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, Rhydian walks, talks, summons portal and walks back. Portal is working and teleports me directly to where I can complete the quest. Portal disappears after some time if I don't use it. All looking good.

In the "how to test" we need to .quest add 13080 before completing it.

One minor issue is that Rhydian starts talking 0.5-1s before stopping, which looks a bit odd... It's also different here, where she starts talking at the same time that she stops: https://www.youtube.com/watch?v=1njQsRaxCc4

Change the MOVE_TO_POS to set a PointID, then separate the actionlists into two. Then create a new event MOVEMENTINFORM, type 8 (Point) and PointID the same as the one set in the first step. This event fires the second part of the actionlist. This makes sure the line is spoken after reaching the point, not before.
