The vanilla bloodstain sprite is half the resolution (128x128) of the one if Dark Souls 1 and has a really bad transparency on it. This HD one is 512x512 and has almost no transparency artifacts.

This is a conversion of my Demon's Souls Style Bloodstain mod for Dark Souls 1, now in 2 versions: Fresh and Dried.
This does not change the green soul sprite, might make add optional file for those once I find the corresponding images.

Installation:
1. Choose your prefered style of bloodstain then add the corresponding "52d5b387.png" to "textures/DarkSoulsII/override" inside your GeDoSaTo directory
2. Make sure that you have set "enableTextureOverride" to "true" in GeDoSaTo.ini
3. Happy summoning!

Uninstall:
Simply delete the "52d5b387.png" file.

Special thanks to Durante for GeDoSaTo.
