So far, love the mod and the new skills. I like the idea of a heavy support tree like this. I wanted to note any bugs I come across so you would be able to work on them later. You already are aware that skills from this tree cannot be cherry-picked at character selection like other starting classes. You also seem to be aware about the use of Jingle giving healing to Undead allies which is no bueno...

I've also spotted one more:
-When utilizing Jingle, there are random buffs that can be given which are broken. Almost every insatcne I've seen where a buff given was not working correctly was a type of aura buff. I've received Healing Tears on 2 separate instances through the use of Jingle, once on the character casting Jingle, and once on an ally. Both instances the Healing Tears did not heal the character who received it, nor did it proc an ally who walked up to the person with that buff to heal. So no matter how you look at it, Healing Tears did not work (whether it was supposed to heal the person who got the buff, or work as the skill intends which is to heal an ally who approaches the one with Healing Tears.)

-Another instance of Jingle giving a buff which did not work, was when it gave a buff (cannot remember the name) that sets any enemy who approaches you on fire. I used Jingle during Act I when still on teh ship during the voidwoken fight on the top deck. It gave me the buff, then the voidwoken took their turn to approach me in melee range, neither of which were set of fire. I think as it is, Jingle has some sort of problem with "Aura Buffs".

Possibly it might have something to do with the original skills setting the aura parameters ranges? It might not be innate in the buff what the range it provides.

~It would be fantastic of you to look into it! Thanks for the hard work and the great mod!~
