UPDATE `spell_proc_event` SET `ppmRate` = 2 WHERE `entry` = 51528;
UPDATE `spell_proc_event` SET `ppmRate` = 4 WHERE `entry` = 51529;
UPDATE `spell_proc_event` SET `ppmRate` = 6 WHERE `entry` = 51530;
UPDATE `spell_proc_event` SET `ppmRate` = 8 WHERE `entry` = 51531;
UPDATE `spell_proc_event` SET `ppmRate` = 10 WHERE `entry` = 51532;
