So, there's some tricks to the map generation. Most of the time one of the wizards is in Myrror and is also right on top of another wizard on 4 players. They can be on top of you, but it's pretty rare. Much more likely to be one of the wizards close to you.

I've taken to going and checking Myrror on the first wizard I run into in my test runs and this is the first time it's paid off. It saves a ton of time, but can be risky as the Shadow Demons aren't particularly hardy in close combat.

Thinking back, I probably should have immediately sent the Wraiths to Freya and not gone in with the Demons. Freya is always a pain and I kinda knew where the last wizard would be based on land layout and could have used them to double check Myrror for another player if my assumption was wrong. I think the Demons would have finished off Talic easy and probably would have allowed this to be sub 4. I got lucky with the last two Wizards not being able to return though! I honestly was expecting to have to hunt Freya to no end.

Ah well, at least this proves the Demon strat works.
