Increase Buff Duration Champion List | Raid Shadow Legends

Raid Shadow Legends Increase Buff Duration Skill allows a champion to extend the buff duration on a champion, which means increasing all buffs duration on their allies. This allows the buff to provide their benefits to the allied Champion longer to increase their survivability and efficiency in battle. Unkillable, Block Damage, Revive on Death are not affected by Increase Buff Duration effects.

    Oella should be added to the list (Sylvan Watchers Legendary, 3-turn cooldown)

  2. YoMammasBoy

    Also, Quargan the Crowned’s ability is single target at random.

  3. YoMommasBoy

    The new champion Duedan, from the Sylvan Watchers, has this skill as an AoE

  4. Redtailed

    Epic Support champion “Anchorite” has the increase buff on his A2

  6. Jenifer Adams

    Quargan isn’t AOE, it’s random buff on single target. Ty for your hard work your site is excellent

    @Lozza, @CasualNoob, @bakayoutube: Hellborn Sprite has been added to the Increase Buff Duration (AoE) champion list!

  8. Pir

    @timbos — no, anything to do with buffs on one’s own allies doesn’t require ACC.

  10. CasualNoob

    Need to add Hellborn (Demonspawn rare) to this list.

  11. Lozza

    Hellborne Sprite?

  12. Thavious

    Agust, read Valeries engergizing presence, It says increases the durations of buffs on all allies by 1 turn. It’s a 4 turn cooldown (3 when booked).

  13. Ágúst

    Valerie does not extend buffs in Raid anymore.

  14. Paendamonium

    Godseeker Aniri has increase buff duration on her A2, though it combines with several other effects.

  15. timbos

    does his extending skill requires accuracy

  16. overborn

    Seems like unkill cannot be extended
