Item - Hunter T16 4P Bonus Explosive Shot casts have a 40% chance to not consume a charge of Lock and Load. Instant Aimed shots reduce the cast time of your next Aimed Shot by 50%. Offensive abilities used during Bestial Wrath increase all damage you deal by 2% and all damage dealt by your pet by, stacking up to 15 times.
The last line is either missing a separate percentage for pet damage or is also 2% stacking 15 times.
2 set was buffed from 2 seconds to 12 seconds of reduction per cast.
