Getting Set Up

use:

/lb } for menu

/lb s } to show

/lb h } to hide

/lb l } to lock the window in place and hide buttons

/lb p } to auto-generate party frames

Once you have it shown, click on what you want your frame's target to be. Then click the middle button next to the frame, this will set the frame's target to whatever your current target is. If your current target is not in your raid you will need to use /focus on that target before clicking the target selection button (this is because there is no other unit id for such a unit). You may add unit frames using the + button to the left of each frame and you may remove unit frames using the - button.

Editing options for Lifebloomer are located in WoW's Interface Options menu (made movable by Lifebloomer!).

Usage

You will notice that the lifebloom bar will turn from blue, to purple, to red. ideally, you will reapply lifebloom when the bar turns purple, this purple region indicates when lifebloom has 1 second plus your lag left. if you cast it when the bar is purple, your previous lifebloom will get it's 5th tick in before the next one is applied. when the bar turns red (1 second left) you know that lifebloom will run out very soon if not promptly reapplied. Do not wait until the last millisecond to cast lifebloom because your lag will cause you to lose your stacks. Also, there is a red overlay which indicates the global cooldown, you should be able to cast again as soon as this bar completely disappears.

Note

It is possible to stack lifebloom on up to 4 targets (more with the talent and glyph changes in WotLK), this requires a very active player and no "line of sight" issues. However doing so will drain your mana fairly fast so you don't want to do this if you do not have to. By paying attention to each tank's DTPS you should be able to judge how many hots you need on them, if any at all.
