Very few units in FFBE have passives or active modifier buffs affecting healing skills. The vast majority that do are tied to damage skills, and I honestly can't tell if all of these are actually intentional (particularly in the old SBB cases of Ashe and Summer Folka & Citra). This is mostly a dumb quirk and old news, but it means that NV remake Aerith can get away with the hot bullshit of a full party heal in a full damage turn. I thought it might be handy or at least interesting to list affected skills.

NV Aerith (BS) イノセンスフォース: 1800 HP, 8x -> 1800 HP, 23x (active buff)

NV Aerith (BS) テンペスト: 1500 HP, 11x -> 1500 HP, 16x -> 1500 HP, 31x (passive and active buffs)

Ashe Heaven's Fury: 1200 HP, 3.4x -> 1200 HP, 21.4x (SBB)

Princess Ashe 聖光爆裂斬・風/炎/雷: 2400 HP, 3.4x -> 2400 HP, 25.9x (active buff)

Summer Folka & Citra High Tide Spirit: 1000 HP, 3.4x -> 1000 HP, 13.4x (SBB)

MachinaV2 フィアーブレイド: 6000 HP, 0.3x -> 6000 HP, 20.3x (active buff, self only)

RemV2 全癒の祈り: 1000 HP, 3.4x -> 1000 HP, 7.4x (clearly intended)

CG Citra Holy Mind: 1000 HP, 3.4x -> 1000 HP 5.4x -> 1000 HP, 7.4x (per copy of Aerith STMR)

Global only:

Doctor Aiden Operate - Steralization & Operate - Antibodies Boost: 1000 HP, 3x -> 1000 HP, 8x & 2000 HP, 8x -> 2000 HP, 13x (active buff, clearly intended)

Likely missing some, do comment if you find any.
