These slow effects decay. Basically it means that 15% slow after one second becomes 10% slow, after two - 5% and disappears after three (at least this is how I think "decay" works). However, please keep in mind that "every its [slow's] instance decays separately":


 * Second 1: Sta'Drew applies two stacks of entanglement by 'Higher Justice', slowing by 12%


 * Second 2: First slow had decayed to 8%, but Sta'Drew used whipping liane, slowing Ashe by 18%. 8%+18%=26%


 * Second 3: Ashe isn't rooted, because Entanglement can't affect her (cooldown). First slow decayed to 4%, second slow decayed to 12%. 12%+4%=16%.

Am I correct? I just can't describe it clearly enough...
