This should be safe, and allow for custom spells that use titan grip effect to not be affected by damage reduction aura if its not set as spell effect in DBC.
This should be handled by spell effects and not be hardcoded at all, but im not yet experienced enough with the codebase

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:

  1. Copy 46917 (Titan's Grip) as new spell
  2. Remove EffectMiscValue_1 (49152) from DBC / override
  3. Do the Same for 50483 (Titan's Grip Shield - secondary comp)
  4. Aura 49152 is still applied because it's hardcoded to apply not on a particular aura, but on spell effect 155

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

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.
