the new tooltip of cataclysm on wowhead reads
Cataclysm: Kanrethad channels cataclysmic power, immolating all enemies within 100 yards every 1 sec. After 6 sec, all enemies within 100 yards take 1000000 Fire damage and are knocked away and stunned for 10 sec. Once started, the channeling of Cataclysm cannot be stopped by any mortal means.
is this a poke at Xelnath ?
