different type of bones list?

Basically I am going to say the biggest reason I don't take them is they don't count for free points in bones of orboros in addition to competing with woldwyrds.

Wyrds are 1 point less, have purgation, some other cool abilities, are overall more durable and fire at similar output due to boosts.

Woldstalkers really need a caster that can simultaneously increase accuracy and pow, Tanith seems like a really great options for that, as with scytouch and her ability to swing def by up to 7 with megs, her gun, and affliction, she makes them basically rat 13 pow 14 guns which is kinda awesome.

They hit pretty hard once you get concentrated fire going, the issue is, if you miss one single shot the entire units output goes down significantly. If you can land every shot, they can cap out at Pow 19 with a damage buff which is pretty nice.

Having said all that, give them a shot, tanith certainly does a lot for them, and they are certainly good enough to test on their own. I ran them a bit with Mohsar before themes and wyrds got buffed, and had mixed success. Most of the time one or 2 of the shots would miss, making me a sad panda when it came to cracking a hard target. But if they all hit, it got pretty legit. Also, mohsar let them threat 21 inches with mirage and zephyr.
