@Yuri850: I think the best level is "The Underpass". At least, that's where I got the quest, though I'm not sure if it was the normal level or the heroic challenge. If you check the first few pages of this thread, you'll find some screenshots that'll help you.
@Kris19275 The Popular BBQ quest (set 20 enemies on fire at the same time) has been discussed a lot at the beginning of this thread, if you want to read it up. From what other users reported it appears the best place to get it is the level called Underpass. Build DWAARP towers and give them the ability to set enemies on fire.
The Assassin's Guild is one of the two advanced upgrades of the barracks tower. Get that upgrade, max the assassin's ability to dodge attacks, and wait. The more assassin's guilds you have, the faster you will reach 1000 dodged attacks.
