Mordru's sorcerous powers are amongst the most formidable in the DC universe. He is capable of flight, control over matter at a molecular level, generation of magical energy in the form of bolts or shields, and the formation of solid objects. He can magically heal fatal wounds sustained by himself or those of others, and even regrow limbs out of "cthonic energy." When Alan Scott slashed Mordru's abdomen open with an energy sword, the sorcerer was able to heal the injury in seconds before ripping the Starheart from Alan's body. During his attack on the Justice Society in New York, he was able to take multiple blows from Power Girl without serious damage, and was able to withstand a joint attack by the JSA and the Freedom Fighters. He has also demonstrated superhuman strength sufficient to lift objects weighing several tons with relative ease.
