Surprise, surprise, the once neglected Earth element is now your primary element and it's about time for our stalwart Terremotus to get his fair share of the spotlight! With Elemental Spirits now as your main weapon for endgame, most of your modifiers will be funneled towards Earth and Water elements. This is even further backed up when you pair Ilse El Heine Card with Yorscalp Crown of Judgment . This combo will give you 75% Terra Drive and Lightning Land modifiers when both your Yorscalp Crown and Elemental Spirits are refined to +15, and then on top of that you can capitalize on the 100% Earth/Water element magical property bonuses from [MVP] Polluted Queen Spider Card (27362) .
Due to the insane amounts of skill modifiers that you will reap off of the Episode 21 card Ilse El Heine and Yorscalp Crown combo, this gives Terremotus a sharper edge than Diluvio even though both of them will benefit from other sources of damage modifiers.
In a party composition where you will benefit from all kinds of buffs, Earth proves to be the strongest element to choose from. The Arch Mage class will act as a dedicated debuffer via their skill Level 4 Climax + Violent Quake (Climax Earth) to reduce the affected enemies' Earth resistance by 100%. Water element doesn't get such debuffs from the Arch Mage, but Fire will get some via Level 4 Climax + All Bloom (Climax Bloom), which will reduce the opponents' Fire element resistance by 100%. Combine all these debuffs with your own elemental insignias and you will for sure shine the brightest among all the magical classes in your party.
Apart from increasing the base MAtk% of your Terra Drive skill, Terremotus will also grant you the ability to endow your Elemental Buster to the Earth element. Both skills are burst type and their main purpose is to either delete monsters in a single cast or melt them fast enough to end the fight immediately. Elemental Spirits gives you the ability for both skills to coexist at the same time via autocasting, so I would advise you to utilize this advantage.
One of the best areas where Terremotus is ideally used is in the endgame dungeon Zero Cell Sector (Nox & Ark). Granted the monsters M.GN-6059, M.GN-0001 and their partner homunculus are Fire and Earth element and thus resists and are immune against Earth—respectively, Earth-endowed Elemental Buster will hit all the mobs here. Nox Floor mobs are also generally less tanky than Ark Floor's and they will die instantly with your Double Busters when you're endgame geared.
Diluvio also gets a glow up alongside Terremotus because she also benefits from Elemental Spirits 's autocast shenanigan. Every time you cast Diamond Storm, you will autocast Elemental Buster, and when you use the card [MVP] Polluted Queen Spider Card (27362) you will get 100% Earth/Water element magical property bonuses. As had been previously mentioned, the two primary reasons why Diluvio ranked 2nd and below Terremotus is because Diamond Storm won't get any skill modifiers from Ilse El Heine Card + Yorscalp Crown of Judgment , and Water won't get any less 100% resistance from Arch Mage's debuffs. However, Arch Mage can give you 30%Water property elemental modifier with their skill Level 1 Climax + Crystal Impact, but with the enormous amount of elemental modifier you will have and due to the so-called diminishing returns, the added bonuses won't be as impactful as compared to when elemental resistance is reduced by 100%.
Water gets access to one of your elemental floor buffs via Deluge, and this skill boosts any Water property elemental attacks by 20% including your Diamond Storm and Water-endowed Elemental Buster. The damage boost you get from Deluge will make it on par with Earth's Ilse El Heine and Yorscalp Crown combo. One of the key reasons why both Earth and Water builds are comparable to one another for solo-play, but differ greatly once placed in a party scenario.
Diluvio will retain all of its utility including endowing your armor to the Water property to give you 100% resistance against Water-based attacks via Level 2 Elemental Control (Defensive Mode). This will make you survive Encroached Tan's Jack Frost and Ghost Ship Captain's Water Ball. Even with no access to [MVP] Golden Thief Bug Card (4128) , you can easily cheese your way and make instance farming effortless.
Serpens for the most part is only really used for Varmundt's Biosphere Depth 2 and Forgotten Time. Nothing much has changed for Serpens with the addition of Elemental Spirits . Despite losing some Poison property modifiers from Time Dimensions combo, that was compensated with the ability to double cast your Elemental Buster without ever needing to switch books. It just made your farming speed faster for these two dungeons honestly. And if you worry too much about the loss of Poison property modifier, you can always find a good distribution of Poison magical enchants on your Encroached Book [2] (540109) first before reforming it to Elemental Spirits.
In Depth 2 and Forgotten Time, all the mobs, with the exception of the Valkyrie and the Contaminated Spirits, are made up of Fire, Water, Wind, and Earth properties and if you still remember from the previous section we've talked about—Poison is strong against the four (4) basic elements. Levels 1 & 2 monsters of these elements take 150% damage against Poison while Levels 3 & 4 mobs receive 125% damage. Serpens is perfect for these two dungeons.
Serpens outside of Depth 2 and Forgotten Time is not technically bad; you may still use him but there are just better High Elementals for those areas. Poison element is also mostly for coverage where it's there to hit the mobs that the four (4) basic elements resist.
When using Serpens, avoid using Lvl. 2 Elemental Control (Defensive Mode). While Poison element is strong offensively against Fire, Water, Wind, and Earth, it is also weak against them defensively; if you endow your armor to Poison 1, you'll receive 150% damage. Better to just leave him in Passive Mode or Waiting Mode.
Ardor has still retained its strengths and utilities and don't ever think he is no longer a powerful spirit to use. I would say he just got outranked by both Terremotus and Diluvio due to the distribution of skill and elemental modifiers, but he did not necessarily lost his viability.
There will be places where Ardor is still the most preferred High Elemental to summon. Places like Varmundt's Biosphere (Grass, Death, & Venom) and Ruined Valkyrie Realm where Fire will hit the hardest or has far greater coverage, you will for sure need the assistance of our beloved Ardor.
Ardor's ability to endow your armor to the Fire element by activating Defensive Mode with the skill Level 2 Elemental Control makes him the best spirit to use for The Immortal and Recreated Dark Whisper instances. You will survive Lasgand and Immortal Monarch's Meteor Storms and resist their Heaven's Drive skill; likewise, if you use Ardor for Mjolnir Underground Cave, you will survive the Aferdes that cast hard hitting Fire magical spells and some random Ignition Break here and there.
Ventus will always going to make it to the list no matter what despite her being an Elemental because it is simply necessary and I just can't help it but include our baby Ventus!
We're already in 4th jobs era and Ventus is still our best friend and our close confidant for everywhere else we go~ Whether we need to have Guyak she'll give it to us for free with the help of her Wind Step skill. Now you can casually farm Eden Coin (25223) at Second Power Plant and when you don't want to be late for events she'll make your move faster than the speed of light!
Baby Ventus with her Adolescent and Adult Forms can also provide easy access to 1 second FCT reduction when Lvl. 1 Elemental Control (Passive Mode) is activated which helps newbies early on in their journey.
Just be wary because once you use Ventus or any of the Sorcerer Elementals you won't be able to use or autocast your 4th skill Elemental Buster since this skill requires you to have your High Elementals present to activate.
Lil' Ms. Aqua is sometimes used in PvP scenarios like WoE and Battlegrounds (BG) where she's sought after because of her ability to increase Diamond Dust's crystallization's chance of effect by (JobLv ÷ 5)%.
Everybody knows how annoying the crystallization debuff can be when it's applied. You will be rendered susceptible to a couple of attacks, increasing the damage you take by 50% from Wind property magical attacks and several weapon types such as Maces, Axes, and Two-Handed Axes; not to mention you cannot move, attack, and use most of your skills and items. Truly, Aqua may look cute and innocent on the outside but she is as deadly as a viper!
