: Earth and Water. Dark Release is used to absorb and redirect chakra and energy in general. This makes it so that while it can absorb the chakra in Earth and Water techniques, it will have a difficult time absorbing the Earth itself or the Water produced by techniques since it doesn't work exactly like a Fuuinjutsu technique. Earth suffers double strength towards the absorbing ability of Dark Release (meaning that only an S-Rank Dark release can absorb a B-Rank Earth technique)
: Raw chakra, Fire, Lightning, Wind and other forms of raw energy like Storm, Dust, Scorch or even raw Sage Jutsu. Raw chakra absorption and redirection is the core of Dark Release, making it gain double strength towards it (B-Rank Dark overcomes S-Rank Raw Chakra).
Weak to: Earth and Water. Both elements have substance and density to defend from raw forms of energy like those produced by dark release after the absorption of a technique. Other solid elemental forms may serve the same purpose, such as Solid Ice, Steel, Wood or Lava
: Wind and Fire. Both elements lack the substance and strength needed to actually overcome or even deal with the raw form of energy produced from dark release after absorbing a technique. Other intangible or less tangible elements such Snow (basically, snow based ice techniques), Sand, Rain, Steam, Boil, etc may also be susceptible of being overcome by the raw energy of Dark Release.
