Reflection
Terrorblade brings forth an invulnerable dark reflection of all enemy heroes in a target area. Affected enemy heroes have movement and attack speeds slowed and attacked by their reflection.
Abilities, roles and builds with an explanation for every purchase.

HERO GAME PLANI split my farm with illusions and pressure during Metamorphosis while keeping Sunder available.
With Terrorblade, nothing is as it seems. Conjuring powerful illusions to confuse enemies and break their defenses, the demon marauder can exchange health with foes and friends to stave off death or weaken his enemies.
My recommendation is a starting point. We choose another position together with the team and for its needs.
I need protected farm, my item window and damage on important targets.
This is an editorial starting plan based on hero mechanics. It is not presented as a match I have already tested or a popularity ranking.
Here is my initial plan: I do my role's job first, then choose the items the team needs. I adapt the order and expensive purchases to the opponent.

Provide attack speed and switchable attributes for farming and managing my resources.

Provides illusions for pressure and a separate dispel. This item cannot help you wait out or remove every disable.

Improves attributes and lets attacks keep a target under control, limiting suitable sources of its restoration.

Provides a window for my actions against eligible magical damage and disables. I check effects that pierce the protection.

Increases physical damage and protection against suitable attacks. I check whether the enemy has an answer to evasion.

I do not assign one ‘correct’ minute to every purchase. I look at my gold, the next fight and the problem: am I missing mana, target access, control or protection? If an expensive slot will arrive too late, I get a useful answer earlier.

Creates an illusion of Terrorblade that deals damage.

Terrorblade transforms into a powerful demon with a ranged attack. Any of Terrorblade's illusions that are within 1200 range will also be transformed by Metamorphosis.

Severs the life from both Terrorblade and a target hero, exchanging a percentage of both units' current health. Some health points must remain.
These abilities are not necessarily available at the same time. I check the condition beside the name: innate ability, another form or an Aghanim purchase.

The hero spends a portion of his current health to grant himself and nearby illusions bonus movement speed, attack speed, and health regeneration. Does not affect the copies created by Reflection.
Costs part of Terrorblade's current HP to cast, providing Terrorblade and nearby illusions bonus movement, HP Regen and attack speed. Does not affect Reflection illusions. Can't be cast while in Metamorphosis and Metamorphosis will remove Demon Zeal.

Causes a wave to travel outwards in all directions forcing enemy heroes to become Feared upon impact and dealing damage, and grants Terrorblade Metamorphosis for a short time.
