Fire
Warmaster's Burst
The top option for Fire. Much like Destruction-Burst below (Compression section) it sacrifices HP for damage, but you pay for only 45% with HP, with +5% Mastercraft for a total of +50% damage.
Location: Today's Event -> Burning Solstice -> Burning Solstice Part 5
Water
Cysero's Explosive Teleport Booth (PREMIUM)
This is the best option; it seeks between water and energy, and it has the same mechanics as Destruction Burst, dealing 50% more damage at the cost of a tiny amount of HP. Unlike Destruction Burst however, it requires you to buy a Z-Token package.
Location: 12000 Z-Token package

Lagoon Leviathan (RARE)
Strongest non-premium Water Spell, having a neutral lean with a 20% chance of dealing +25% damage.
Location: None
Info-Subs: Link
Whirl Tide
If you can't buy the 12000 Z-Token package, or don't have Lagoon Leviathan then this is the best alternative to Cysero's Explosive Teleport Booth. It has a +6 BTH lean and a +4 BTH MC, and consists of 9 equally powerful hits. However, it deals no more damage than a regular spell.

Wind
Warmaster's Burst
The top option for Wind. Much like Destruction-Burst below (Compression section) it sacrifices HP for damage, but you pay for only 45% with HP, with +5% Mastercraft for a total of +50% damage.
Location: Today's Event -> Burning Solstice -> Burning Solstice Part 5
Borrow
The best Wind Spell outside of premiums. While it out-damages even Arctic Tornado, applying a *1.5 multiplicative boost instead of +50% additive, but at the cost of the monster healing all of the damage done over 5 turns, making this spell more effective than a neutral one as long as your fight is 4 rounds or shorter, and assuming you have boosters, and stronger than Arctic Tornado as long as your fight is 3 rounds or shorter.
Due to the nature of Borrow its value is confusing, and therefore I made a graph illustrating how strong it is based on how many rounds of it have been cast.
Reading the Graph:
Red Line is when compared with a regular level 150 Spell with no lean and no MC.
Blue Line is when compared with Arctic Tornado (Comparison assuming Boosters, otherwise they deal the same damage).
X axis indicates the number of consecutive casts.
Y axis indicates the value percentage of the spell. If that confuses you, Positive Y values indicate "better", negative Y values indicate "worse". (Ex: If X = 1 and Y = 1.5 it means 1 cast of Borrow is worth 0.5 additional casts of the other spell)

Ice
Arctic Tornado (PREMIUM)
Arctic Tornado works the same way as Cysero's Explosive Teleport Booth, and requires you to buy the 12000 Z-Token package. It compresses wind and ice, and seeks between the two.
Location: 12000 Z-Token package

Deploy T.R.E.E. (RARE)
This spell does 6 hits with a *1.5 chance of LS; the best F2P ice spell if you happen to have it.
Location: None

Frigid Fury
Frigid Fury is the best option for those who don't have the above options. The spell consists of 5 equally powerful hits, and has a +6 BTH lean as well as a +4 BTH MC bonus (so +10 BTH in total).
Location: Travel Map -> Travel South -> Varrinsqu Keep -> Elder Saggidus, Cayla's Mirror, Lavai

This spell does 5 hits and takes a -32.5% damage penalty due to being quickcast, but can only be used once per battle.
Location: None

Earth
Creation Burst (PREMIUM)
This spell works the same way as the other Burst spells mentioned here; it deals 50% more base damage than a regular spell, at the cost of a very small amount of HP. It compresses earth and light, and seeks between the two. Like Arctic Tornado and Creation Burst, it requires you to buy the 12000 Z-Token package.
Location: 12000 Z-Token package

Zardzilla Trample (RARE)
The strongest Earth spell outside of the Premium ones, having an inaccurate lean of -5 BTH, and a +5% Damage mastercraft.
Location: None
Info-Subs: Link
Gravity Crush
If you don't have Creation Burst or Zardzilla Trample, then you should use Gravity Crush. It consists of 3 hits, with the first 2 doing 25% damage each, and the 3rd hit doing 50% damage. It has a +6 BTH lean and a +4.25 BTH MC bonus, so it gains 10.25 BTH overall.

Sizzler 'Splosion
A spell that auto-hits (can't be dodged) at the penalty of dealing -30% damage. While it's relatively niche, Wind monsters are some of the dodgiest, and this spell is also useful for farming Shadow Roc (see the Farming Guide).
Location: Warlic Shop -> Mastercraft Sets -> Geocastellum

Energy
Cysero's Explosive Teleport Booth (PREMIUM)
Already mentioned in the water section.
Location: 12000 Z-Token package

Pixel Storm (RARE)
Pixel Storm was part of the 2014 Frostval Giftboxes, and is permanently rare now. If you have it however, then it's the best option available to you below Cysero's Explosive Teleport Booth. It has an 8% chance of dealing 162% damage (coming up to an average of +12.96% Damage) .
Location: None

Truphma Surge
Generally the best spell for pure builds, although, while it deals greater damage than MegaHyperGigaShock, it has a -10 BTH lean so it's widely considered to be inferior on non-pure (250 DEX) builds.
Location: Robina's Shop -> Truphma Saga -> Xov's Fire -> Part 3

Mystic Kaiju Blast (RARE) (TOKEN)
Triggers on enemies with STR, dealing +10% damage against them.

Location: Travel Map -> Travel South -> Varrinsqu Keep -> Kad-Morag, Elder Saggidus

Darkness
Destruction Burst
The top option for Darkness. It compresses both fire and darkness, and it seeks between the two, but not only that, it deals 50% more base damage than a regular spell of the same level at the cost of a small amount of HP.
Location: Dragonspine -> 23: Diamonds and Explosions
Info-Subs: Link
Harm
Archmage Research
Archmage Research is great. When cast, you have 3 options: Summon Mana Spirit, Dissipate Mana and Shape Mana. The Mana Spirit is a strong but situational guest that deals greater damage than normal due to its randomly shifting elements, as well has only attacking half the time. Dissipate Mana is a strong, 1-hit spell that deals Harm damage and damages the monster's MP. Shape Mana works the same way, but it damages the monster's HP instead.

Siphon (RARE)
Can select between three options: an HP drain costing mana, an MP heal that costs nothing, and a greater MP heal that costs 490 SP.
