When Game of Thrones finally ended and the Frost Kings army were put to the sword Gravechill and her sister Frozen Banshee were out of work, luckily Raid Shadow Legends were hiring! Gravechill Killer is an Undead Hordes Magic affinity rare champion introduced when Raid: Shadow Legends first had a battle pass. Alone she has a strong skillset offering both poisons and decrease defence debuffs, however adds far more benefit to a team when paired with Frozen Banshee. Frozen Banshee ensures Gravechill can always place the strong version of Decrease Defence and place additional poison debuffs. She is strongest in Clan Boss and Dragon and can comfortably play through the mid game in those teams.
Overall a good rare to help your account grow but will drop off when you hit mid game.
