Boss Encounters

BigWigs

Boss alert mod. It consists of many individual "boss modules", mini addons that are designed to trigger alert messages and timer bars for one specific raid boss each. Modules are activated when you target or mouseover a Boss, or if any other BigWigs use in your raid does. In most cases only one module will be running at any given time.

Blizzard Raid Frames - Indicators

Configurable indicators for Blizzard Raid Frames showing time of buffs/debuffs on all units in the raid. There are 9 indicators for each raid member, one on each corner, one on each side and one in the middle. Indicators can be configured to show any buffs/debuffs of your choice and you can configure several buffs/debuffs in the same indicator. Some simple options lets you select to show only if the buff is missing, only cast by you, stack sizes and more. As an added bonus there's also an option to turn off the standard buff/debuff icons.

Misc Raid/Instance Addons

Angry Boss Reminders

This addon was written by the guild Angry (US-Illidan) to help raiders switch to the proper talents and gear for each boss during a raid. You can configure the particular talents/gear that you'd like the addon to watch for, on a per-boss basis. As you arrive in each boss's room, you'll be reminded about any talents/gear that need to be changed, and you can simply click on the reminder icon(s) to install/equip automatically.

Atlas

Atlas is an addon for World of Warcraft that includes detailed maps for every instance in the game. Originally, Blizzard neglected to include maps for instances. However, after a number of years Blizzard began to include official maps for some instances. These official maps are in the same hand-drawn style as the built-in world maps. Conversely, the Atlas maps are based on data used by the minimap, which provides a more detailed, accurate, and colorful representation. You can think of this as the difference between a street map and a satellite image.
curse

BossesKilled

Creates a row of buttons showing you how many bosses you've cleared in each LFR wing, and the buttons light up if you're currently queue'ing for the corresponding raid. No more memorizing, or like me, having to go through the dropdown menu and mouseover the small "!" icon to see which bosses are down and which you still need to kill all the time.
curse

GTFO

This addon provides an audible alert when you're standing in something you're not supposed to be standing in. In some cases, you'll be warned before you start taking damage. It's particularly useful for individuals that play with their spell graphics turned down or for those that just need a little extra help being told to GTFO. It also helps out with PvP when you can't tell who's casting the AOE. | JuniorDeBoss Youtube Review

LiteAssist is a very basic addon to replace the standard /assist macro. It provides extra key bindings to learn who to assist and to assist them.

targetAssist

Anyone else miss MainAssist? targetAssist is my attempt to recreate the basic functionality of that wonderful addon. targetAssist provides unit frames that track tanks and main assists in your party or raid, along with their current targets. You can position the frames by dragging the header bar. Targeting buttons can be arranged above or below the header.
