How do the Treasure Goblins work?
Treasure Goblins are feisty little monsters that drop gold trails as you chase them around, and explode in a giant explosion of coins and loot when you finally bring them down.
Is the gold the goblin drops while fleeing separate from their "on-death" spoils, or does it get drawn from the same pool? If I want the most gold from the Goblin, should I kill them immediately, or wait for them to litter the ground with gold a bit, first?
How do the Treasure Goblins work? explains what they are, and their general behavior, but I know that already; I'm more interested in the strategy that milks the most coins from their grubby little paws. Should I obliterate them ASAP? Or should I let them leave a trail of coins for as long as possible before offing them?
