Blood Weapon needs changed

[ArthurATDayne]

I suggested this in the Dark Knight Megathread and I'll suggest it again...

Suggestion: Level 90 Shadowbringer= Upgrades Blood Weapon to Shadowbringer, 2 Charges of Line or AOE attack OGCD, 60 seconds CD, usable under effect of darkside or mana < 3000. Each use of Shadowbringer Restores 25-50 Blood/1500-3000 Mana.

1. Feels like a huge upgrade DONE
2. Feels like my hardwork and patience getting to 90 paid off DONE
3. I can regenerate Blood/Mana and blow up enemies, Satisfying! DONE
4. Interacts with and benefits my whole kit, part of my rotation in a meaningful way DONE
5. No need to keybind a new skill, no need to change my hotbars. DONE
6. No need to Mash that Keyboard 3-5 times to get your blood/mana back before durations etc run out DONE
