Since quadrupeds aren’t plausible in Don’t Starve, i made a human-doll Raggie character creation screen. I had the idea of her Hagsword ingame growing stronger after every kill, and you can save up that power for a big hit (Save it for a boss, 1hit a weaker monster that will flee or even things like 1hitting a spider lair)
It would need a downside, so maybe you have to frequently use the swords charge otherwise it’d explode (In order to prevent you saving the attack forever)
