Game mode: The harrowing
Map type: Twisted tree line Changes to the map: jungle and terrain are in the dark blue spectrum with light blue patches around it. The mist is in the blue green like in the Pledge video. Special affects: much like doom bots but you fight the champion of the black mist. They get upgrades to their abilities and instead of fighting the spider you fight the ruined king for the buff. Abilities: (just a few ideas) Kalista can throw three spears in rapid succession instead of one and the rend pulls all spears out and toward her doing damage to all that they pass through. Yoric's wall saps the health from you as you are in is and he can summon 7 minions instead of four. Mordikieser gives the W to all minions and champions around. Hecerams ult summons the shadow riders to go forward at a world wide range fearing everything in their path. Evylynns hate spikes shoot to the nearest three people and her ult covers a range then explodes again giving her more of a shield. Molokai gives his ult to all friendly champions around him and his ground punch goes longer. Karthus's wall of pain does a DOT and his Q is a larger area critting one any champion he hits regardless of minions in it as well. The ruined king: we don't know that much of him besides from Mordikiesers back story so this game mode could give riot a chance to more define him as a character. Naturally BORK would be disabled for the map because its his blade. he will do % max health with each attack and will have some sort of AOE damaging aura. The alters: as I said BORK will be disabled but the alters would give you the BORK affects if you had both of them. At least one of the shadow isle champions will try to get the alters for their team. Other ideas: The minnions would be like Zyra's Harrowing skin when she grows the ranged attackers. The jungle monsters would be harrowing themed and there would only be three per game so the random selector would be nice to make every game different.
