So I'm gonna sum things up about a change that will be going through next patch. Now before you get pitchforks about Hirez taking things away, take a minute to understand why they are doing this.
Next patch, completing 2 weekly quests will no longer reward 30 gems, and instead they will greatly increase the amount of favor rewarded for them. This change is being made because of the overabundance of currency without anything else being done to counteract it. Early a possible 80 gems every week also made it very difficult to work Gem Storm events work, which have been a long recurring thing in the game. Both of the systems will function and remain the same with Daily Logins having the same values and Weekly Quests having free reroll amd Favor Rewards.
With that out of the way, speak of the devil we have a gem event this weekend! From March 18-20, winning three FWotDs will reward you 30 gems (once per day). Double EXP, Worshippers, and Favor Rewards. This will be on PC, X-Box, and PS4.
