Kiwi and Item interactions?

Soooo, how does the roundhouse kick work? More specifically in regards to Trident/Baby Bunny Snowglobe/Eldritch Arms? Does it add a flat number of attacks to the roundhouse? E.g: 10 creeps with Trident is 12 attacks total; so one attack to each, and 2 extra to be spread around. Or does the Roundhouse itself generate one attack per attack interval, applying a multiplicative effect? E.g: 10 creeps with Eldritch Arms is 10 individual attacks, each with +8 for 90 total attacks.

Hey, sorry for the late reply. Each roundhouse kick always attacks all creeps in range. Items that increase targets like Trident of Poseidon or Eldritch Arms have no effect.
