- Which faction is stronger? (Necropolis, Tower, or Conflux)

Conflux is a very strong castle. Much of its strength comes from its magic and resistances. Plus, it has very fast phoenixes. And on small maps, mages and elementals won't have enough resources, and it will be difficult for them to deal with the Necropolis and its skeletons. Although the Necropolis loses the vampire bonus and partially the dragon bonus (there's no one to lower morale).
