(Live Now!) Hearthstone 27.0.3 Patch Notes – Solid Alibi & Lab Constructor Nerfs

Update: The patch is now live!

27.0.3 – a small nerf patch – was teased yesterday. We knew two cards that are getting hit, but we didn’t know what those changes will be yet. Blizzard just posted full patch notes – no surprises there to be honest, the nerfs are very straightforward and most of the players have predicted them.

On top of that, Mechwarper was banned from deck building in Duels and a few bugs were fixed.

The patch is data only so it should be out on both PC and mobile at the same time. It will roll out today (we don’t have the exact time yet).

Check out full patch notes below:

Patch 27.0.3 is a data-only patch, rolling out today, with the following updates and bug fixes.

Hearthstone Updates

Dev Comment: This is a smaller, numbers-only adjustment intended to address negative play experience outliers from the first few days of the new expansion. There will be another patch a couple weeks after this one where we will have more data points to make larger adjustments to the meta, if needed.

Solid Alibi

  • Old: [2 Mana]
  • New: [3 Mana]

Lab Constructor

  • Old: [4 Mana]
  • New: [5 Mana]

The above cards will be eligible for a full dust refund for two weeks following Patch 27.0.3.

Duels Update

  • Mechwarper has been banned from deckbuilding and all card pools.

Bug Fixes and Game Improvements

  • [Hearthstone] Updated Sparkbots to better match their colors to their effects. WARNING: Wear proper safety equipment and read card texts to mitigate the risk of misplays while handling Sparkbots.
  • [Hearthstone] Fixed a bug where Dormant Titans could activate their abilities (kind of), causing issues.
  • [Hearthstone] Fixed a bug where the Korean language version of the Forge tooltip displayed incorrectly.
  • [Hearthstone] Fixed miscellaneous localization issues across languages.
  • [Duels] Fixed a bug where Open the Doorways didn’t trigger off of Symphony of Sins or Snack
  • [Collection] Fixed a bug where the Sargeras card back appeared as unowned and couldn’t be favorited.

    “adjustment intended to address negative play experience”, maybe for the mech one mana more can make the difference in a aggro deck, but for solid alibi the negative experience don’t change for one more mana.
    The card should be treat like 3 rune spell of DK and never discover/replayable in any way and change the card like Cariel hero (only half damage taken) then you can talk.
