PVP Rework

This update brings us our first ever PvP overhaul. It introduces...

• PvP Seasons

New leader: Old Murk-Eye

After a long time comin' we finally have our first murloc leader! Old Murk-Eye charges into battle as the third Beast leader! He floods the board with waves of scaly tidehunters to overwhelm his opponents and grant him victory over the depths of the battlefield.

Passive - March of the Murlocs:
For the next 5 seconds after playing Old Murk-Eye, spawn a Murloc Tidehunter at your base for each Gold you spend.

He also comes in with two new talents:

• Marathon of Murlocs - March of the Murlocs lasts an additional 5 seconds.
• Tip of the Spear - Murlocs spawn at Old Murk-Eye instead of your base.

New Talents

As a testing feature, some minis will have their 3rd talents introduced early. These include...

• Carine - Cairne Resurrects once at 30% Health.
• Tirion - On death, heal one nearby ally to full Health.
• Harpies - Infectious Swipes - Harpies gain Poison.
• Smoke bomb - Apply Stealth to enemies as well.
