I don't currently run D&D, but if I did, I'd discard standard alignment in a heartbeat. It sucks at doing the things it's intended to do.So who keeps standard alignment, and who discards it?
Dungeon World is a useful place to start. Alignment there is a "carrot" rather than a "stick": if you fulfill your alignment move during a session (which generally should be doable), you get +1 XP. (You never need more than 16 XP to gain a level, so +1 XP is a lot.) Alignment moves are tailored to each class, though there are also some generic options. For example, the Paladin has the following official options.What do you use instead? Does this affect the standard cosmology based upon alignment?
Alignment is controversial, repeatedly shows difficulty in implementation and usage, and frequently leads to perverse outcomes. Better to start from scratch and try something else. Monsters and baddies don't need it, if they're worth opposing in context then that should be clear, and if they aren't worth opposing other than because of their alignment jersey, that in itself is one of the perverse outcomes.Thoughts and discussion.
Genuine question: Why couldn't the sword just be...murderous and corruptive? Why does it need to be "Chaotic Evil" specifically? What does labelling it "Chaotic Evil" do that calling it "tainted" or "corrupted" or "morally hazardous" would not?Use it. Since 5e has very few cases where alignment makes a mechanical difference, it rarely pops up -- but every now and again, it's important. My party just found a sentient Chaotic Evil sword, now being welded by a good-aligned character. Hijinks will presumably ensue!
