Aspect of the Serpent can effectively increase Cassiopeia's ability powerup to 30%. so if 1.30*1.30=1.69*1.05=1.77 adding *1.06=1.88 is mathematically correct tested in a game and it was actually correct no idea what DarkSigi is talking about
 * Aspect of the Serpent's stacks multiplicatively with both   Rabadon's Deathcap  and   Archmage . The three combined increase her ability power by 77.45%
