Difficulty doesn't affect the damage you make to enemies. But I think it was indeed "glitch" or bug and Ull took 2 times damage from the same icicle. You can see the health bar decreasing in 2 steps. Edit. A correction. The only thing that affects enemy health size is Survivor mode. On Survivor, there's less health for Ull, Batari and the epic beasts. And this player is on Survivor, so that's how they kill Ull with fewer icicles too.
Lovely screen. I got a lot more stuff in case of, but i also went with cherry lol. It was around 1400 with four screens (one display), two full acrylics, four half acrylics, two full mags, four half mags, two storage towers, two sets of cubbies, one tablet tray, five sets of initiative trackers, a lot of dm trackers... the box was so heavy when i recieved it lol.
And if you aren't satisfied, they will get you a new one. I have a dm screen that got debunged. I'm waiting for it to do it again (I threw some pva glue into the hole) but I could have absolutely gotten them to send me a packing label and send me a new one. Craftsman's Promise and all that.
