Orc Mages are definitely a Mage/Tank hybrid, and probably some of the most dangerous classes in the game, especially the Overlord. The curses that class have will ruin anyones playtime. :p
Although its a vast difference from a DA. The Orc Mystic is really hard to level up early game, but eventually they become really REALLY powerful.
On a more evil note:
There are NEVER enough Dark Elves! WE WILL RULE THE WORLD!!! HAHAHAHAHAAAAAAA!!!!!
The main thing, however, to remember about the Overlord is that to be effective they need a solid clan. (Not for curses obviously but for regular gameplay and to take advantage of their purpose.)
That or Staff. They can really wield anything aside from bows (just because in C5 they're making a penalty for that), so it depends on you playstyle. A spellcaster Overlord is going to use a staff, whereas a Tank Overlord is going to have a shield and blunt. Although I would suggest sticking with mystic stuff just because the Overlord is a spellcaster class more than the Warlord.
The Warlord on the other hand is all about going in a beating the snot out of stuff. Less efficiant than the Overlord but still gets the job done.
The blunt is used because you will need it to use your PvP/PvE skills (Stun/Hammer Crush). A sword gets more crits but your accuracy sucks as a mystic. Your weapon mastery is generic so it applies to any weapon (right now anyways), but blunt is most accurate.
Your method of hunting is bash, bash, bash, and then when you get low on HPs, use Life Drain (Steal Essence past lvl 40). Their drain is quite powerful and will restore a lot of HPs, if you combine with Blessed Spiritshots. Your armor choice is up to you. I prefer Heavy.
PS: the correct quote from Pinhead is "Your suffering will be legendary, even in hell!"
overlord is one of the hardest to lvl yet vastly over powered classes.
in the olympiad Over lord wins just about every time, it's hard to beat a class that has soul guard and life drain that restores so much HP it's imposseible to defeat them.
OL; can do AoE, and is great in sieges. can solo with a vast array of weapons anything from staffs to swords to blunts even duels or two handed.
