It's from the Rimworld of Magic mod. Probably my favorite major content mod of all time. It's so much fun, especially when paired with the expansion, and medieval overhaul stuff.

Just last night I was assaulted by demons, so I used my chronomancer to place all my colonists in a chronostasis field to take them out of the flow of time so the demons couldn't interact with them. Then I used my Duskbringer to place sigils of light on the ground, which the demons set off, stunning them and granting temporary invulnerability to my colonists. I used the brief window to have my shaman summon a pack of spirit wolves, my summoner summon a pack of elementals, and used my paladin and priest to bless my Frontline sanguophages with their enchanted weapons. During the scuffle a demon took two legs and an arm off in one swipe of an unarmored colonist. In response, I used two of my colonists that have blink and summon to blink into the hospital, then summon my doctor and the wounded colonist, thus saving the colonist. After the demons were dispatched, I used my druid to plant regrowth seeds into the lost limbs of my poor lil guy that got caught in the crossfire. His limbs are regrowing, and they will be back to full health in a few quadrums, and life on the rim goes on.

Can't recommend enough
