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 1/512. However, its drop rate of the obsidian cape is four times more likely compared to other monsters, at 1/128 rather than 1/512.
