Bugs: Items: Trinket: Hook of the Master Angler / no swim boost and wrong scale size
itemID 19979 [Hook of the Master Angler] when used does not scale the character's fish form to appropriate size (unsure but its left as 1, should be more like 0.3) and you don't get the swim speed boost. Swim speed boost should be 35%
