Terrorblade

Use your reflection when your support is harrasing the opponents or in combination with Metamorphosis to inflict greater damage.

Feel free to pop Metamorphosis to give yourself an easier time lasthitting for two waves, Try to harras your opponent and deny they're creeps.

Make sure you have 2 levels in metamorphosis before your second use of it in lane.

Stay healthy as illusions will inherit your hero's current health.

Don't overlane. Consider moving to the jungle when laning opponents are about to hit level 6.

You can also Sunder an ally or illusion when in trouble. You can body block an opponent with illusions as well.

Farm dangerous areas with illusions, control runes and provide vision when opponents are missing.

Pop Metamorphosis only when opponents are committed to the fight. It can get kited if you pop it too early.

Push out sidelines and farm opponents' jungle with illusions when not much is happening around the map.

Terrorblade has high armor, but low HP and is weak against magical damage. Pressure him early on.

Terrorblade is strong when he has Metamorphosis on. Look to escape and fight afterwards.

Hexes, drains and Dagon destroy Conjure Images instantly.

If you are high on HP, avoid staying close to Terrorblade when he is low as he will Sunder you.

Terrorblade farms quickly with Conjure Image. Smoke on him, place deep wards and sentry off camps.

Items that provide AoE damage, especially magical damage, are great at dealing with Conjure Image.

Crimson Guard and armor items are great against Terrorblade's physical damage.

Black King Bar, Linken's sphere or a well timed Lotus Orb prevent you from being Sundered.

Terrorblade is great at split-pushing and ratting. Consider getting Boots of Travel on a core.
