A bandit named Misko has hidden treasure all over Hyrule. In this guide, we'll be focusing on the Phantom armor, taken from The Legend of Zelda: Phantom Hourglass on the DS.
When you load up the game after purchasing and installing the DLC, bring up the side quest menu and set a waypoint for "EX Treasure: Phantasma." This will set a waypoint for the first objective on this quest, but after that you're on your own.
Head to the waypoint and you'll find a destroyed building. Go in there to find...
These notes contain tips for a few different masks and armor pieces, but here are the details for the Phantom suit:
"I hid the eight priceless relics I stole from Hyrule Castle in treasure chests...I shall write down their locations. -Misko
Armor worn by fierce phantoms, feared even by heroes, is hidden in the ruins of Hyrule Field. Find these pieces at a battleground where brave souls tested their skill...at ceremonial grounds where royal guards are honored...and at the ruins where the soldiers of Hyrule gathered."
These refer to the Coliseum Ruins, Hyrule Garrison Ruins, Sacred Ground Ruins.
It's wise to tackle these in reverse order (which, incidentally, I did not do, which is why I am already wearing the Phantom helmet in the screens below). The Sacred Ground Ruins are right outside Hyrule Castle, and if you've been memory hunting, you've probably been there already. The spot is very easy to identify on the map because of the surrounding water.
Warp to the nearest tower and paraglide in (don't worry too much about Guardians shooting at you from the air - they'll have a very hard time hitting you). There are other Guardians patrolling around, but there are spots to take cover if you get seen.
The chest is in the surrounding moat. You'll need to use magnesis on all of the chests planted by this first DLC pack, so pluck it from the water.
Phantom Armor! This boosts your attack, and can't be replaced if you sell it... which is true of the whole set, actually.
Next we're heading for the Hyrule Garrison Ruins, which you are less likely to have visited before (although if you have, the name of the place will be marked on your map when you zoom in). On the map above, I am standing in the ruins.
As before, warp to Central Tower and float down in this direction. The Garrison is large, so it's fairly easy to spot.
There's a Guardian here, and he's a little harder to avoid than the ones near the sacred ground. You can be sneaky if you'd like, but chances are if you've been playing the game since launch you're pretty well equipped to take him down. Remember to deflect those lasers!
The advantage of taking down the Guardian is that the area is crawling with treasure, like this Knight's Shield...
....this rusty sword...
...and a silver rupee. Have a good look around if you haven't before.
On the outer edge of the garrison is a downed Guardian, which seems to have smashed right into a building. The chest is buried behind it, so go in there and grab it.
Now you have the Greaves! Once again, don't sell these.
Finally, the Coliseum. This is south on your map, near the Outskirt Stables. It's also near the game's starting point, so if you're anything like me you stumbled in here early in the game and ran right out when you saw the fierce beasts in there. The chest is on the ground floor, which is, of course, protected by...
...a Lynel. A particularly hard one, that shoots fire and has 5000HP. You can fight it, of course - in which case I'd advise dropping in from the top of the Coliseum and showering it in bomb arrows before you start just to make a dent in its HP, or...
...you can sneak your way in. The treasure is actually fairly near the entrance, and if you don't make yourself known to the Lynel it will leave you alone.
When you walk in, the treasure is to your right, behind a pillar, buried. Sneak behind the pillars here and pull it out. If you're having trouble finding it, remember that switching on Magnesis highlights objects you can grab.
There it is! The set is complete now. By the way, while you're here, the upper levels are full of less powerful enemies with awesome weapons - kill a few Lizalfos and take their Royal Shields!
Take the helmet off if you want Link to show reactions and emotions during cutscenes, otherwise enjoy the armor strength and attack boost of the Phantom set!
