Always use it to save your teammates or to kill enemy support

Early Game
Soon or later you will get Aghanim, so you need items that cannot be activated and can give stats and especially passive stats
Must have in any situation, especially when with one aspect you can upgrade it
It always good to have evasion and ability to shut up the enemy
Projectile speed and poison
Core Items
Situational Items
Very rare when you would need it, because you are half support and half carry
Can be good if you would upgrade them in boots of bearing but too expensive receipt compared to items we need
Good item to catch enemies, even if not able to use in second life
If we need more attack speed
To counter dangerous enemies
