—Trait description
Abjurer Supporter, colloquially known as Buffer Supporter, is a branch of the Supporterclass in Arknights.
Abjurer Supporters are similar to Hexer Supporters, but will heal friendly units instead of attacking enemies for 75% of their ATK when their skills are active, which augments friendly defensive capabilities by applying the Sanctuary buff on friendlies, usually when they are at low HP.
Trait improved: Deals Arts damage; When skill is active, attacks instead restore the HP of allies (heal amount is equal to 100% of ATK).
Strategies
Abjurer Supporter's healing are less optimal compared to Medics, although their defensive buffs offset this by allowing friendly units to survive better. It's also advised to provide them with an ATK buff to boost their healing capabilities.
Modules
The BLS-X Module solves the Abjurers' lackluster healing by no longer reducing the amount, allowing their healing ability to be almost comparable with Medics.
