New Defensive Building Idea: Witch's Cauldron
In my mind, this will be a 2x2 building and can be either be treated as decor (will not have the white 1 space border) or as a full defense/building. At first, I had the idea of it having spawn skeletons but that idea has been taken up by coffins.
Back to topic, this cauldron will have an AoE damage that has a range of 5 tiles. The main attack is the poison/damage fog that deals 15 dps (or less) on Level 1. This is a deterrent to the mass skeletons the L2 witch (or possibly a future L3 witch) can spawn. Like all defensive structures, this will require gold to upgrade but the fuel source could either be elixir or dark elixir (whatever balances it out). The trigger area (to activate the cauldron) will be 4 tiles.
Furthermore, I think this defensive structure will be much more important in war, maybe add another difficulty level of doing a GoWiWi or someone using mass witches only to face a skele killer.
**Side Notes: have not figured out HP yet but have ideas. I am thinking somewhere around the HP of a builder's hut, just a smidge higher HP. I do not want this to be super annoying and be a sturdy rock for troops to get stuck on. This will be a one-hit kill for lightning spells for sure.
