Memes aside, SAA MOD is a strong HG and offers a lot to all players. On top of her enhanced tiles and Skill 1, her new Skill 2,
Duel Survivor, periodically increases the Rate of Fire and Accuracy of all allies
every 4 seconds (up to 3 stacks). Combined with her already decent damage boosting capabilities, what you have now is an incredible HG who buffs team DPS while also synergizing with dolls that proc off of receiving buffs like M500 MOD. As a fun fact, you can even reduce the interval between her Skill 2 boosts with RF cooldown reduction tiles..
The versatility of what SAA MOD offers makes her a worthwhile Neural Upgrade for most commanders. As she is a support through and through, her MOD3 Special Equipment is not particularly beneficial, so
it is recommended to upgrade her to MOD2 until you can complete her SPEQ-Set.
SAA now has two SPEQ-Sets available as well. The first one increases her maximum amount of Skill 2 stacks from 3 to 5, and gives damage reduction per stack. The second is a bit odd but very strong, granting her damage immunity and a staggering 11x damage boost for 10 seconds when she only has one link left, which can still kick in even if she starts the battle with 1 link. Overall, the first bonus is decent but optional, but that damage immunity is extremely good.
