Time Chargers will make it easier for you to play the Story Events. Time Charger Shards Level 1 are produced by the Grandfather Clock in Ignatius Boulton and by the Tower in Lindsay’s New York Story. They can be merged up to Level 4 Time Charger Shard and these Shards can be merged even further to produce a Small Time Charger Level 1 which has charge for two hours. You can also create larger Time Chargers that can be activated for an even longer period of time.
Time Chargers can be activated by double-tapping on them. Once activated, they double the Recharge Speed of producers/spawners in the 8 squares around where they are placed on the Event Board.
