Blue Slime is an enemy found in the Witch and Hero series. It has a wide variety of different variations, but the main blue one is very weak and easy to kill.
Witch and Hero[]
The Blue Slime's appearance in Witch and Hero is found in the first level. They are easy to kill as they do not have much HP and are rather slow. They are rarely deadly, but can be an annoyance in later levels when they are normally used to defend stronger enemies.
Witch and Hero II[]
The Blue Slime's role in the second game is basically the same. Once again, they do not have much HP and do barely any damage. Their speed is certainly not the best, either, but if you aren't quick you might find them closer than you thought they would be. They give only one experience point and two gold when defeated so going out of your way to kill them for their rewards is not the greatest idea unless you are just starting out or you are desperate for EXP/Gold.
