Lone Druid

Sylla the Lone Druid is an adaptable and versatile ranged or melee agility Hero, who summons a Spirit Bear, which has its own set of abilities and can equip items, as his ally. With the help of his Spirit Bear, he can carry, jungle, and push lanes effectively. Because of these, technically speaking, the Spirit Bear and Lone Druid himself, are two available heroes at once. The Lone Druid himself is mostly played as the aura giver, while the Spirit Bear is played as the main damage dealer and tank. When he activates his abilities, it will not only buff him but the Spirit Bear as well. Lone Druid is versatile as he can change from a fast ranged warrior to a tough and mighty melee bear himself. Together, they can push the lanes effectively, farm Neutrals in a clinch, and can take down Roshan by themselves if equipped with the right items. Due to the Spirit Bear, Lone Druid can have up to 12 items making him extremely formidable as he scales into the late game.

Tips

 * Due to the bear's very high health, he can be used to tank neutrals and jungle early game, or provide good lane control with harassment and last hitting, with very little risk of dying.
 * With two or more levels of Synergy, Rabid can be continually used, since the cooldown does not exceed the duration.
 * The bear benefits greatly from attack speed items as they make entangle more reliable.
 * Items that provide some kind of aura are a good choice as they benefit both Lone Druid and his Spirit Bear.
 * Take note that due to the fact that the Spirit Bear's stats are static if the game goes too long he falls short against an enemy hard carry. Lone Druid is usually picked in push heavy line ups to be able to push into the enemy base using his bear's bonus damage against buildings long before the enemy carry has had time to farm. If this fails you should begin planning on itemizing Lone Druid himself.
 * In a team fight if your bear is about to die you can make Lone Druid the main damage dealer by transferring the bear's items to your main hero.

Various mechanics
Items cooldowns
 * Sylla and Spirit Bear cannot pass items to each other to avoid or bypass an activatable item's cooldown.
 * In other words, once an item is activated, the cooldown does not change upon moving the item to the other inventory.
 * You also cannot use an item that would normally share cooldown with identical items (such as town portal scroll) on Sylla, then pass a second copy of that item from the bear. The second copy will show the same cooldown as the first once it enters Sylla's inventory.

Gem of True Sight
 * Gem of True Sight does not reveal invisible units when held by Spirit Bear.
 * Spirit Bear still drops it on death.

Aegis of the Immortal
 * Spirit Bear cannot pick up Aegis of the Immortal, but can attack (destroy) it.

Runes
 * Spirit Bear can destroy runes, as can any other unit. Spirit Bear can only use invis, haste, and regeneration runes. If the bear attempts to pick up an illusion or double damage rune, the rune is destroyed.
 * Spirit Bear can bottle runes normally but only gains the rune effect from using a bottled invis, haste or regeneration rune. Spirit Bear cannot use normal bottle charges.
 * If Spirit Bear uses a bottled Double Damage rune or a normal Double Damage Rune while within 450 units of Lone Druid, Lone Druid will gain the Double Damage effect.

Skull Basher
 * Spirit Bear can carry a Skull Basher that works independently from any carried by Lone Druid himself.

Trivia

 * Lone Druid's original name was "Syllabear", a pun on the name of Syl-lab-le, one of the developers who worked with Guinsoo. Before retiring, he created this hero. It has now been shortened to "Sylla".
 * Lone Druid, while on True Form, used to have a second sub-ability called One, it equally distributes the damage taken by Sylla and the Spirit Bear, allowing them to endure more damage and live longer.
