How to unlock the Loot! achievement in Sly 3: Honor Among Thieves - Definitive Guide
These three trophies are all connected to how much you "currently" have, not how much you've gained and spent. The higher the value, the harder it is to get at first. Best chance to get this early on would be from hoarding everything, but I managed to get this by as early as in China going after General Tsao. Most of the guards have a chance to carry either gems or gold, and they sell very well. If you wait until later, the next episode actually offers a much greater chance to gain loot, though with a bit more work.
You must have all at once. So I would advise you to not purchase anything until you have gotten this trophy. If you are having trouble rounding up the required coin for the moves, I suggest go pickpocketing for items - they offer a decent bit of change and the enemies carry better loot for you to pickpocket as the episodes progress. You will know when a person has a rare item when their pocket shines bright.
Episode 5, there is a time where you get a boat, when using the boat and on sea, take out as many boats as you can to rank in the coins to purchase more abilities.
Episode 2 (Rumble Down Under), there is a mission where you play as Murray and you have to feed guards to an alligator. The enemies are unlimited as long as you don't feed them to the alligator just yet.
Just keep spamming the face buttons to knock out guards and pick up the coins they drop. I had 1000 when I started the mission and within 25 minutes, the loot trophy popped. This way you have the trophy early on and you can start buying new moves if you want to. Thanks Alex 92 for the tip.
