Since the second wing of ICC has opened and if you're happen to be a wielder of Shadow's Edge part of the quest weapon that leads to Frostmourne. You can be both invincible and have unlimited mana to play with. If you're a pally or in a group with a pally. Have them cast Judgement of Light and/or Judgement of Wisdom on the target.
Currently its proccing insane amounts of Judgement of Light/Judgement of Wisdom.
You can literally heal yourself like crazy every second with multiple procs of Judgement of Light and more mana than you can use with multiple procs of Judgement of Wisdom every second.
Here's a link to log showing the insane mana regen.
World of Logs - Real Time Raid Analysis
329203 mana with Shadow's Edge compared to the next person in line who only got 3196mana. Thats over 100 times more mana regen during that boss fight.
Could'nt get any pics since you must disable combat logs/ scrolling combat text or any addons that tracks procs since the crazy amount of procs laggs your computer out.
Warning: You MUST disable combat logs / scrolling combat text or any addons that utilize combat logs / scrolling combat text as the bugged procs will overflow your system and lag you out. Once you disable those, enjoy your OPness whether it be owning bosses in PVP or owning noobs in PVP.
Also there is a possibility that crazy JOL/JOW proc rates is caused by the soul stealing that you're supposed to do as part of the A Feast of Souls quest. I would recommend not completing the quest in case soul stealing is boosting the JOL/JOW procs.
