location of boss?

Hi, I'm fairly unskilled with the MA, have made a couple of arcs, short ones.

I made a one-shot Halloween themed mission, just a little fun, used one of the DA graveyard maps, firbolg minions, clickables. One group of clickables spawns an ambush when complete, the other spawns a boss. The boss is a requirement to complete the mission.

I've tried having the boss placed at front, back... the one complaint I've gotten a couple of times is that the players couldn't find the boss. I've run it numerous times and there's no reason or rhyme I can see to where she spawns.

I thought front would be best, expected it to be close to the mission door but it seems to have no relationship. I've had her set to load at the back, but again, I can't see the reason/rhyme so I can't write clues for the players.

I tried switching from one to the other of the DA graveyard maps but it doesn't make any difference. They are both multilevel maps.

Has anyone run into this issue? Anyone have any suggestions or clues how to handle this so that the location is more obvious, or more predictable?

Any help or suggestions welcome.

Graveyard map? Is it an outdoor map? Cuz if so, those don't HAVE a defined "front" or "back", as far as I know. So in other words, it'll be completely random.

When I do an outdoor map, I try to always have the boss and the surrounding group doing some kind of animation. The extra movement can help make them stand out more. If you can fit in either the flashy green casting or held animations, that is even better. Unfortunately, that doesn't always fit.

Dont think there's any way you can have it more precise than "out there", which always is confusing to the players.

You might want to jump the bandwagon of requesting an option for boss fights to spawn as an ambush.
