In the latest patch I updated the modstrings.txt, I also updated it in my dropbox, so the old link has the new file. Here's the line that changed:

xtagMasteryDescription09={^B}{&B}Path of Poseidon{^W}{&S}{^n} Walking this Path is to pursue becoming the Avatar of Poseidon. Powers over oceans and storms, the blessings of horses, and many skills relating to Poseidon's children are gifted to a devoted follower. {^n}{^n}{&i}Religious Warriors, Cultists, Priests, Fanatics, Sea Druids and Wizards are just a few of those who swear fealty to Poseidon. {&S}{^n}{^n}{&B}{^B}Strengths:{&S}{^W} {^n} -Very strong Pet {^n} -Incredible AoE {^n} -Strong Weapon Enchantment {^n} -Natural Resistances {^n} -Lower Strength Requirement for all gear {^n}{^n}{&B}{^B}Weaknesses:{&S}{^W}{^n} -Vitality Damage Vulnerability{^n} -Skills are not versatile{^n} -High Mana cost for skills with small Mana pool {^n}{^n}{&B}{^B}Path Level{&S}{^W}{^n} -Fire Vulnerability that gradually changes into Fire Resistance{^n} -Bonus Health and Intelligence {^n} -Lightning, Cold, and Stun resistance{^n}

EDIT: I also changed this line:

tagSkillDescription1111=Create a burst of energy that tears through all nearby foes. {^S}Cooldown:1.0

(Cooldown was 3.0)
