I second this, this mod is quite possibly the best health display mod and it sucks it's not in single-player.

+1 Would love to have this in single player

If someone knows a way to make DS display those healthbar symbols properly, I will post a DS version of this mod

To test it, you can type the following code in console in DS:
print("♡♥○●□■◇◆☆★")

Symbols are cool but they are only for esthetic anyways. Health shown in number is good enough for me. So if you can do that at least, it would be really appreciated.

I know there are already other mods that show health in number but in those mods you have to hover your mouse over the target, which is quite lame and distracting during a fight.
