Dota – How does Slark’s autoattacks go trough Pugna’s Decrepify

dota-2

I've just played a match (62958817) with Pugna which had a enemy Slark. In multiple occasions, when he was about to attack me, I'd use Decrepify (immunity to autoattacks + can't autoattack + 40% more magic damage received) to defend myself, but it seems that either applying it to him or myself is ineffective, if not increasing the damage I take (when applied to me). While reading trough Slark's abilities, I couldn't find any hint of why would his autoattacks be counted as magic damage.
His build was constituted by the following items:

  • Assault Cuirass
  • Power Treads
  • Bottle
  • Sange and Yasha
  • Skull Basher
  • Shadow Blade

None of these appear to give magic damage in their tooltip. It's also worth noting that while he did cause normal damage, I wasn't affected by Skull Basher at all.

How did he bypass that immunity?

Slark's Dark Pact removes the Ethereal debuff that Decrep applies, allowing him to attack you.
