    I took Aothar for poison and Flesh-Tearer for increasing debuff. And he ist on ascend level 3, so his A3 is in superior level.

    @Smartboz: What are the champions did you use to test this out?

    I tested it myself right now: Poison is not affected as well by increase debuff duration. Tested it multiple times, and there was no notice, that the opponent resisted.

    @Blue Overnight: Based from what I heard from the moderator on the RAID Shadow Legends Official Discord, they mentioned that Sniper does not affect Debuff Extender. Some players who have Septimus (Legendary Champion) tested that he does not extend the debuff with Sniper but through Warmaster (additional attack) from Offense Tier 6 Mastery.

    Can you confirm if the sniper masterie works on Debuff extentenders?

    @yivgeni: Yes, Increase Debuff Duration works on all debuffs except for Crowd Control types such as Stun, Provoke, Sleep and Freeze.

    I can confirm that Master Hexer works on Septimus, increasing debuffs for 2 turn. However, he has a passive to grant this effect, while Warlord and Vizier have such effect built in their skills.

    Does anyone know if sniper or master hexer affect this ability?

    @Mick: It can be resisted if your champion’s accuracy is lower than the enemy champion’s resist.

  13. Mick

    As it is not applying debuff, is it countered by resist? Thanks
