Another titbit from the latest Countercharge podcast (ep 518)…
KoM are getting two new units;
“Beast Cavalry”, with upgrades to give them either flying or better melee stats. I don’t think they specified whether these will be “cavalry” or “monstrous cavalry”, so don’t go basing any new units yet!
A  “Monarch” Hero on a Dragon. with multiple upgrades. They mentioned the option to give it wings or keep it grounded, but there’ll be other options to give it various special rules.
The idea was apparently to give KoM more fantasy elements, whilst maintaining their “blank slate” feel to allow players to customise units how they want.
They also clarified Rampage and Slayer a little. I don’t remember exactly what they said (sorry!), but they did pretty much confirm what we said earlier about the rules - extra attacks vs monster stuff (slayer) or infantry stuff (rampage). Most (all?) Titans will be getting one of these two rules.
