Diffusal Drow

From the creators of Diffusal Windranger and Diffusal Morphling, i came with this question

Why people like RTZ are building this item on drow ? just because with the Manta Style synergy?

Drow already has a built in slow, sure cheap agi and dispel/mana burn make sense on her but it just does not explain by itself

Can someone explain this to me ?

saw this first time in this game on dota pit: https://www.youtube.com/watch?v=UNA2C_Nrh3c

I'd definitely say the Manta synergy is there, as well as it being fairly cheap for the stats and abilities you get, lie you said. Diffusal gives 25 agi + int and purge/slow for 3150 whereas an Eaglesong gives only the 25 age. for 3.2k. Then you can purge the slows and DoT that is really detremental to Drow playstyle, seeing as she is so squishy and lacks an escape.

So yeah the points you brought up are the reasons why. Cheap and useful.

I think it's only because of the strat they chose for the game, which is Drow + Visage push strat. So Drow goes full AGI for the aura, buying all the AGI items, and Diffusal gives the most for a rather cheap cost. I'd say the Manta synergy doesn't even matter in this case, because he didn't buy the full item. Also he could dispel Cold Snap and Ion Shell, and later Ghost Scepters.
