Fire Emblem Heroes: all you need to know about Ver. 2.10.0 (Abyssal difficulty, Lite Data Version, more)

Another month, another Software update for Fire Emblem Heroes: Ver. 2.10.0! This time around, we have some interesting new features, including a new Abyssal difficulty level for players always looking for a tougher challenge, but also a really handy Lite Data Version for players running low on space on their device. The update will be released early this month.

Here’s a quick rundown of the new features and improvements of Fire Emblem Heroes Ver. 2.10.0:

  • Abyssal difficulty will be added to the Grand Hero Battle rotation
  • Lite Data Version downloads will be added for users who are concerned about space on their devices
  • New Weapon Skills and Weapons to refine will be added
  • A feature for naming favourite marks will be added
  • The help text for some Special Skills will be adjusted

Fire Emblem Heroes Ver. 2.10.0 – Abyssal difficulty

Fire Emblem Heroes Abyssal

Are you finding Grand Hero Battles too easy? Do your Heroes slash their way through Infernal difficulty maps like a hot knife through butter? If yes, you will be glad to learn that the next Software update will add a new difficulty level, called Abyssal.

Unfortunately, the developers do not provide many details about it: all we know is that it will be added to the seven maps that were added to the Daily Grand Hero Battle rotation in February (Zephiel, Camus, Legion, Clarisse, Berkut, Valter, Arvis). Clearing Abyssal maps will allow you to earn gold version of accessories.

Fire Emblem Heroes Ver. 2.10.0 – Lite Data Version

Fire Emblem Heroes was released back in February 2017, and it’s received many updates since then. But as the number of Heroes and maps increased, so did the total data size of the game. It started around 400MB, but it’s now about 1.5GB (depending on your device, and including extra data and cache). While this may not be too much of an issue for players on recent devices, with large amount of internal memory, it certainly is for many users who don’t have much space left on their (aging) device.

That’s why the developers are introducing a really handy feature in Fire Emblem Heroes Ver. 2.10.0: Lite Data Version. As the name implies, it allows you to download a “Lite” version of the game, that takes less storage space on your device. Of course, the developers did not resort to black magic to lower the file size: they simply lowered the quality of the graphics and sound.

While this may seem like an extreme move, it was certainly effective: according to them, this reduced the file size by about 75% (results may vary depending on your device). The screencap below shows the HQ version at 1 224.6MB, and the Lite Data Version at 277.7MB… that’s quite the difference!

The good news is that you will not have to download a new version of the game: you can simply switch between the Lite Data Version and the HQ version right from the Miscellaneous menu (by selecting the Change Data Quality option).

If you haven’t started playing yet, you will be able to select the Lite Data Version right at the start: you will not have to download the entire thing first, which may be impossible for you if you’re already running low on space. If you have already started playing, you will also be able to select the quality of game data by deleting game data using Clear Cache on the title menu.

Fire Emblem Heroes Ver. 2.10.0 – Weapon Refinery Update

Fire Emblem Heroes Weapon

What would an update for Fire Emblem Heroes be without a Weapon Refinery Update? Ver. 2.10.0 will introduce one new Weapon Skill, as well as more Weapons to refine.

Let’s start with the new Weapon Skill:

  • Solitary Blade (Lon’qu: Solitary Blade). Can be upgraded in the Weapon Refinery once obtained.

And here’s the Weapons to refine:

  • Vidofnir (Tana: Winged Princess)
  • Nidhogg (Innes: Regal Tactician)

Fire Emblem Heroes Ver. 2.10.0 – Favourite-mark names

Finally, we have one last feature for Fire Emblem Heroes Ver. 2.10.0: the ability to give a name to the favourite marks! To change the name, select “Edit Favorite Name” below “Sort by Number” on the screen where favorite order display is set.

Fire Emblem Heroes Ver. 2.10.0 – Special Skills

One last minute change not mentioned in the initial notification: the help text for some Special Skills has been modified. Here’s the list of Special Skills affected by this change:

  • Retribution
  • Reprisal
  • Vengeance
  • Dragon Gaze
  • Draconic Aura
  • Dragon Fang
  • Glowing Ember
  • Bonfire
  • Ignis
  • Chilling Wind
  • Iceberge
  • Glacies
  • Regnal Astra
  • Fire Emblem

Here’s the changes that were made:

The damage done to enemies in battle is calculated as described below.

■ Step 1: The Base Damage value is calculated.
Base Damage = (Atk × advantage bonus × effectiveness bonus) + damage boosts from Special-skill effects – foe’s Def (or Res) – defensive-terrain effects (see Note 1)

Note 1: If the total would be 0 or less, Base Damage is treated as 0.

■ Step 2: The Adjusted Damage value is calculated.
Adjusted Damage = (Base Damage + damage dealt from non-Special skill effects [see Note 2]) × 1/2, if weapon is a staff(see Note 3), × damage-reducing skill effects (see Note 4) (see Note 5)
Note 2:Wo Dao, Shining Bow, Wrath, etc., for example.
Note 3:If the result is not a whole number, the result will be rounded down.
Note 4:Pavise, Ice Mirror, Divine Tyrfing, Urvan, etc., for example.
Note 5:If the result is not a whole number, the result will be rounded up.

■ 3. The Final Damage value is calculated and dealt to the foe.
Final Damage = Adjusted Damage – skill effects that reduce damage by a fixed value (see Note 6)
Note 6: Shield Pulse, etc.

Skills whose effects occur in Step 1 are now phrased as boosts damage and skills whose effects occur in Step 2 are now phrased as deals damage in order to clarify how damage is calculated.

Do note that the amount of damage has not been modified since Ver. 2.9.1!

And that’s it for Fire Emblem Heroes Ver. 2.10.0! As usual, the official patch notes will be added to this page once available. Don’t forget to keep an eye out on the Events and Content Updates and Characters pages to keep up to date with all that’s happening in Fire Emblem Heroes!
