Hordes warbeasts do not have an arc node equivalent.
Usually you will look for models with the Channeler rule, but there are a few other effects that allow for spells to be channeled such as pHexeris’ spell, eHexeris’ bond, or pVayl’s ranged attack. Hordes factions do have the market cornered on channeling solos though, with circle’s gallows groves and everblight’s spell martyrs.

So it’s best if i get the ‘forces of’ book to find out which models have channeling.

Thank you, it wasn’t very clear in the rulebook.

Channelling in Hordes is much more model specific….HOWEVER…a Warlock can, in their activation, pay fury off themselves to use a beast’s animus FROM the beast (So Madrak 10″ from an Impaler pays to have it give it’s animus to a Bomber 16″ from Madrak but only 4″ from the Impaler). This is channeling how it happens most often in Hordes. Certain other models can channel (Spell Martyrs, Gallows Grove, certain bonded beasts etc.) as Dais says but this is not the most common method in Hordes.

As a small note: the Forces of Hordes books no longer contain the full complement of models for each faction as Hordes: Domination has added several new models for each faction on top of them as well as the new rules for Battle Engines.

For 2 points the Wilder’s not bad as opportunities go to do things like extend your control range. For instance…if you know a charge will take a beast out of control range then simply running the Wilder out can give you the extra few inches you need to get there and boost. The ability to clear off Fury can be handy too…..charge a beast out, load it up, condition it to remove all the fury…..Suddenly your Warlock can transfer to it more easilly and a second beast can go all out the same turn with no potential of a frenzy next turn.

Well, if a book proves to be too expensive, you could always go for faction decks. They only cost a fraction and still have all the rules, although to be honest I have no idea if the new domination units are included

Also of note: Faction decks contain cards only up to (But not including) Warmachine Prime/Hordes Primal Mk2. So they would be missing the new beast from each force in Prime, the new units/beasts/UAs from the faction books AND everything from Hordes: Domination.

I ment no offence. I’m like you, I love a nice bit of background

My friend got his deck to upgrade from MKI to MKII, he got a card for everythong in the forces book, but like you said, nothing from the expantions
