Tips

 * In light of this, if you expect your Level 1 Diffusal to run out of charges in the middle of a fight, lock the Diffusal and buy the recipe beforehand. Unlock it in the middle of a fight once you run out of charges.
 * Combine it with a to get both of the most cost effective DPS items in the game, to burn mana much quicker with the attack speed and lifesteal from the mana burned. The active of the Diffusal Blade will slow your target to hit more.
 * It is a good item combined with a Manta Style because illusions carry over Manabreak, increasing damage output. Combine this with (works on illusions if not consumed) to burn mana much quicker and increase DPS even more.
 * The Diffusal movement slow allow to hit and run enemy melee heroes as ranged.
