Is the beast runeword worth it for a Necrcomancer

[Wyrm]

Does anyone have experience using a Best runeword with a skellemancer?

Getting somewhat back on track with the topic... I don't have any experience with the Beast runeword on a skelmancer, but I do have some when working with Fanat. The increase in damage is going to be fairly negligable, though it will be coupled with a nice AR boost and a decent ias boost (I have no idea where skeleton breakpoints are). With the added AR from fanat, you should be able to not need a BA merc for it's AR and could get yourself a Might merc (or Thorns if you want to live safely, but if you're making a Beast, then a Bramble might not be *too* hard to get) and that will increase your killing speed significantly (Skels on their own without an AR aura tend to not hit that much).
