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 at his will, he can grant invisibility and stealth to himself and his allies with Nature's Guise and replenish their health with Leech Seed which also slows and damages his prey. His Living Armor bless his allies with natural protection, giving them bonus health regeneration and damage block. His scariest feature is Overgrowth, though it doesn't deal damage, Rooftrellen summons vines, branches and roots to entangle his enemies, making them helpless and unable to attack for a long time. With Treant Protector at your side, allied support will come and greatly assist your team for 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.
 * 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 it's duration is as long as it's 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, Mjolnir, or Abyssal Blade to improve your damage output, if your team is deprived of powerful attackers.

Trivia

 * Rooftrellen has "Riki was 'ere" carved into his side (near the right handed runes on his belt).
 * Treant Protector is known to have the most skill revisions in the game:
 * Eyes of the Forest, his old second ability, creates a mental link to the trees, giving him vision over that area and reveal invisible units. This is similar to sentry wards, except it can only be placed in trees.
 * Forest Sentinel, another old second ability, lets him summon a forest spirit in an area that acts as an invisible watcher, granting him extra vision and True Sight for 8 minutes. Any enemy who comes contact with the Sentinel will be damaged and stunned.
 * The first Living Armor magically creates an armor of vines, giving his allies or himself bonus health regeneration and armor. It can be auto-casted.
 * Overgrowth used to be a literal Entangle variation that disables targets for 5 seconds, while dealing huge damage. It was changed and modified over time.
