Mission 34: Eliminate the Aerial Masters
Mission 34 in Kingdom Hearts 358/2 Days takes Roxas back to Agrabah for an extermination mission. Despite Saïx saying that Roxas would be working solo after spending much time with Xion, Roxas embarks on this mission with Demyx.
Aerial Masters have surfaced in the desert. Team up with Demyx, and eliminate them all.
Enter in the Agrabah Streets. There will be no enemies around, so now is a good time to snag the chest and Ordeal Badge. Alas, you will probably lack High Jump the first time through, and so the chest on the west scaffold will be unreachable at the moment. Continue on to Agrabah Gate. The first Aerial Master will be here, accompanied by a few Loudmouths. You will probably want to take them out first, as they can easily heal the Aerial Master through sheer numbers alone. Grab chests and then head out into the Sandswept Ruins.
The three remaining Aerial Masters will be scattered through the large area of the Ruins. One will be in the northwest corner near the sand falls, one will be in the very south end of the Ruins, and one will be in the east, between the two buildings near the east wall. There are no Loudmouths in this area, but there are Scarlet Tangos, so watch your back for Fire magic. The Unity Badge is not too far from the entrance, and it should be easy to pick up.
When you head back to the RTC point, beware. A Large Armor replaces the Aerial Master in Agrabah Gate. If you need extra heart points, you can take out him and his Loudmouth companions. If you really want extra heart points (or a Combo Tech), you can go back into the Sandswept Ruins and fight a Zip Slasher. Otherwise, head onto Agrabah Street to finish things out.
For this mission go in with plenty of Magic casts equipped (namely Blizzard, Fire, and Cure or Cura) and a Keyblade that specializes in a higher magic stat. Equipping Haste and Air Slide can really help here for moving around quickly. First deal with the Aerial Master in Agrabah Gate, then the remaining 3 at Sandswept Ruins. For these 3, as long as you know where they will appear, then it can help save time. Ignore other enemies as best you can and attack Aerial Master with Blizzard or Fire. Having them frozen can help increase Fire's damage, and any assist you get from Demyx is helpful. While not overall too difficult, if you are having trouble getting back and using the RTC point in time, then wait until later where you can have a better magic stat to use at a much higher level.
