I have been playing the little fun RPG and since i have been googleing like crazy with no results I'll post what I've found out and what to do! Streetpass: You need to play it and activate it ASAP! Other wise on the rare chance someone you pass has a 3DS that has it activated you and they will gain nothing! So turn it on and hope for the best! People who you street pass more than once gain a level each meeting! Pass friends enough and become more powerful! Heroes: These guys fight enemies to save your Mii. You either have to street pass with another 3DS or hire a hero to fight for you. IF YOU STREET PASS OR HIRE A HERO USE THEM BEFORE YOU EXIT THE GAME OTHERWISE THEY DISAPPEAR FROM USE. These guys'gals vary from Level and shirt color. Level tells how much damage they will give with their sword and their shirt tells what kind of magic they can use AND if a ghost has a shield only the same color hero will break the shield. You can swap heroes in game without losing them so "Send out different Hero" is effective to pick which shirt/magic hero you want to use to fight. Each hero gets 3 sword attacks but only can use a magic attack once! Limit to heroes per Find Mii send out is 10, street passed or Hired... Hire a hero: You can spend 2 of your coins you earn by walking around to hire a hero (to fight and save your Mii. They almost always are Lv. 1 but every so often a more powerful Lv. 2 will show itself. I'LL SAY THIS TWICE IF YOU HIRE A HERO OR STREET PASS USE THEM BEFORE YOU EXIT THE GAME OTHERWISE THEY DISAPPEAR AND THAT WASTES COINS AND STREET PASSES!!! Ghosts: These guys are in each room and you must defeat them to gain more hats and save your Mii Ghost Types: Ghost: Basic baddy...use your sword and attack them Shield Ghost: These have colored shields and only a hero with the same color shirt as the shield will break it! If you have a ton of heroes and know you have one or want to check if you do use swap hero to get one that matches and destroy that shield! A side note some shirts do have magic that does damage to shielded ghosts but it's very weak and only should be used as no other choice Blue Ghost:Weak to red magic (fire) These have higher Hp than regular ghosts... Armored Ghost: These guys are Higher HP AND more defense, Use Lv. 2 or greater (not sure if their is such a thing but just in case) to attack them Lv. 1 does 0 damage, also pink shirt heroes cast a spell that makes the next hero more likely to critical strike (i used it and it happened twice in a row and then missed) Blood Ghost: Immune to fire and have high as crap HP. Weak to blue magic! Armored Demon: Lv 1 do not harm them with standard attacks, Lv 2 only do 1 hp damage per strike....magic and support spells are the only way to a quicker victory Armored Fiend: Same as above but with much more HP ULTIMATE GHOST: It has your Mii! kill IT! no armor but god the HP level on it is stupid high Magic types/Shirt colors: (magic only lasts while heroes are in the room, so if you run out of heroes but a ghost still remains, their HP doesn't go up but the magics effects disappear) (Lv does effect how much damage an attack does just like the sword! might be more helpful to use Lv 1 heroes to support IF you have characters to support that is) Black: Makes the room dark...makes it harder to hit but gives another chance to attack enemy...maybe White: Brightens the Room....only useful in 2nd to last room Pink: Makes next appearing hero Darring!...ups crits at a cost in accuaracy, good if your fighting armored enemies with only Lv. 1 as crits actually do damage against them even if they are only Lv 1. Blue: attacks ghosts with water attack! Attacks all ghosts in room with water, effective against armored, ineffective against blue, very effective against blood ghosts Orange: Moral Boost...Extra attack at the end of the normal 3! Green:Temporarily raises next hero's Strength! Makes next hero that appears level DOUBLE for that room Green-Yellow (looks lime colored): Puts enemies to Sleep...opportunity for an extra attack Yellow: Creates a Sandstorm...makes it hard to attack with sword but also makes enemies rub sand out of eyes for an extra attack...maybe Purple: Poisons Ghosts!..Useful if you use it early with a LOT of heroes, does 1 damage after each round to all ghosts on field Red: Engulfs all ghosts with Fire! effective on blue ghosts and Armored ghosts Light Blue: Traps all ghosts in freezing Ice! Ghost may be trapped in ice for a few turns, very effective against the blood ghost/armored ghosts since they have such HUGE HP Brown: Randomly Summons a Bunny wandering Hero Lv 1 or 2. Good if you have only lv 1 heroes and need to attack armored ghosts, or if you need a different color shirt to fight a shielded ghost. In all honesty hope for luck its no guarantee Unlock-able Hats that I've seen so far CAUTION SPOILERS Warning: Spoilers inside! Mario's Cap Cat Ears Red Pikmin Kirby Link's Cap Dog Ears Samus's Helmet King's Crown Luigi's Cap Took me a couple hours but the walk through is easy enough, lets just say one play through won't get you all the hats. GOOD LUCK!
