So, the 100x power Runic Mace bug was luckily fixed last patch, but the other extremely noteworthy overpowered equipment still wasn’t despite it being stronger. While a lot of them still need rebalance, Bone Ring is one of those extreme outliers that is even more overpowered than Runic Mace pre-nerf.
Bone Ring at rare currently gives 5 mana per skull on starting board. There are 2 rings slots, so this is 10 mana per skull on starting board. This at rare combined with other mana starts can easily hit over 100 starting mana at the start of battle.
There are a couple issues with this, but one of the most noteworthy ones is it is literally impossible to make 1st place in PvP unless the player owns 1-2 Bone Rings. This is due to Bone Ring allowing a 0 turn win due to all spells starting at full mana allowing for the full 2500. This is an intended mechanic, but pretty sure it isn’t intended for something as low as rare to be able to do it, especially since most other mana start equipment in the game does around 90% less mana start than Bone Ring (For example, Dragonguard Helm gives 6 starting mana, which is less than Bone Ring at only 2 skulls). The current PvP meta is have 2 Bone Rings in every single color and then auto win first in every category completely uncontested.
The other issue this presents is it is possible to win any battle, even outside of PvP, on turn 0. The player doesn’t even need to touch the board to already have every spell operational and ready to go. While this would likely be possible later in the game even after rebalance, this can currently be done with enough luck with as little as 1 rare Bone Ring.
Currently Bone Ring is balanced at 5 mana per skull at rare and likely scales 5/10/15/20 based on rarity.
Bone Ring should likely be rebalanced to 2/3/4/5 or 1/2/3/4 mana per skull on starting board.
