So, here's the new and improved "Semi-comprehensive SMBO Guide", current as of the June 21st update. Please fill me in on missing or incorrect data whenever possible.
Rather than scrolling down the entire page to see the main features of the guide, here they are (warning, these are big pictures):
Character Guide -- Enemy Guide -- Item Guide -- Badge Guide -- SMBO World MapCharactersCharacter/Equipment GuideNote that "Total Stat Ratings" are calculated from initial stats and the best character-specific equipment to date. For a breakdown of the stats of these items, as well as an explanation of Stat Ratings, look at the Equipment section below.

Mario’s built for SPEED, but is at least an average character in all respects. Mario has few defined weaknesses, and is probably a good choice for beginners.
Perks:
- Highest overall Stat Rating
- High SPEED stat
- Versatile array of specials, with a 2-FP move and both ATK and DEF-boosting specials
Total Stat Rating: 38.8

Though he shares several specials and some equipment with his older brother, Luigi’s one-to-one HP-for-FP trade sets him apart from the crowd. In addition, Luigi has reasonable equip requirements, cheap equipment, and an affinity for DEF and STACHE.
Perks:
- Highest DEF
- Decently high points in all stats
- Cheap heal special & strongest DEF special
Total Stat Rating: 35.7

The buff and burly Wario’s main objective is to smash his opponents into the ground. His lack of affinity for DEF and late-earned heal special make him awkward to play as at first, but in the long run, he's more than worth the trouble.
Perks:
- Highest ATK, highest Stat Rating discounting SP
- Very few points in "fluff" stats (SPEED/SP/STACHE)
- Ranged weapon and several AoE attacks
- Powerful heal and cheap ATK-boosts
Total Stat Rating: 37.4 (36.4 Ranged)

Much like in mainstream Mario games, Waluigi’s a rather awkward character. His main focus is on STACHE, giving him a lucrative glass-cannon playstyle. His ranged weapons can be quite useful in dispatching of enemies from a distance.
Perks:
- High STACHE and shop discounts
- Two ranged weapons and high-ranged specials
- ATK- and DEF-reducing specials
- Can benefit immensely from the Heal Power badge
Total Stat Rating: 34.0 (32.0 unranged)

Yoshi is one of the best characters to play as, as his affinity for FP and phenomenal special attacks often work together to greatly simplify otherwise difficult encounters. Yoshi has the only heal special that gives a greater than 1-to-1 exchange of HP for FP, making leveling on Lakitus and such quite lucrative. Yoshi has no defined disadvantages, and as an added bonus, you can use spray paint to further customize your character.
Perks:
- High HP and highest FP
- Most cost-effective heal
- Incredibly worthwhile specials
Total Stat Rating: 36.6

Toad’s an unlikely fortress, as his naturally high HP and DEF make for an interesting time for your opponents. Coupling that with his fourth special, Toad easily has the most of control over PvP. Toad’s most prominent weakness is his general lack of ATK, but that can be remedied through the aforementioned special. Toad’s hard to place in the lineup for character ranking, as his performance is largely based on your desired strategy, and he is meant to be more of a supporting character.
Pros:
- Highest HP
- Ranged weapon
- Unique ATK-DEF Swap special
- Only ranged heal special, great for support
Total Stat Rating: 35.7 (34.4 unranged)
I elected to omit the tier list this time around, as aside from Wario and Toad, the characters seem very well balanced this time around!
Note: "Stat Ratings" are an approximate measure of the relative worth of equipment/characters. Each 1.0 Stat Rating = 5 HP, 5 FP, 1 ATK, 1 DEF, 2 SPD, 2 STA, 5 SP, or 3% Critical or Block Chance.
Items & EquipmentThis very efficient and thorough chart lists all equipment, special attacks, items, and badges currently in the game, as well as Stat Rating info and various other miscellanea.

Enemy GuideHere are some general formulas for various aspects of SMBO's battle system, for the curious:
Damage done:
(ATK(*.6 + Base) - DEF)*DM*DM +/- 2
DM = 1 normally, 1.3 w/Damage Up, 0.7 w/Damage Down
SP:
Base + 2*(# of Levelups) + 3*SPEED (Total)
1 SP every ~120ms (Drain)
(SPEED/2) SP every 3 seconds (Regen)
Attack speed:
1,000 - 3*SPEED milliseconds (- Equipment)
Crit/Block chance:
0.40*(SPEED or STACHE) percent (+ Equipment)
X-hit KO requirement:
Rdup((Rdup(Enemy HP/X)+2)/DM)+Enemy DEF
DM = 1 normally, 1.3 w/Damage Up, 0.7 w/Damage Down
World Map & FavorsThis is a semi-comprehensive map of the game as of its most recent update. For better quality, follow the direct link
here.
-- Mushroom Kingdom Favors --For the first favor, give the Toad at the point indicated three Koopa Shells to gain access to the warp in the dark purple house, and thusly the HP Plus Badge.
For the second, talk to the Toad in the indicated location, then kill 10 Lakitus in the same screen (not necessarily in one life). Talk to the Toad again to receive 100 coins.
For the third, talk to the Toad, then head to the screen with seven Piranha Plants and look behind a tree for the Mushroom Toy. Give this to the Toad to gain access to warp #7, and the second half of Koopa Beach.
For the fourth, talk to the Salestoad to find out that his sick friend has his goods in a package. Go to the Restoration House and talk to the Toad in the right corridor to have him give you the package. Return it to the first Toad to gain access to the shop containing the third set of equipment.
For the fifth, talk to the Koopa in the house indicated and give him three Drillbit Shells in exchange for five Melons, rare items which stack and give 10 HP apiece.
For the sixth, retreive the envelope for Toadsdale after hitting the four switches.
For the seventh favor, deliver the Toad ten Pokey Flowers, in exchange for 400 experience points and 10 Dim Star Pieces.
For the eighth, talk to the Toad in the northwest corner of the town, then talk to the other Toads to eventually receive the Goomba Toy. Give this to the first Toad to receive a Pokey Card.
For the ninth favor, deliver the red-capped Toad the package of Super Shrooms (located in the upper-right corner of the screen two screens west of the vine pit). In exchange, you will be able to buy them in Kinopio Village and the Mushroom Kingdom.
For the tenth, deliver a Shroom Cake to the Toad outside of Flower Hills. In exchange, he'll allow you to sample his wares.
For the eleventh, return the Salestoad's lost goods to open up his shop. To obtain them, attack the green plant in the upper-left corner of the left screen with pipe 49.
-- Beanbean Kingdom Favors --For the first favor, simply give this Bean a Rock, dropped by various enemies in the area. He will reward you with a Rock Candy.
For the second, return Chef Bean B.'s Frying Pan, located in a ? block accessed through one of South Beanbean's caves.
For the third, give this old man the ten Bean Fruits in exchange for a Wrench, Ultra Nuts, 150 BB coins and 300 EXP.
For the fourth, return this Wrench to the Bean in the Pipe House in west Castle Town for 100 BB coins and 500 EXP.
For the fifth, simply talk to the guard after finishing the first four favors, and he'll let you pass through whenever you like.
For the sixth, bring a Memory Cake, a special recipe cooked with a Refreshshroom, to the amnesiac to buy equipment from him.
Other notes:
- The three points marked in the Mushroom Maze inset are a Moderately Weak Mini Bob-Omb, a Moderate Mini Bob-Omb, and the point where the former is used, respectively.
- Warp 16 is a Bullet Bill cannon, and is illustrated as a yellow/red warp for simplicity’s sake. To make the Golden Bullet Bill appear, you will first need to find the clues to its location, the first being located around cacti in the bottom-right of the screen one screen east of the cannon, and the second in front of a small cliff in the screen one screen south of the cannon.
- The spray can opposite the card shop is where Yoshi and Toad can have their skin/cap color changed.

5 cards = 100 coins

Legend should explain it all; there are three DE Koopas before the pipe, and seven afterward.
