Healing Addons

Bandaid

Bandaid helps healers maximize the effectiveness of their AoE heals by calculating the number of players that will be affected and estimating the efficacy of the heal. These numbers are exposed as global variables and are intended to be displayed using addons that support custom Lua scripts such as WeakAuras or TellMeWhen.

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.

Can't Heal You

Can't Heal You will automatically whisper people who you try to heal or buff, but who move out of your range or aren't in line of sight. That way, they know you're trying, and can possibly move to help you heal them.

Clique

Clique is a simple GUI that lets you assign click-casting for any number of unit frames. Click casting allows you to define the behavior the game takes when you click on a frame. This can be casting spells, running a macro, using an item, or something as simple as changing targets or assisting a unit.

Grid

Grid is a modular, lightweight and screen-estate saving grid of party/raid unit frames. Optional modules can be assigned to up to 7 possible indicators: each corner, a border center text and center icon - to highlight specific units (and if you prefer to only show units in range, this is posible too). Grid comes with a bunch of modules (aggro indicator, incoming heals, auras (debuff types, shield, renew, rejuv, mortal strike,...), mana, health deficit,...), but it's easy to add your own modules (see the developer API).

Healium

Healium provides a customizable, intuitive, compact, no-clutter interface optimized to make it easy to heal. Healium places your healing spells onto buttons right next to each person's healthbar. The buttons will cast the heal on the person they are beside of, without the need for you to target the person first. Player healthbar's are compact and close to each other which reduces the amount of screen space you have to look over to monitor the party's health. The healing buttons are very close by, minimizing the space you have to move your mouse, and thus the time required, to cast the heal. Unlike other healing focused addons, Healium does not require you to set up complex key combinations (shift, ctrl, and alt) to cast your heals. In Healium, you just click a healing button next to the person's health bar. There is no memorization of key combinations required, or even allowed!

Quick Heal

When enabled, damage taken bars will appear beside each player and party unit frame. These bars increase with the amount of damage a player in the party receives, changing colors from green to yellow to red upon death. When in a raid, damage taken bars will appear beside the name of everyone in the raid for quick and easy monitoring. A range checking option also gives the ability to focus on party and raid members within range.
