Two months ago, a new Runes system for League of Legends was introduced and it will be implemented during the pre-season in November. A new component in the Runes system, the Keystone Runes is one of the strongest element in it, and two new but familiar Keystone Runes was revealed by Riot in the League of Legends Runes Corner.
The two new Keystone Runes are Stormlord's Mandate and Spellslinger's Surge. Sounds familiar? That's because it is inspired from the current Keystone Masteries, Thunderlord's Decree and Stormraider's Surge.
"On top of building new content, we are also looking for opportunities to bring back some of the keystones you love and see if we can make them even better," RiotWrekz stated in his post.
Hitting a champion with 3 unique attacks or abilities within 2 seconds deals bonus magic damage.
Damage: 40-220(+25% Bonus AD)(+20% Ability Power)
Cooldown: 50 seconds
Stormlord's Mandate is very similar to Thunderlord's Decree, but with higher damage output and increased cooldown in order to focus it more on all-ins, and it is also now harder to proc. As stated in the description above, landing three unique attacks on your enemies is needed to proc the effect. If you are wondering what do three unique attacks mean, RiotWrekz also gave a detailed example on how would Stormlord's Mandate proc.
"Each spell, ability, or individual attack counts once towards triggering this. Sounds pretty simple. Let’s look at some examples. Start with an easy one: Mystic Shot. You fire it and it hits your opponent. That’s one. Attacks work the same way. The biggest change is how it works with damage over time effects. For example, Miss Fortune’s Make it Rain. When you cast that on an enemy it deals damage rapidly for 2 seconds but it still only counts as one spell. With the “unique” flag Stormlord’s Mandate won’t be instantly triggered by Make it Rain the way Thunderlord’s was. If you would like to actually play and experiment with the unique keyword, check out Maokai’s passive for a better idea. Overall, the unique keyword allows these keystones to bind more to all-ins and intense fighting rather than specific champion abilities," RiotWrekz posted.
Hitting a champion with 3 unique attacks or abilities within 2 seconds grants 30%-60% movement speed for 3 seconds. Additionally, Melee champions gain 75% slow resistance while active.
Cooldown: 15 seconds
Besides the movement speed buff and the slow resistance, everything about Spellslinger's Surge is totally different from Stormraider's Surge, especially the requirement to proc it. Instead of dealing 30% of a champion's maximum health to proc it like Stormraider's Surge, the Spellslinger Surge rune requires you to do the same thing as Stormlord's Mandate, which is hitting a champion with 3 unique attacks within 2 seconds.
"Spellslinger’s Surge is a modification we’ve been testing to the Stormraider’s Surge keystone mastery. Many players find the movement speed granted by Stormraider’s exciting. However, it was hard to predict when you would do enough damage to trigger it. We saw an opportunity to use the “unique” keyword to provide that same effect in a more understandable way while also creating a parallel rune to Stormlord’s. Spellslinger’s Surge lets you get a reliable burst of movement speed in the middle of your all-in, allowing you to decide whether to disengage or continue chasing down that enemy," RiotWrekz mentioned.
