A few simple icons/notifications for the new Titan Rune Dungeon effects in WOTLK Classic.
Utgarde Keep / Pinnacle - Plays an air horn and shows icon if you are standing in Icy Path
Azjol Nerub / Old Kingdom - Shows an icon if someone in your group is web wrapped, also shows a timer for your own web wrap
Culling of Stratholme - Shows a timer for your own infected debuff, also shows an icon if someone in your group has the infected debuff.
DTK / Gundrak - Shows an icon and plays a sound if your current target is standing in Blood of the Loa. Only shows if you are the tank. (checks buffs for Frost Presence, Dire Bear Form, Defensive Stance or Righteous Fury)
