Hello everyone and welcome to my 242st analysis, this time featuring Nitroblaster.
Overview: Say hello to one of the deadliest attackers in the game. Nitroblaster's damage output is truly ridiculous, possessing moves with high Base Powers and an amazing Base Strength that's the second highest among viable monsters at the time of writing. Artifact is a double edged sword that blocks all kinds of debuffs like Tortures, deny effects and Precision modifiers and also buffs like damage boost, but Nitroblaster doesn't feel this too much since he's loaded with great damage from the get go, allowing him to mow through teams without worrying about debuffs. Artifact is further complemented by his Relics, more specifically Armor, granting him protection against direct damage, which becomes the only way to bring Nitroblaster down. As he ranks up, Nitroblaster becomes able to fill other roles too, making him a flexible monster that can easily find a room on almost any team.

Builds:
Monsters that have access to Group 4 skills will have a slightly different build path. I will list the most viable builds for each Rank since some moves in Group 4 are pivotal to some sets' success. The monster's role will likely remain the same, however, so this won't be exhaustingly long as I won't repeat the same things.

Rank 0:
Moves:
-Beam Of Inferno
-Look At The Core
-Core Exposure
-You And Your Friends/Burning Beam/Ignition Beam
Runes: 2 Strength 1 Speed/3 Strength
Mutant Rune options: Strength&Life, Speed&Life
Relics: Amulets and Armors

Build Explanation:
Beam Of Inferno is Nitroblaster's best AOE at this point, having a solid 40 Base Power and applying both Burn and Ignite to all enemies, which stacks up damage really fast. Look At The Core has a great 60 Base Power, is unresisted, and adds Sunburn to the equation of Tortures, furthering the Life drain. Core Exposure helps in extending damage against opponents in case you are planning on using raw damage to kill an enemy - this is particularly useful when there's an enemy on the team you want to kill and Tortures can manage this, but the enemy team has a buffer to remove them. It can also be used to apply all of your Tortures to one enemy by following it up with Beam Of Inferno. In the last slot, You And Your Friends offers the greatest single target damage Nitroblaster has without factoring in Tortures, and it also deals some damage to the other enemies which is appreciated, and can be combined with Core Exposure to greatly harm two enemies - this should definitely be used if there are no Dodge Area monsters on the enemy team. Burning Beam's single target damage is very great when you keep in mind the Tortures it applies, and it can be used if you want to nail Dodge Area monsters since they will take little damage from You And Your Friends, and will dodge the Sunburn of Look At The Core. Another option in the last slot is Ignition Beam, which is very similar to Burning Beam but it trades the Burn for 0 CD, making it a valid choice against teams with CD Activation.
2 Strength 1 Speed with Life Mutations is a standard on attackers. 3 Strength is also notable since it provides Nitroblaster with so much damage that he can easily one shot targets without Life Runes.

Rank 1: Nitroblaster learns "Support The Organics" at this level, a move that gives all allies Double Damage, and Nitroblaster an extra turn. His trait also evolves to gain Water Protection.
This move is not worth it at this point, so skip it. The Water Protection is not the best, but it's nonetheless appreciated since it makes him have no weaknesses.

Rank 2: Nitroblaster learns "Star Kore" at this level, a Base 60 Fire move that gives its target Burn and Ignition, and Nitroblaster an extra turn.
(High Firepower)
Moves:
-Star Kore
-Beam Of Inferno
-You And Your Friends
-Core Exposure
Runes and Mutant Runes are the same as given above.

Build Explanation:
Star Kore is an immensely powerful attack that not only deals hefty damage with its 60 Base Power and added Burn + Ignition, but it also gives Nitroblaster an extra turn, so he can continue dealing damage in a short period of time. You And Your Friends goes well together with Star Kore and Core Exposure to quickly bring down 2 enemies, so it's used over Look At The Core.

(Extra Turn Spammer)
Moves:
-Star Kore
-Support The Organics
-Core Exposure
-Dehydration
Runes: 1 Stamina 1 Speed 1 Strength/2 Stamina 1 Speed
Mutant Rune options: Stamina&Strength, Speed&Stamina, Strength&Stamina

Build Explanation:
At this Rank, Nitroblaster gains the ability to keep on using his extra turn moves alternatively, so he can become an extra turn spammer. The main big hitter on this set is Dehydration followed by Star Kore on the same target, which results in very great amounts of damage when also factoring in the Tortures. Support The Organics' Double Damage on his team is also good to power up your more supportive monster so that they deal some damage, in case you fail to wipe the enemy out. With Core Exposure + Star Kore, Nitroblaster can apply Burn, Sunburn and Ignite to a single target, which siphons Life extremely fast.
1 Stamina 1 Speed 1 Strength is an extra turn spammer's standard spread, with Stamina or Strength Mutations wherever possible. 2 Stamina 1 Speed is also plausible, since it allows Nitroblaster to spread Tortures way more effectively.
This spread will not be mentioned again since it will not change across further Ranks.

Rank 3: Nitroblaster learns "Evaporation" at this level, a Base 50 Fire AOE that applies Fire Weakness to all enemies. His trait also evolves to include a SC that gives your team Damage Boost.
Beam Of Inferno will do greater damage most of the time, and Fire Weakness is not good enough to consider it over said move's Tortures. Skip this.
Regarding his SC, it will not be applied to Nitroblaster since Artifact blocks buffs, so keep that in mind.

Rank 4: Nitroblaster learns "The Posthuman" at this level, a move that removes Nitroblaster's Trait, gives him Pierce and Positive Effect Protection, and activates all CDs on its target.
(High Firepower)
Moves:
-Star Kore
-Beam Of Inferno
-The Posthuman
-Core Exposure/You And Your Friends
Runes and Mutant Runes are the same as given above.

Build Explanation:
The Posthuman is a high risk, high reward move. It will activate the CDs of any monster you want on the enemy team regardless of Mega Taunts or Mirrors (Evasion and CD Protection will still block it though), and he will keep Pierce most of the time thanks to the Positive Effect Protection, but it also disables his Trait to give himself these buffs, so be wary. Core Exposure will most likely be in the last slot in this set, since You And Your Friends offers too little in terms of utility when compared to his other moves.

(Support)
Moves:
-Beam Of Inferno
-The Posthuman
-Support The Organics
-Star Kore/Core Exposure/Look At The Core
Runes: Explained below

Build Explanation:
This is probably something you would not expect this monster to do, and to be fair, it's not very clear the first time you look at him. But, the amount of Tortures under Nitroblaster's belt, Artifact providing protection against Tortures to allow for survivability, The Posthuman's utility + deny factor and his absurd damage boosts can be combined to make this Nitroblaster a very good ally to attackers or a glue to a team that can't find a last member. The idea is to use Support The Organics followed by any move of your choice to give your two allies Triple Damage without losing any momentum, something very few supports, let alone monsters, in the game can achieve. The last slot should be decided based on the enemy team and personal preference; Star Kore is the choice most of the time since it allows you to apply great Torture pressure on an enemy without losing momentum and also deals good damage initially on its own, but Core Exposure can be followed up by Beam Of Inferno to apply 3 Tortures to an enemy in a single turn, which is something a support appreciates, plus Sunburn can cause the enemy to miss attacks. If losing momentum is not a problem and you like Sunburn a lot, Look At The Core can be followed up by Beam Of Inferno over two turns to apply three Tortures to all enemies, chipping away at Life extremely fast.
For the Runes, you have to use a spread that outspeeds your attacker, and fill the rest with Team Speed. For example, if you have a 1 Speed 2 Strength Wyrmlad on your team, use 2 Team Speed 1 Speed on Nitroblaster, or use 3 Team Speed on it if the Wyrmlad has 3 Strength - this works because Wyrmlad's Base Speed is lower than Nitroblaster's. On the other hand, if the attacker has a higher Base Speed, like Makugan, you need to use 1 more Speed Rune than they do - a 2 Strength 1 Speed Makugan needs a 2 Speed 1 Team Speed Nitroblaster alongside her. The reason why Nitroblaster needs to outspeed your own attacker is because we want the attacker to start their turn with Triple Damage, and hopefully wipe out the enemy in a single shot, especially when combined with Nitroblaster's own attack.

Teammate Options: Since Nitroblaster has lots of Tortures, allies to apply more diverse ones, like O'Reilly or Zeighar make good partners to quickly eat through the enemy team. Attacker Nitroblaster doesn't have unique interactions until Rank 4 since Artifact blocks any and all buffs, but turn transfers can still be used and you can still fill up his Stamina. After you use The Posthuman, you can have an ally increase your damage or give you Evasion, and they will be protected by the Positive Effect Protection. For the Support set, you obviously need an attacker to get the full value from it. For more Teammate options, check out this article.

Countering Nitroblaster: The best way to do this is to activate his CDs or drain his Stamina, since for the former he can never have protection for it due to Artifact, and for the latter Artifact doesn't block it. Trait Disable leaves him vulnerable to debuffs, but be careful as he may get buffs from his allies thanks to it. He also uses extra turn moves, so an Anticipation monster can halt him while he's doing that. For more Counter options, check out this article.
