NeedToKnow lets you monitor specific buffs, debuffs, cooldowns, and totems as timer bars that always appear in a consistent place on your screen.
Note that 4.0 is a pretty big update. I recommend backing up your WTF folder before upgrading just in case there's a problem!
NeedToKnow is especially useful for monitoring frequently used buffs, debuffs, and cooldowns. For example, a rogue could configure NeedToKnow to show timer bars for Slice and Dice, Rupture, and their own stack of Deadly Poison VII. A death knight could use it to track their own diseases on a mob.
The bars only time things when the addon is locked. Type "/needtoknow" or "/ntk" to lock/unlock the addon. You can also use the buttons in the AddOns tab of the Blizzard Interface Options menu.Why won't NeedToKnow track this buff/debuff? It works for other things.
Check your spelling and capitalization. Also remember that buffs and debuffs sometimes have different names than the items and abilities that apply them. The Death Knight ability Icy Touch, for example, applies a DoT called Frost Fever. If you're using a SpellID, make sure you have the correct one.How do I track multiple buffs or debuffs on a single bar?
Enter the name of each buff/debuff separated by commas. They are prioritized according to order. For example, "Rake, Lacerate" will display Rake until it expires and then it will track Lacerate. "Curse of Recklessness, Curse of Exhaustion, Curse of Shadows" is a good way to track single-instance curses.How do I get more bars?
You can enable more groups of bars by going into the Interface settings off the main menu and choosing the AddOns tab. If four groups of six bars isn't enough for you, consider another timer bar addon. Also consider rethinking your UI.How do I get NeedToKnow to track my own DoTs but not those applied by other members of my class?
Select "Only show if cast by self" in the bar's configuration menu.
