With Season 1 of The First Descendant on the horizon, players can anticipate the addition of new mechanics, balance improvements, new Descendants, and a couple of new Ultimate weapons. These ultimate weapons have highly useful abilities to increase DPS, so players will likely want to seek them out as soon as possible. The first ultimate weapon, Excava, seems to be viable for any build, but the second seems purposely built with Hailey in mind.
