Valve have learnt their lesson from Diretide: don’t deny the Dota 2 community their holiday celebrations. That means that Frostivus is back. The holiday event is traditionally quite lovely. Last year’s Frostivus started normally before being taken over by The Greeviling, an update and game mode in which players can use their Greevil a secondary hero. At this point, I’d normally make a crack about how I don’t understand any of this and don’t care, but truthfully, I do understand it. It’s just easier to be flippant than explain all the context. Instead, this time, I’ll take door number three and link to the Dota 2 wiki page about the Greeviling event.
