea).
