The runes in League of Legends allow you to customize your character for meaningful effects that change up the game. For a long time, one of the strongest runes was conqueror.
Basically, conqueror gives you a stack (a special point, let's say) for each hit you get on an enemy champion. Get enough, and the rune 'procs', or delivers its effect. In conqueror's case, it's healing and significant damage. Conqueror has gotten toned down (nerfed) a few times because of its overwhelming power on some champions, but the recent change is a real blow. Now, instead of having to get to 10 stacks, one must get to 12 because it procs. Tough luck, Darius.
A nice thought by RIOT to keep us entertained (and playing) during this epidemic are the Stay Safe Together Missions. It's just five missions that give some pretty basic (but nice) prizes for achieving them (plus one that you get for completing the five missions).
The champ nerfs and buffs this patch are pretty significant. Cassiopeia, long a tyrant of the mid lane, is finally getting a small nerf of 34 magic resist to 32. Aphelios and Ornn are similarly receiving the nerf treatment.
Really excited about the new buffs, especially Nunu and Lucian.
