New Winter Gem in Game of War
The new Candy Cane gem is great. It is the same boost as a Troop Health gem (which is one of the best gems in the game) but uses the 4th gem slot. This allows a total of 50% health boost from gems per item which is a very big upgrade (the current best standard combat gear only offers a 40% boost). Grab as many of these as you can. They are not easy to get hold of but they do appear in the current holiday gifts and from the Krampus Monsters.
