When speaking to Ealcil for the first time in the quest The Tempest Unleashed, his dialogue text reads "the of a Storm Totem energies".
"of" in this phrase is incorrect and should be removed.
Another text bug in the same quest chain:
One quest objective is given as "Use Lodestone to Drain Storm Totems".
While the gratuitous capitalisation of nouns is questionable but somewhat defensible, the capitalisation of "Drain" is incorrect and it should be "drain".
