Hearthstone Hallow’s End Event coming on October 1st
Hallow’s End is a Hearthstone seasonal event that is coming on October 1st.
During the event, a new Arena Dual-mode is available. When entering an Arena run, players first choose a Hero class (Only classic Heroes can be used, and they are using costumes) and then a Hero Power from other classes and can draft cards from both classes.
Heroes use alternative, festive Greetings emotes
In the past, Bundles appeared, special Tavern Brawl were playable, and we even were able to play Wild Cards in Standard.
Disclaimer: Informations are based on the Event the last three times, there is a small chance that the Event will feature something else.
How to get the Notification?
