First off, this mod is freaking AWESOME. This is one of the best mods out there

I have a couple suggestions for the next update, however;
I think an option to disable blood would be nice, in addition to a command that allows you to remotely add and revoke skills.
I think an option to auto-switch into combat mode when you are attacked by a monster would be nice so you can respond more quickly, and maybe add some animations for equipping armor and/or totems of undying.

All in all, this is a great mod, and keep up the good work :)

Also, skills retain upon death if keep inventory is on would be nice

You can use the /gamerule keepSkills like keepInventory command.
