Pokemon Legends Z-A: The Ultimate Techniques Guide

By newsgame

Side Mission 186: The Ultimate Techniques in Pokemon Legends: Z-A Mega Dimension tasks players with fighting in three trials where the odds are heavily stacked against them. In each trial, players can only use one of the Legends Z-A starters’ final evolution forms: Meganium, Emboar, and Feraligatr to beat three fully-evolved Pokemon of the opposing type in a back-to-back battle.

It’s one against three in every trial, and not only are the opposing Pokemon nearly max level, but they have the type advantage as well. This guide covers the battle strategy and best builds for each trial, as well as a rundown of how to secure the win easily.

Best Fire-Type Pokemon in Pokemon Legends Z-A (& Where to Find Them)

From Charizard to Emboar, here are the best Fire-type Pokemon to use in Pokemon Legends: Z-A.

How to Start The Ultimate Techniques

How to Unlock: Side Mission 186 The Ultimate Techniques becomes available in Hyperspace Mission 12: The Greatest Gift, after players visit the Rust Syndicate.

Talk to Arcannes near Cafe Bataille inside Wild Zone 6 to start The Ultimate Techniques side mission. She will offer players three trials: The Trial of Grass, the Trial of Fire, and the Trial of Water.

To start a trial, deposit all Pokemon in your party in the Box except the one that has to go through the trial. The Trial of Grass requires Meganium, the Trial of Fire requires Emboar, and the Trial of Water requires Feraligatr.

The Trial of Grass (Meganium)

Meganium Build
Meganium Level 100 Held Item: Meganiumite Nature: Modest	Light Screen	Learns move at level 50.
	Synthesis	Learns move at level 40.
	Ancient Power	TM 120 Ancient Power can be purchased for 360 Mega Shards from Secret TM Vendor.
	Earth Power	TM 52 Earth Power can be found on the rooftop in Juane Sector 7, just south of Wild Zone 15. Can only be accessed after completing Side Mission 80: A Shocking Territorial Dispute (unlocks after reaching Rank C) to unlock the Holovator nearby.

Mega Evolve as soon as the battle starts, and then set up the Light Screen immediately. Light Screen doubles Meganium’s Special Defense, halving the amount of damage any special moves will do when targeted at the Pokemon. Both Charizard and Delphox are special attackers, and Blaziken is a mixed attacker, which means Light Screen will get a lot of value here.

Mega Meganium is still weak to Fire-type moves, which means you will need to rely on healing items like Max Potion and Full Restore to heal yourself mid-fight. If the bag is on cooldown when you fall to low health, use Synthesis, and you should be able to secure a win.

The Trial of Grass Pokemon	How to Beat
Charizard	Ancient Power should make quick work of Charizard thanks to its 4x weakness to Rock-type moves. Earth Power is ineffective because Charizard is Flying-type.
Blaziken	Rely on Earth Power to deal massive damage, then follow it up with Ancient Power if the Pokemon is still standing.
Delphox	Both Earth Power and Ancient Power are super effective against Delphox.

How to Beat

Charizard

Ancient Power should make quick work of Charizard thanks to its 4x weakness to Rock-type moves. Earth Power is ineffective because Charizard is Flying-type.

Blaziken

Rely on Earth Power to deal massive damage, then follow it up with Ancient Power if the Pokemon is still standing.

Delphox

Both Earth Power and Ancient Power are super effective against Delphox.

For successfully defeating Charizard, Blaziken, and Delphox with your Meganium in the Trial of Grass, you’ll receive TM 160 Frenzy Plant.

The Trial of Fire (Emboar)

Emboar Build
Emboar Level 100 Held Item: Emboarite Nature: Adamant	Solar Blade	TM 152 Solar Blade can be purchased for 540 Mega Shards from Secret TM Vendor.
	Trailblaze	TM 115 Trailblaze can be purchased for 360 Mega Shards from Secret TM Vendor.
	Drain Punch	TM 131 Drain Punch can be purchased for 420 Mega Shards from Secret TM Vendor.
	Thunder Punch	TM 23 Thunder Punch is a reward for reaching Level 15 in Mable’s Research.

Mega Emboar is a beastly physical attacker, and in order to easily take out the Water-type Pokemon facing it in this trial, the stat boost from the mega evolution is essential. Since Emboar has access to a lot of super-effective moves against Water-types like Thunder Punch and Solar Blade, this trial is all about offense.

Solar Blade is nominally the most powerful move in Emboar’s arsenal, and all three Pokemon in the trial are weak to it. However, due to the long wind-up animation attached to this move, it may not end up working out as expected. Trailblaze is there as a safety net to take advantage of any Grass-type weaknesses the enemies may have.

The Trial of Fire Pokemon	How to Beat
Blastoise	Solar Blade, Trailblaze, and Thunder Punch are all 2x effective against Blastoise.
Swampert	Solar Blade should be able to easily OHKO Swampert due to its debilitating Grass-type weakness. Follow it up with Trailblaze if it somehow survives.
Greninja	Use Drain Punch to recover health and deal massive STAB damage, then use Thunder Punch or Trailblaze to take out Greninja if it still remains standing.

How to Beat

Blastoise

Solar Blade, Trailblaze, and Thunder Punch are all 2x effective against Blastoise.

Swampert

Solar Blade should be able to easily OHKO Swampert due to its debilitating Grass-type weakness. Follow it up with Trailblaze if it somehow survives.

Greninja

Use Drain Punch to recover health and deal massive STAB damage, then use Thunder Punch or Trailblaze to take out Greninja if it still remains standing.

For successfully defeating Blastoise, Swampert, and Greninja with your Emboar in the Trial of Fire, you’ll receive TM 158 Blast Burn.

The Trial of Water (Feraligatr)

Feraligatr Build
Feraligatr Level 100 Held Item: Feraligite Nature: Adamant	Ice Fang	TM 15 Ice Fang is a reward for reaching Level 7 in Mable’s Research.
	Icicle Spear	TM 149 Icicle Spear can be purchased for 420 Mega Shards from Secret TM Vendor.
	Protect	TM 17 Protect is a reward for reaching Level 4 in Mable’s Research.
	Breaking Swipe	Learns move at level 26

The Trial of Water is actually the easiest among all the trials because Feraligatr has an easy way of dealing with its weakness: Mega Evolution. Mega Feraligatr becomes a Water/Dragon-type Pokemon, canceling out its 2x weakness to Grass-type moves. Water/Dragon is one of the better defensive typings in Pokemon, and Mega Feraligatr is only weak to Dragon and Fairy-type moves.

All three Pokemon in this trial are weak to Ice-type moves, which makes Ice Fang and Icicle Spear the best offensive type moves for this match. Protect can be used in case things don’t go according to plan, whereas Breaking Swipe is here as a fast, STAB move to chip down the last remaining health of any Pokemon unwilling to go down.

The Trial of Water Pokemon	How to Beat
Venusaur	Use Ice Fang, followed by Icicle Spear. If it remains alive, Breaking Swipe. Protect if it still doesn’t go down.
Sceptile	Use Ice Fang, followed by Icicle Spear.
Chesnaught	Use Ice Fang, followed by Icicle Spear.
