Correct ^
the description (link) says
“Each spell has a 25% chance per rank to reset the other spell’s cooldown.”
As it’s not specifically says shatter, is it outdated?
That word other means ’ if casting meteor it has a chance to reset cool down of the other 1 skill’wich is shatter, and vise versa.
OK, clearer like that thanks 
When your Meteor spell hits the ground, it has a 25% chance per rank to
cast Taunt. When you cast Shatter, it has a 25% chance per rank to cast
Fear. Each spell has a 25% chance per rank to reset the other spell’s
cooldown.
Yeah, the wiki is currently a “little bit” outdated.
