Runes

Runes are special items you can obtain that vanish when picked up, and give you a powerful effect for a short time.

Spawning
Runes will spawn every two minutes at one of two locations on the map, if there isn't a rune already on the map. The last rune must be taken in order for a new one to spawn. Runes will spawn in the river at two locations, either between the top and middle lanes, or between the middle and bottom lanes.

Bottling Runes
You can use an Empty Bottle to store runes. Runes that are stored in an empty bottle will be automatically used after two minutes. A hero that stores a rune can use the stored rune by using the bottle. Using a bottled rune will refill the hero's bottle to 3/3 Full. Bottles cannot be dropped if they have a rune in them.
