The Charm of Time is available from the in-game shop, and costs 250 beads. Beads are the earnable currency, and they seem to come very quickly in Treetopia. This charm will reduce the collect time on a building by 10%. That's not much, but we're sure bigger and better charms will be coming. The other new charm can only be obtained as a free gift. The Charm of Riches is a level 1 gift that gives you double resources for every villager who visits that building.
To apply charms, simply use them from your storage and click on any building in your village to apply the charm to it. This is a nice addition to Treetopia, but we're sure these charms won't remain cheap and free as they start releasing more effective ones.
