The TzHaar-Mej are both the leaders of the TzHaar people and powerful mages. They fight with both melee and magic using their staves. When attacked within 6 squares of other higher level TzHaar (Ket and Xil), the mage will cry out "kot kl, zek e JalYt!" which roughly translates to "save me attack the human." This will cause the nearby TzHaar to aid the TzHaar-Mej in combat.
Unlike other TzHaar monsters, the drop rate of TzHaar-Mej dropping the Toktz-mej-tal is significantly lower than the rate of other TzHaar weapons, being 1/4000 whilst the other TzHaar drop weapons at a rate of 1/128.
