Galio Ultimate Question

ACTIVE: Galio becomes a statue and channels for 2 seconds, Taunt icon taunting nearby foes and reducing incoming physical and magic damage by 50%. When the channel ends, Galio bursts out of his statue form, dealing magic damage to enemies within range. The damage is increased by 10% for each attack suffered while channeling, capping at 80%. If the channel is canceled, the damage radius is reduced to 575 instead of normal.

''each attack suffered while channeling'' ? Does it include any sort of attacks? Minions, Barons, scruddle? :D , Turrets?
