Note: This guide is being made off of the information found with the writers experience of getting each achievement, and any patch notes that can currently be found on the rivals website if any information is incorrect, out of date, etc. please feel free to link a source that would show the correct information and I will update the guide as soon as possible.

All tutorial and practice modes can be found in the local -> solo mode menu options.

The Apprentice Rival



This achievement is awarded to those who simply complete all of the beginner tutorials. Simply follow the tutorials instructions and it is awarded.

The Master Rival



This is a slight bit more difficult than the begginer rival, but the concept is the same, complete all of the tutorial lessons.
note: as I have had this completed for a long time, I am not currently aware if the character specific tutorials are required for this.

The Sceptical Rival



Possibly the easiest achievement to get, you simply go through the menu options local -> solo -> practice mode. Start a practice match pause, turn on the option for visable hitboxes, and unpause.

The story mode can be found in Local -> solo modes -> Story mode

All of the basic story mode achievements:
A Fiery Tale



A Rocky Start



A Slippery Saga



A Smoldering Plot



An Adverse Adventure



A Maypul Story



Can be gained by simply completing each of the character story modes.


However the:
Open the gates



Cannot be completed untill all of the character specific story modes have been completed.

You are not required a minimum rank for any of these achievements, you simply need to beat them.

The Lone Rival



This Achievement requires you defeat the "Epilogue" of the story mode (the story part that is unlocked after all of the character specific modes have been completed) Without loosing a stock.

The best method of doing so is playing the character you are most confident with, parrying as many of the attacks of the boss itself as possible, and knocking any minions it spawns into the boss's eyes to stun that eye for essentially free damage.


The Swift Rival



This achievement has been widely known as one of the most difficult achievements for the story mode, as it requires you to get a gold time for each of the characters story modes and the epilogue.
In order to get a gold metal for a story mode you simply need to complete it in under 2 minutes.
Meaning that you need to be able to take 1 stock within 20 seconds.

Edit: I can't currently directly confirm this myself, but according to multiple sources the required time for how long you have to 'speedrun' each possible level to get this achievement has been extended and made considerably more forgiving since the creation of this guide.

You best bet is to try and recreate speedrun videos of each of the story modes.
Wrastor: https://www.youtube.com/watch?v=TO_N64YhQ1M
Forsburn: https://www.youtube.com/watch?v=RgLXAV9HNi8
Maypul: https://www.youtube.com/watch?v=WXQzM2h7dN4

Zetterburn: https://www.youtube.com/watch?v=FFkO1pe1-v4
Krag: https://www.youtube.com/watch?v=Ykr63cCzAe0

Here are some example videos.
However if you are simply attempting to get the achievement, several of these do require some higher skill techs and such so I suggest only attempting to recreate the parts of the speedruns that you feel you are capable of, to shave off seconds of time. As so long as the over all story mode takes less than two minutes the times of the individual levels do not matter.

Unlocking this achievement will unlock the secondary custom color set for the player in question.

All of the following achievements can be recieved while fighting both bots and human players.
The Watery Trap


This achievement requires you get a kill using orcanes up special recovery.

The easiest method of doing so is damaging an opponent to a high kill % and preforming the up special while they are overtop of your puddle. This can be done with an inactive human player if you dont want to deal with the bot's random DI.

The Boulder Barrage



This achievement requires a kill by the pebbles that krags rock splits into after being hit.

The easiest method of getting this is smacking a bot far off of the stage and hitting an already spawned rock, to send the pebbles in the opponents direction to finish the kill. It is suggested to preform this against active players or bots, as the required kill % for on stage pebbles is rather high.

The Calculated Strike



This achievement requires a killing blow with the extended hitbox of absa's down air when it sweet spots her cloud.
The easiest method of preforming this is forcing your opponent to recover low and close to the stage, having your cloud just of ledge and sweetspotting a down air out of a short hop.
It is suggested to preform this against players or bots as it is easiest to preform while the opponent is attempting to recover.

The Deadly Deception



The requirements of this achievement is to get a kill using forsburns clone ability.
The more consistant method of doing so is allowing the explosion of the clone when preforming down special while the clone is out and off stage with the opponent.
Like absa's achievement it is easier to preform on bots and humans as it requires positioning that is difficult to achieve while controlling two characters at once.

The Icey Plummet



This achievement requires you preform a spiking (fast downward knockback) kill with etalus's recovery up special.
The easiest method is the same as absa's, force the opponent to recover close to the stage and preform the move when they get to a good position for it.
Also like absa's it is suggested to do against active players and bots as it can require active recovery to be preformed.

The Reckless Flame



This achievement requires a killing blow with the air varient of zetterburns down special.
This move travels and hits downward, so hitting an offstage opponent is the easiest method of gaining this achievement.

The Terrible Tempest



This achievement requires a killing blow off of the top of the stage with wrastors tornado neutral special.
The easiest method of preforming this is simply comboing the opponent up high and catching them in a rising tornado by holding your special button.
This achievement can be recieved while using inacive players as it does not require any movement of the second player.

The Vicious Vine

The requirement of this achievment is getting a kill with an air move after preforming the held down varient of maypuls up special recovery.
The easiest method of getting this is either preforming the recovery to an airborn opponent and using up or forward air (depending on position) to knock them out, or preforming it to a hard hitting air move while in high kill %.

You can find the abyss mode in Local -> solo -> abyss -> abyss endless.

Into The Depths



Simply play the endless abyss mode for a minimum of 15 waves.

To make this easier, simply play the character you are the best in 1 vs a group senarios in.

The Endless Abyss



The same concept as "Into the depths" except you need to get to a minimum of wave 45.

The best method is choosing a character you are good with, having them leveled up to at least level 9, and having a good set of runes equipped to maximize your chance of survival to that point.

By this time you should have hit waves that you can buy your way to, so if need be you can spend the in game currency to skip the earlier waves and as such the damage from said earlier waves.

The Ardent Rival



To gain this achievement you need to get all of the currently available abyss characters to level ten. (at the time of this being written that is only the characters that come with the game, no dlc characters are required.)

There are several methods to make the process faster.
You can preform a selection over site to have 4 players at once (increasing the difficulty but spawning 4 times the xp crystals.)
Better explained in this video: https://www.youtube.com/watch?v=OGh_jRrvOR0

A slightly easier version of the above using the keyboard to select a second player, if you have a controller, or vice versa if youre more comfortable with the keyboard controls. (which increases the difficulty slightly for 2x the crystals, while being able to move the inactive player as needbe)

Or, the way properly intended by the developers, buying your way to higher waves, as each of the higher waves have higher experience yeilds.

If you wish to combine some of these methods, you are able to further increase the amount of xp gained but the instances will be considerably more difficult.

This achievement will unlock the map that the abyss mode is played on for regular non-online mode vs battles.(though if you have played online you will know you can play that map without getting the achievement)

The Seasoned Rival



To gain this achievement you simply need to play a minimum of 300 games in either the local match mode (both against humans and bots) and or in any of the online vs modes.

The easier way of doing this is simply making the matches 1 stock against a really easy bot. It is advized against however as it is commonly more enjoyable to play properly challanging matches. (however if this method of grinding matches is your cup of tea then go ahead).

The Opulent Rival



To get this achievement you simply need to earn a total of 100,000 of the in game currency that is dropped after you finish: a vs battle (local or otherwise), or abyss run.

The fastest way of getting to the high amount of coins is winning money matches. Loosing coins or spending the coins in the abyss mode do not effect the total number you have accumulated as far as the writer knows.

Rivals of aether is an amazing game, After completing all of the achievements I can say, despite there being plenty of angering moment, that it feels good to have done each of the achievements.

I hope this guide can be of some use to achievement hunters that are just picking up the game.

Best of luck to all of you, and may your match wins be plentiful.
