Treant Protector

Rooftrellen the Treant Protector is a melee strength hero who excels in supporting and strengthening his allies with his beneficial set of spells using the power of nature. He is a natural tank, offensively and defensively, having both the highest natural attack damage, and the second highest overall strength in the game. Manipulating the power of the plants to his will, he can grant invisibility and stealth to himself and his allies with Nature's Guise, provided that they remain within close proximity to a tree. He can use Leech Seed to sap the life from a target, slowing and dealing moderate damage over time to it while nearby allies are replenished by the same amount. His signature Living Armor makes him truly live up his title, as he is able to provide allies and even friendly buildings increased health regeneration and a massive damage block from anywhere on the map. Finally, his ultimate Overgrowth roots nearby enemies with vines, branches, and roots; though it does not deal any damage, it immobilizes them and renders them unable to attack for several crucial seconds. Although Treant Protector is not able to dish out much damage outside of his regular attacks, he is able to provide an enormous amount of defensive utility and survivability to himself and his teammates, thereby planting the seeds of a decisive victory.

Tips

 * Using on allies during a gank gives them the element of surprise, and owing to the extremely variable nature of this mechanic the enemy team will struggle to use s to prevent this.
 * If time permits, Treant Protector can use it on his whole team just before a team-fight to obtain a similar effect like . This enables his team to properly initiate assuming that the enemy team does not have detection or they did not see Treant cast it.
 * Keeping an eye on the minimap is important, may make the difference between a farmed team-mate or a farmed enemy. If a team-mate is getting ganked, casting Living Armor on them can discourage the enemy from continuing or even remove the need for the team-mate to retreat and enabling them to farm more.
 * Treant Protector's attack animation and rate are slow, but pack a huge punch. With a little practice, he can put that power to use and greatly assist his lane partner by denying units. A will also help secure last hits which the carry might have otherwise missed or denied by the enemy, or when Treant happens to lane alone.
 * can heal buildings. If time is at hand, and no one else requires it, it should be cast on damaged buildings. Granted, the ratio of health gained to total health of buildings may be small, but its duration is as long as its cooldown, so it can be kept up constantly, regenerating its health, provided Treant Protector has enough mana.
 * Although being quite tanky, his offensive output is very minimal and once he has initiated with he should conceal himself, firing Leech Seeds from nearby trees (keep in mind at all times that Treant Protector can use abilities without breaking his invisibility).
 * In most circumstances Treant Protector is most wisely built to maximise his abilities' usage, his lack of mobility and damaging spells mean he is best suited to securing kills for his allies via his slowing and disabling abilities.
 * A is a good early pick-up for Treant Protector, as it allows him to spam his Leech Seed as an effective harassment tool while also healing off the damage from the Soul Ring. It also helps solve his mana problems early to mid game. This could also be picked-up if opting for a  instead of an Arcane Boots if team-mates do not need the extra mana. Choosing Tranquil Boots over Arcane Boots makes it easier for Treant Protector to roam the map and regenerate health between ganks.
 * This could also be built into a if the situation permits. It enables him to use his Nature's Guise and Living Armor without worrying about mana consumption.
 * Beside spells, Treant Protector can also use active items while invisible with Nature's Guise without breaking it. If equipped with items with powerful active abilities, like and, they can be used to surprise and play tricks on opponents, as long as Treant Protector stays near the trees.
 * Treant Protector has naturally very high strength and attack damage. Attack boosting items like, , , ,  or  can be purchased to make use of his heavy damage and improve his damage output, if his team is deprived of powerful attackers.
 * Although not the best, Treant Protector can be a good jungler because of his high base attack damage and Living Armor, Leech Seed in case of his health dropping low and Nature's Guise to initiate ganks. It gives the team another solo lane and more gold for him than playing in a dual lane.
 * An gives Treant Protector a free permanent mini Observer Ward every 25 seconds and he can use it to gain vision in critical spots. This could be an enormous advantage for the whole team especially if whem covering the whole jungle and lanes with it. This also reduces the necessity for diving in to Initiate team-fights as it enables Treant Protector to use Overgrowth globally.
 * Purchasing a in conjunction with the Aghanim's Scepter allows Treant Protector to enchant trees in a middle of a cluster potentially deterring enemies from destroying the enchanted tree.
 * It is also possible to use enchanted trees to farm up the enemy neutral creep camps, by enchanting trees near their camps and using Overgrowth. Not only does this boost Treant Protector's gold income, it also denies the enemy team their jungle, effectively taking away gold from them. It is more important however to first enchant trees at key spots to make use of the vision it grants, which is more helpful for the team. Besides that, it should only be done when being sure that Overgrowth is not needed in a fight within the next minutes while it is on cooldown.
 * One Iron Branch carried in the inventory can be used to create a tree, enchant it and cast overgrowth in the middle of battle. Whether one second delay is worth the damage is up to player to decide.
