Weapon choice for Pure Cleric

[Target-Practice100]

When I want to kill undead with my cleric I use Turn Undead, after all thats why clerics have it. Maybe better to find a crafter to make you a nice higher level Sacred item to increase your turning power. And get the Token of the Faithful trinket to increase your number of turns by +2, and also boosts your turning ability. There is also a couple of cleric spells you should have, or soon will that will either increase your turning ability, or will kill undead. There are also some bracers that can stun non-intellegent undead for up to 30 seconds, which is great for undead crowd control. If you want the names of any of these let me know and I will check on my cleric.
And of course, you have your Radiant Servant Burst, which when used with Empower Healing, can hit undead for well over 100 HP, and like Turn Undead, its an area of effect weapon. The fact that it also heals your party at the same time just makes it even better.
Basically, if you are a cleric, and have a decent Charisma, you don't need to hit undead to kill them, you are a born undead killer, as long as you have some decent Sacred gear for it that is.

You could use a greatsword and ask in general chat for a warforged pally/cleric to make you champion of the LoB. Gives proficiency and lasts till you log or die.
Since you considered dual boxing you can take it at lvl 1 and it would be way less hassle than master's touch.
