Bleed immune also immune to Elektra's armor break
While fighting Nebula just now (Rocket's scrapyard medium quest, hard path), I used Elektra's special 1 ability, which has a chance to cause bleed in normal opponents and armor break if the opponent is bleed immune. Nebula is bleed immune, so it should have triggered armor break or nothing, but instead I got two "immune" triggers. Nebula is not immune to armor break.
