Also, I can't believe you used a scroll on your amulet of life saving XD
Aside from the obvious (those in the main chamber of the cathedral) you need to watch out for the smith. He is surprisingly formidable and what he lacks in equipment he'll make up in survivability. You could take him out first, then use the bottleneck of the cathedral to your advantage (don't take my word on this, I've never even gotten Elpuri's head back to Petrus, let alone kill him). You'll need some way to detect invisible units too.
Z: Maybe I just don't have the latest 3D + Sound version
4zb4: Go for 3?
EDIT: Yes, I just checked it, the latest 3D + Sound does have Blob's art. My mistake.
EDIT: I've just consulted Kahvi about this, he will go through the variants and give us a list of approved features. If you're wanting to do this, I suggest looking up the pieces of code for the new things in the variants so you're ready to go. Sit tight in the meantime.
If this is to be done, a few things need to be run through first.
1. Authorisation from Kahvi
2. Permission from authors
3. Analysis and balancing, simply throwing the lot into one won't do
I recommend using the latest CVS version that has Blob's artwork as the basis. It should then be put together with Z's 3D + Sound version. These add to the experience without adding anything to the game. The others should wait until point 3.
