I ask the moderators to attach a vote on the following issues:
1. How many times can you use Double Damage (1 or 2)?
2. Is it allowed to upgrade Psions?
3. Is it allowed to upgrade Phoenixes?
4. Is it allowed to upgrade Vampires?
5. Is it allowed to upgrade Fairies?

Maybe I missed something – please add to the list.

1. On HL maps, 2 Double Damage is 100% possible; on L+U maps, it's questionable, but I'm inclined to think it's also possible. One thing is certain: it either exists or it doesn't:smile50:!
2. Yes, it's allowed.
3. Yes, it's allowed.
4. Of course, it's allowed (considering skeletons aren't raised in every battle:) )!
5. I don't understand at all why it's not allowed?????:confused: considering that you need to build a resource depot with 5 of them beforehand.
