Hearthstone September 28 Hotfix is Patch 36.6.2, a server side update focused on four specific problems rather than a large balance pass. Blizzard fixed conditional Battlecry minions that could become unplayable without a valid target, Riff cards failing to replay the previous Riff on Finale, Galactic Projection Orb using modified spell costs and a Book of Faelin puzzle state that could end in a tie.
Because Hearthstone September 28 Hotfix is server side, players do not need to treat it like a normal client download with a large patch package. The fixes are rolling out through the live service, while Blizzard is already pointing ahead to Patch 36.6.3 for more substantial Battlegrounds balance work.
Everything fixed in the Hearthstone September 28 Hotfix
Hearthstone September 28 Hotfix addresses four gameplay bugs. Conditional Battlecry minions should once again be playable when there is no valid target, Riff Finale effects should correctly replay the previous Riff, Galactic Projection Orb now checks original spell cost instead of modified cost, and the Book of Faelin Dredge issue should no longer force a tie after certain puzzle resets.
The list is short enough that it is worth checking your exact problem against it. Hearthstone September 28 Hotfix is not a general stability patch that claims to solve every current bug, so an unrelated disconnect, visual problem or Battlegrounds balance complaint needs a different fix or a later update.
| Issue | Fix |
|---|---|
| Conditional Battlecries | Playable without a valid target where intended |
| Riff Finale | Replays the previous Riff correctly |
| Galactic Projection Orb | Uses original spell cost |
| Book of Faelin Dredge | No longer causes the affected puzzle tie |
Galactic Projection Orb now uses original cost
The most mechanically important Hearthstone September 28 Hotfix change for many constructed players is Galactic Projection Orb. Before the fix, the card could use a spell’s modified cost when deciding what to recast, producing behaviour that did not match the intended original cost check.
After the hotfix, Galactic Projection Orb should evaluate the original spell cost for that decision. Hearthstone September 28 Hotfix therefore changes the practical result of lines that depend on cost manipulation, and players who had stopped using the card because of inconsistent recasts should test it again on the live server.
Riff Finale bug is fixed
Riff cards were also failing to replay the previously played Riff when their Finale effect triggered. Hearthstone September 28 Hotfix specifically names that interaction and gives Verse Riff as an example, so decks relying on the normal sequence should no longer lose the replay simply because Finale activated.
If you still see a Riff fail after the hotfix has fully rolled out, capture the exact cards and order used. Hearthstone September 28 Hotfix fixes the known replay problem, which makes a reproducible post patch failure more useful to report than a general statement that Riffs still feel wrong.
Conditional Battlecries and Book of Faelin
The Battlecry fix covers minions with conditional effects that became unplayable when no valid target existed. Hearthstone September 28 Hotfix restores the ability to play those cards where the conditional effect should simply fail or resolve without a target rather than blocking the minion itself.
Book of Faelin receives a more specific repair. Hearthstone September 28 Hotfix fixes a situation where playing a Dredge card after resetting certain puzzles could cause the game to end in a tie. Players working through that solo content should be able to continue without using a workaround for the affected puzzle state.
What is coming in Patch 36.6.3
Blizzard says Patch 36.6.3 is coming next and will contain more extensive Battlegrounds balance updates. Hearthstone September 28 Hotfix should therefore be viewed as a bug repair step, not the balance patch players may be waiting for after the recent Aberrations and Deity changes.
That distinction matters when deciding whether a live problem is supposed to be fixed today. Hearthstone September 28 Hotfix targets the four listed bugs. Hero, minion and broader Battlegrounds tuning belongs to the upcoming patch unless Blizzard adds another server side change first.
Hearthstone September 28 Hotfix is small but useful, particularly for Riff and Galactic Projection Orb players who were hitting broken interactions. The patch is server side, so test the affected card again on live and keep an eye on 36.6.3 for the larger Battlegrounds balance changes. For the first party details, see official source.
