Several months ago, I was trying to think up how to make the Bloodstone (I call it the Bloodstone, since I'm pretty sure something referred to it as that in-game, and 'Artifact' doesn't sound nearly as good, lol), and I could probably make it exactly how it works with a timefreeze, invulnerability, several fake inventory items, and an extra A_JumpIfInventory in the fistsTenement Funster wrote:As for the demon artifact from ROE, maybe you could make it charge up through killing any kind of former human, and when activating it's effect, maybe it just gives you berserk and a speed boost or something... could you pull off an effect that slows time in Doom?

If someone could get sprites, I could release it as a completely optional add-on wad.
