Runes

Runes are special boosters that spawn on the game map. They come in two categories. Bounty Runes can be picked up for extra gold and experience, while Power-up Runes grant heroes a variety of buffs and effects for a short period of time.

Spawning

 * Bounty Runes spawn at 0:00 on the game clock, and every two minutes after that.
 * Power-up Runes spawn at 2:00 on the game clock, and every two minutes after that.
 * Bounty Runes spawn at four locations on the map, two on the side, and two on the  side.
 * Power-up Runes spawn randomly at one of two locations in the river.
 * Only one Power-up Rune will spawn at a time.
 * The same Power-up Rune will not spawn twice in a row.
 * Unused runes will be replaced by a new rune at the next spawn time.

Bottling

 * Runes can be stored inside a.
 * Heroes with a Bottle in their inventory will automatically store the rune inside the Bottle when they pick it up.
 * A stored rune can be used later by activating the Bottle.
 * Using a stored Power-up Rune refills the Bottle to full, with 3/3 charges.
 * Using a stored Bounty Rune refills 2 Bottle charges.
 * Bounty Runes cannot be stored in a Bottle that has full charges. Instead, it will be automatically consumed upon pickup.
 * Runes can be stored in the Bottle for up to two minutes, after which they are automatically activated.
 * Bottles containing runes cannot be dropped or shared.
 * When the Bottle is filled with a rune, picking up a second rune will consume/activate the new rune right away, not replace the existing rune in the Bottle.

Other

 * Power-up Runes are only visible on the minimap in spectator mode.
 * Bounty Runes are always visible.
 * Runes can be destroyed by normal attacks, using a forced attack command.
 * Since runes do not count as units, destroying or denying a rune neither counts as a last hit, nor interacts with any abilities in the game.
 * Runes have selection boxes with higher priority over units, meaning that if a unit is standing over a rune, the mouse cursor highlights and selects the rune first.
 * This only applies to actions that can target runes, such as moving or attacking. Actions that cannot target runes will still target the unit first.
 * Currently, the only ability that can directly target runes is Tiny's.
