Changes Proposed:

This PR proposes changes to:

  • Core (units, players, creatures, game systems).
  • Scripts (bosses, spell scripts, creature scripts).
  • Database (SAI, creatures, etc).

Issues Addressed:

SOURCE:

The changes have been validated through:

  • Live research (checked on live servers, e.g Classic WotLK, Retail, etc.)
  • Sniffs (remember to share them with the open source community!)
  • Video evidence, knowledge databases or other public sources (e.g forums, Wowhead, etc.)
  • The changes promoted by this pull request come partially or entirely from another project (cherry-pick). Cherry-picks must be committed using the proper --author tag in order to be accepted, thus crediting the original authors, unless otherwise unable to be found

Tests Performed:

This PR has been:

  • Tested in-game by the author.
  • Tested in-game by other community members/someone else other than the author/has been live on production servers.
  • This pull request requires further testing and may have edge cases to be tested.

How to Test the Changes:

This PR implements a change to the core loot system to fix an issue related to quest-based loot eligibility. The change ensures that only players who accept and own the associated quest can roll and receive specific loot items, such as "Shadowfrost Shard" or "Acidic Blood", while players without the associated quest are unable to participate in looting these items. The change ensures that the loot system works more accurately across groups with different quest states.

  • [x ] This pull request can be tested by following the reproduction steps provided in the linked issue
  • This pull request requires further testing. Provide steps to test your changes. If it requires any specific setup e.g multiple players please specify it as well.
  1. Go to ICC and defeat the Bosses Rotface's and Festergut's - 25N and 25HC
  2. Check if the Loot is appearing normally for those who have the quest 24545

How to Test AzerothCore PRs

When a PR is ready to be tested, it will be marked as [WAITING TO BE TESTED].

You can help by testing PRs and writing your feedback here on the PR's page on GitHub. Follow the instructions here:

http://www.azerothcore.org/wiki/How-to-test-a-PR

REMEMBER: when testing a PR that changes something generic (i.e. a part of code that handles more than one specific thing), the tester should not only check that the PR does its job (e.g. fixing spell XXX) but especially check that the PR does not cause any regression (i.e. introducing new bugs).

For example: if a PR fixes spell X by changing a part of code that handles spells X, Y, and Z, we should not only test X, but we should test Y and Z as well.

Tested in 25NH with 3 characters. Two character had the quest. One didn't.
The character that didn't accept the quest wasn't able to roll for either the Saronite or Acidic Blood (I tested both of them)
The characters with the quest could roll and the usual system worked fine.
