The amiibo Buff refers to the automatic stat increase Figure Players receive in both Super Smash Bros. 4 and Super Smash Bros. Ultimate. It has been a point of controversy among casual trainers, who perceive these enhancements as overpowered and unfair to human players.
In Super Smash Bros. 4, FPs receive an automatic 1.5x boost to their attack and defense stats regardless of whether or not they were given equipment. Lowering the FP’s attack and defense stats to -50 via equipment pieces will nullify the amiibo buff. That being said, Smash 4’s AI is notorious for its defensiveness and tends to falter against aggressive opponents. Reducing the FP’s stat total is not recommended.
The amiibo buff has been noticeably weakened in Super Smash Bros. Ultimate. FPs only receive a 1.3x boost to their attack and defense stats, once again regardless of (and in addition to, if applicable) their Spirit setup. Unlike in the previous title, giving an FP negative stat points only negligibly reduces its attack and defense; this means there is no way to nullify the amiibo buff in this game.
