Re: Sword and Sweetie (ソード アンド スウィーティー ~果てしなき欲望~)
I noticed that when you're leveling up your black and white magic, it corresponds to the level you're at. For instance, level 3 has a bunch of light enemies, so if you're leveling up white magic, you'll get light resistance, if you're leveling up dark magic, you get a shadow bolt. Dunno if that was obvious or not but just wanted to share my finding because this game is kind of hard to stop playing. I also wanted to post what each spell does and weaknesses for future reference.
Each element beats its opposite (Wind/Earth, Fire/Water, Light/Dark) and resistance its self,I noticed that it's not that big of a difference early on but becomes more prominent later.
Update: Using magic on a enemy of the same element will heal them for some health so be careful with AoE attacks.
Black Magic:
All Black magic has a reddish, pinkish background behind the icon. More for offensive purposes.
Bullet Shaped Icons: Some sort of bolt, does damage to a single target.
Brown = Earth LV1.
Blue = Water LV2.
Black = Shadow/Dark LV3.
Green =Wind LV4.
Red/Orange = Fire LV5.
Yellow = Light LV6.
Weather Icons: Not sure if they effect gameplay, but they at least change the weather

.
Sun:Clears the weather Day or Night.
Umbrella: Makes it rain, thankfully not men.
Moon over water: Makes it night time.
Sun over mountain: Makes it day time.
AoE Attacks: Same idea as the bullets, only a bigger area capable of hitting multiple enemies.
3 Brown Bullets: Earth AoE LV7, Meteors!
Mist looking thing: Water/Ice AoE LV8, Black Mage used Blizzard, It's Super Effective!
3 Black bullets: Shadow AoE LV9, Dark Meteors!
Lightning bolts: Wind AoE lv10, Freaking lightning.
Red cloud looking thing: Fire AoE lv11, Pretty sure this is just an explosion.
3 Yellow Bullets: Light AoE lv12, Best part is the pretty white explosions on the ground.
Heavy Damage Spells: These do massive damage, but take longer to cast and have a longer cooldown. The Wind and Water Versions can hit multiple enemies when cast. Combine these with white magic buffs to blow everyone up!
Spikes: Earth Lv13, They're Stalactites, or stalagmites?
Blue line: Water lv 14, Long blue line.
Black eye: Shadow lv 15, Makes your enemies become the center of darkness.
Lightning Bolt: Wind lv 16 at least it's not a green line.
Super Nova Explosion looking thing: Fire lv 17, Pretty much a super nova.
Sun Exploding: Light lv 18, Wait, this one might technically be a super nova.
Other: There's a teleportation spell which is really useful, has a person figure standing in the middle of a circle.
White Magic: All white magic had a yellow background behind the icon. Support and defense goes this way.
Resistance Spells: Increases your resistance to one element, but lowers the opposite by the same amount, I don't relly use these since the game likes to CC me to hell.
Crescent curvy, green thing: Increases Wind Res. Decreases Earth Res. LV1
Fire with a Circle: Increases Fire Res. Decreases Water Res. LV2
Yellow Cross with Circle:Increases Light Res. Decreases Dark Res. LV3
Rock with a Circle: Increases Earth Res. Decreases Wind Res. LV4
Water With Circle: Increases Water Res. Decreases Fire Res. LV5
Black Gear with circle: Increases Shadow Res. Decreases Light Res. LV6
Healing: Who doesn't like healing?
Heart: Restores some health.
Snowflake: Reduces EP (Ero points? Excitement points? Whatever it does, it removes those hearts on your Character portraits.).
Heart with Crossbones: Reduces the effects of poison and eventually will completely cure it after 2 or 3 casts or at higher levels.
Girl with Sparkles: Cures that stupid Debuff that makes you trip.
Big ol' Heart: Restores a lot of health.
Big ol' snowflake: Reduces EP a lot.
Really Big Snowflake: Reduces EP a ton.
Really big Heart: Pretty much a full heal.
Hearts in a spell circle: Healing over time, pretty good.
Blue Cross in a spell circle: Restores mana over time, Pretty OP, who needs mana pots!?
Golden Cross: Resurrection, Kind of slow to cast, long cooldown, I think the pots are less hastle.
Imbue: Makes your Weapon the Corresponding element... I assume.
Rock with Star behind it: Makes your weapon rock element. LV7
Water with Star behind it: Makes your weapon Water element. LV8
Black Gear with Star behind it: Makes your weapon Shadow element lv 9
Green Cresent with Star Behind it: Makes your weapon Wind element lv 10
Fire with Star behind it: Makes your weapon fire element lv 11
Yellow Cross, with a star behind it I assume: makes your weapon light element. lv 12
Buffs: Shame you get these so late, it powers up your character and makes the game easy mode, more than it already is.
Glowing Red Sword: Gives a Temp. Attack boost, and makes you too strong.
Glowing Red Staff: Gives Temp Magic Damage boost, also makes you too strong.
A sword and its afterimages: Lowers your cooldowns for more dunks. spacejam.mp3
Shield: Not too sure about this but I'm guessing an overall defensive bonus temporarily.
Pink-Purple Magic circle: Not sure about this either but I'm sure it gives you some Magic all around magic resistance temporarily.
Target/Crosshairs: Temp. Accuracy boost, Makes your dunks hit 100% of the time.
Running Stick Figure: Makes you go faster temporarily, like Sonic, Cityescape.mp3
White Wings/Feather: I have no clue, someone tell me what this does.
Other: You get this one spell that has a ball of light looking icon, It's a really slow light based attack, outclassed by Black Magic Light bolt.
That's all I have so far, dunno if it'll help anyone but I'm hoping someone will benefit.
UPDATE: Posted the rest of the spells, beat the game, final boss was a pain. Thank god for all those OP buffs, gotta go fast.
