To easily win over an enemy keeper, transfer a level 10 mistress to the next level. Super-early, tunnel into his domain and introduce your lady to his imps. She'll lay waste to them in no time (lightning rulez!) as well as to any low-level monsters he attacks with (even if there's lots of them attacking), thanks to her drain spell.

Without gold, your enemy is toast! No imps - no gold, and you've WON!

Also, throw out crappy monsters such as flies, spiders and trolls as soon as you can get better ones. A locked door at the portal prevents monsters you don't want (such as trolls, who don't fight very well) from entering.

One way ticket: "From Barracks to the Enemy Heart"!
