To Get Custom Sounds ("Chain", "Trap"):
- Install SharedMedia_Causese (https://www.curseforge.com/wow/addons/sharedmedia_causese)
- Restart WoW
- The volume is controlled by master volume so you might have to set it pretty high or max and then adjust other audio channels (sound,music,ambience,dialog)
- If you (or as you should) have the slraid2 big pack locate "06 Shadowsteel Chains" and "06 Flameclasp Trap", and from both disable Actions -> Play Sound (or if you prefer them then disable sound from these auras)
P1 and P2:
- Safezone = Corner
- Traps -> Edge
- Chains -> Mid
P3:
- Safezone = Balls
- Traps -> "P3" remember that the 3rd ones go to mid !
- Chains -> Edge
