Here's a clip showing the crafting of a Time Dilation Crystal and using it combat to get the upper hand against a few critters.
The item system in Thunder Moon is one of my favorite systems. The tools behind it make it very easy to add new items, icons, effects and set them all up with cooldown timer groups and that other various things that make items tick. While the items in the first release are done at this point, I plan for content patches to include new & interesting items that build on what is already in place. Going to be fun!
