Here are patch notes for Summerset:
Racial
Argonian
Argonian Resistance: Updated this ability’s tooltip to indicate it grants immunity to the Poisoned and Diseased status effects.
Dark Elf
Resist Flame: Updated this ability’s tooltip to indicate it grants immunity to the Burning status effect.
Nord
Resist Frost: Updated this ability’s tooltip to indicate it grants immunity to the Chill status effect.
Wood Elf
Resist Affliction: Updated this ability’s tooltip to indicate it grants immunity to the Poisoned and Diseased status effects.
So in PvE for example are Bosmer and Argonians immune to the SO poison over time or immune to the VMA poison buds in stage 7??
Also in PvP are they immune to the poison dots of DK poison talons or poison injection??
Seems too good, but maybe I misinterpreted that.
