Effects, Emotes and Executions are all set in the Heroes Customization menu. Non-default effects, emotes and executions can be purchased for varying amounts of Steel, and if you have the season pass or deluxe pack or enough points in Ubisoft club you will only need to buy an execution and an emote since the sunbeam effect is available already.
Without the pass or deluxe pack or buying the sunbeam effect from the Ubisoft Club, you'll need at minimum 13,000 Steel to buy the 5,000 execution, 3,000 emote and 3,000 effect.
