Buffs, procs, and auras. So going over the Twitter madness over Revenge on the front page, I started mulling over buffs, auras, and other kinds of positive, indirect skills player characters have used over the years in Diablo and other games. There are several types we've seen thus far, and I wanted to know which ones were the most interesting to people here. Let's look at the types. Type A: Long duration, short/no cooldown, persistent buff. Possible secondary effects. -These are your Chilling Armor spells, and Barbarian Warcries. You'll always have them active in any situation. D2's UI never let you know when they were about to fall off, which was annoying. -Monk/Paladin/Druid auras fall into this category, although they are generally mutually exclusive; the strategy comes into which aura to use in which situations. Given the 7 skill limit, most monks probably won't have more than one or two. -Assassins also had persistent, always want them buffs, but were also mutually exclusive (couldn't use Burst of Speed and Fade at the same time). Type B: Long duration, short/no cooldown, absorption buff. Possible secondary effects. -Bone Armor and Cyclone Armor. Buffs that you'd want to keep up all of the time, but couldn't due to monster interaction. -This can also include proc armors that have limited charges; Lightning Shield in WoW can be "used up" when something hits the Shaman enough times. -In WoW, absorption mechanics (Death Knight Blood shields, Priest shields) are on timers and have cooldowns. From what I've seen in the PvP videos, Wizard Diamond Skin also is on a timer and has a cooldown. More on this below. Type C: Short duration, noticeable cooldown. Generally, the duration is shorter than the cooldown; the buff is designed to fall off. -"Oh crap" buttons defensively, or "I have to go to the bathroom so let's kill everything in this room NOW" buttons offensively. -Examples: Ignore Pain (defensive), Bloodlust from WoW (offensive), Sprint (either; running away or catching a runner). -These can generally be much more powerful than Type A or Type B, b/c they are designed to never be up 100% of the time. Damage absorption may have crossed that threshold, especially in PvP. Type D: Active skills which can only be used after procs or other conditions. May or may not have a cooldown. -The Revenge skill which started this whole discussion. -Very tactical, but needs special care and polish to make it work; good UI elements to let the player know it triggers are critical. Also, a timer to give the player a chance to push the appropriate button is almost mandatory. So which kinds of proc skills/buffs do you guys prefer? Which are most fun?
