Buff Analysis
Now that we have gone over an overall summary of what their buffs will entail, here is an overall analysis of how their buffs will affect the way Sparkle and Black Swan will play in the future:
– Sparkle: Sparkle has received a massive overhaul to help her support ability further when used in a Skill Point centric team, with her Skill now no longer requiring Skill Point usage when allies have consumed 3 Skill Points per turn and her buff duration lasting 2 turns instead of 1 now.
Additionally, with the effect to recover even more Skill Point and store any excess Skill Point to be used by allies later after using her Ultimate, players won’t need to micro manage her Ultimate usage and can just use it whenever to buff the damage of the team. Additionally, Sparkle will now be able to use her abilities and ultimate much faster thanks to her new speed and energy buffs.
– Black Swan: Black Swan’s improvement is overall quite easy to understand: with the new buffs, all of Black Swan attacks will now inflict 5 stacks of Arcana on enemies and reduce their defenses. Additionally, her stacking and reset conditions are changed immensely to allow Black Swan to maintain her Arcana stacks on enemies much more efficiently by simply halving her Arcana stacks on enemies’ turns rather than resetting them.
These overall buffs make Black Swan into a more reliable debuffer for DoT team and help improve the team’s damage uptime overall.
