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 also use Leech Seed against a target, dealing moderate damage over time to it and slowing it whilst 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 affects enemies in a respectable area of effect and entangles enemies with vines, branches, and roots; though it does not deal any damage, it will immobilize them and render 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 rooting a path to victory.

Tips

 * Using Nature's Guise 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 Sentry Wards to prevent this.
 * Your autoattack animation and rate are slow, but pack a huge punch. With a little practice, you can put that power to use and greatly assist your lane partner by denying units.
 * Living Armor can heal buildings. If you have time, and no one else requires it, cast Living Armor on damaged towers. Granted, the ratio of health gained to total health of buildings may be small, but its duration is as long as its cooldown, so you can keep it constantly regenerating health, provided you have enough mana.
 * Although he is quite tanky, his offensive output is very minimal and once he has initiated with Overgrowth he should conceal himself, firing Leech Seeds from nearby trees (keep in mind at all times that Roof can use abilities without breaking his invisibility).
 * In a gank, use Nature's Guise to sneak around behind the enemies, as if Leech Seed is used on an enemy running towards you instead of away from you escape will be almost impossible; to say nothing of Overgrowth.
 * In most circumstances Rooftrellen 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 Soul Ring is a good early pick-up for Rooftrellen, 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.
 * You can cast spells when you're invisible with Nature's Guise. If you are equipped with items with powerful active abilities, like Necronomicon, Shiva's Guard, and Scythe of Vyse, you can use this to surprise and play tricks on your opponents, as long as you stay near the trees
 * Your high Strength and attack damage is great. You can purchase attack boosting items like Assault Cuirass, Battle Fury, Armlet of Mordiggian, Satanic, Mjollnir, Abyssal Blade or Mask of Madness to improve your damage output, if your team is deprived of powerful attackers.
 * Altough he's not the best, Treant can be a good jungler because of his high base attack damage and Living Armor damage block, Leech Seed in case of his hp dropping low and Nature's Guise to initiate ganks. It will give the team another solo lane, more gold for him than playing in a dual lane and the ability to keep healing towers with the global living armor when don't needed while in the jungle.

Trivia

 * Rooftrellen has "Riki was 'ere" carved into his side (near the right handed runes on his belt).
 * Treant Protector's appearance, name, and voice are based heavily on Treebeard, the eldest of the Ent race, who appears in the Lord of the Rings books and movies.
