Well it is a usual problem that all tanks have. I have a lvl 53 fighter and I party with a lvl 57 cleric and he doesn't steal aggro. If you are above lvl 43 you can have devastate* you use that then mock*. That will keep aggro on you. Also if you have a low lvl cleric you need to take them to an area that they can deal with such as if they are lvl 10 or below take them to Goblin Camp not Collapsed Prison or Vine Tomb. Moonlight tomb would work some what but in Moonlight tomb you aggro until lvl 45 on all classes. Goblin camp can be the same but if you do not have any quests for there then adding a lower lvl can actually boost your exp rather than take from it.

Also partying with members that hit more often and harder than you can be a problem also. Especially if they use scrolls I.E. Vitality, Aim, Evasion, Mentality, Shield, and Magic Defense. I have a problem keeping aggro when I am with a lvl 50+ archer do to the dots or skills they can have high dexerity and damage. But using a combo of confuse (stun)/Devastate (AoE** stun) and mock/snearing kick can help a great deal.

BTW Mock is more effective than Snearing kick. Snearing kick is a lower lvl mock. You need to get Mock the AoE** attack.

Hope this helps some. ^_^
