Auto-Sell Special Artifact Rewards
OMGclick can be used to quickly determine whether an artifact received outside of typical battles (e.g. Clan Boss chests) is worth keeping or should be sold.
When receiving artifact rewards outside of typical battles, if OMGclick is running, click on the artifact to view the artifact details window. This will trigger the auto-sell routine, allowing OMGclick to run the artifact through your auto-sell settings.
As of this post, this functionality does not work properly when more than one artifact is received at the same time, such as when receiving arena tier rewards. If you wish to see this supported, consider adding it as a Feature Request, and get people to vote on it.
