In the second scenario of Sword of Valor it says that when you defeat the first villain, banish him and summon the second villain to a random location. The scenario is won when you defeat and corner the second villain.
I am wondering if you need to only defeat the first villain to banish him, or if you have to corner him as well. I would think that you need to defeat the villain just like you would any other, cornering him to make sure there is nowhere he can escape to in order to banish him. But the wording regarding the second villain is very specific about the victory - defeat and corner.
I have been playing it that I need to defeat and corner the first villain and not simply defeat him, and I have yet to get past this scenario. Some clarification would be appreciated.
Compare to B-5, where Thurl+Inhaz needs to be cornered and defeated before you spawn Tancred; in 2-2, "merely" defeating the first villain is enough to spawn the second. :)
