That's great! I learned how to use the relic (Atheon) recently as well. I was raiding with a random group and when we were teleported, no one had experience with relic. I told myself F it, I might as well learn and grabbed it. After a few times I'm now confident enough to grab the relic every time. In fact, it's fun (ground pound praetorians ftw). I'm still new to using the relic during the Templar fight, but hey one step at a time. I hope you keep raiding and collect some sweet loot.
