Hey Ahri players I found your lost 20% damage amp! Come get it!

Chum the Waters (R) : The fish now also amplifies Fizz's damage (except for Chum the Water's "shark" damage) on the target by 20% for 6 seconds

Urchin Strike (Q) magic damage decreased to 10/25/40/55/70 (+.3 AP) from 10/40/70/100/130 (+.6 AP)
Seastone Trident (W) passive 's damage changed to 20/30/40/50/60 (.45 AP) from 30/40/50/60/70 (+.35 AP)(+4/5/6/7/8% of missing HP as magic damage) over 3 seconds
Seastone Trident (W) active's on hit damage changed to 10/20/30/40/50 (+ 4/5/6/7/8% of target's missing health as Magic Damage) from 10/15/20/25/30 (.25 AP)
Seastone Trident (W) active no longer applies Grievous Wounds to the target.

(it's kinda mathy and all that, but in short, W's power is pushed into it's active portion, and it lost grievous wounds)
