Converting Farland Magic Items

Let's use this thread to convert Farland 3.5 magic items to 4E. Converted items should retain the flavor of the original, but no attempt need be made to match exactly.

Here's an attempt at the Crossbow of Wawmar

Original 3.5 item

Crossbow of Wawmar

Crafted under the hammers of the most expert metalsmiths in the world, the dwarves of Wawmar, this steel +3 heavy crossbow cannot be broken in battle or under normal use, although it is not indestructible (it can be destroyed in a normal forge). If the total number rolled to hit is 4 above the target's AC, then the opponent must save vs. will at DC 15 or be held as per a hold person spell cast by a 12th level caster. This power functions three times per day.

Moderate enchantment; CL 10th; Craft Magic Arms and Armor, hold person; Price 32,000* (Dwarven item).

4E corresponding item

Power (Daily): Free Action. Use this power when you hit with this weapon. The target is immobilized until the end of your next turn.

I know this one is pretty straight forward. Any comments on it?

No save for the held immobile? As a level 2 item, that rocks.

I'd make it a minor action to use as well. Can/should it be limited to basic attacks only?

My thoughts:

I based it off a level 2 item, the Resounding weapon, that dazes until the end of the turn. I think dazing is potentially more powerful. It is a daily power. I think making it have a save makes it potentially more powerful-- it could last longer. That was my reasoning. See any flaws?

I agree. Immobilized really isn't all that much of a penalty. You can still attack, still take minor actions - you just can't move.

This looks perfectly fine. Until EoT is the minimum for save effects anyway.

Except this is Until End of Next Turn, but yeah, I think the weapon is fine.

End of MY next turn is functionally equivalent to end of their next turn for immobilize, unless they have a reaction like elven archers do.

And so it is, because they lose the same amount of turns-- 1. Good point. So it is clear that it is weaker than allowing a save.
