Stamina system is in place. If your unit has a shield, you can set them to "on guard" and they will use stamina to block attacks instead of going directly to their health. Sneak attacking an enemy with an archer is a good way to bypass this. (2 pics)

Battle Art System is in place! When you score a critical hit, the Battle Art will show up for that unit. (Sorry for the large gif)

Chapter 2 - In Progress

New Orc sprites, new orc walls, and some art of the Swamp Orc. (2 pictures)

Added tall grass that you can hide in.

Added deep mud which counts as difficult terrain for humans, but may have a different effect for others.

And a few tileset tweaks.

Choose your destiny! The game has been published.

Tall Mutants don't go down so easily.

Player can now build in the arena. I'll be changing the block created, but this is proof of concept

This and many more things coming. You can see a lot more of what's planned to come in the Discord.

(Sorry for not resizing the gif) As promised, here is the finished building set-up. Building costs 5 x material level. The only part that remains is the Save System which is easy, and a button that spawns the waves of mutants to attack in the Arena.
