After reading a comment on
[Stormchops] procing spell crit effects when it itself crits, I wondered how many other little tricks one can use - ones that might never occur to anyone. So here's a thread for them, and to start them off is one of my own:
A wall of smoke flares works as an excellent way to hide your numbers in AV, or simply spammed all over a defending tower can video lag up the offense.
EDIT: I'll add posted tricks to a list below, for ease of reading. Extremely minor or impractical ones (i.e., farming the cracked power cores) are not listed here. The details will be left to individual posts though. Toss me a PM if any of these don't work.
-General-
Spells whose mana cost is reduced to zero do not put you in the FSR, can stack Pendant of the Violet Eye, and can be used with no mana at all in P2 ROS. (post was specifically on uses of Totem of the Maelstrom)
Magic Dust works on mobs of any level.
[Kreeg's Stout Beatdown] stacks with all buffs except Mistletoe.
Combat Pet trinkets like the Commander's Badge or Gnomish Battle Chicken can be used and swapped before a fight.
[Bloodthistle] stacks with everything.
AoEs and Wanding go through Spell Reflection.
-Raiding-
Leaving someone outside Zul'jin's door will cause tornadoes to follow them.
Kalecgos, and some other bosses, can be despawned by having a hunter shoot and immediately feign death.
Dying from debuffs whose damage counts as yours (Burn, Conflag, etc), or while being untargetable for some reason (Felmyst's MC) will not deal durability damage.
Flame Cap can be used to boost melee dps when Healthstones will not be needed.
A warlock can die outside Aran's door, and a druid can stealth past Chess trash and rez him to the repair vendor.
On absolutely-must-have-that-last-1DPS fights, the blue Use: necks from Jewelcrafting are a substantial dps boost.
Most pets will benefit from Bloodlust if it is used while they are active.
[Thornling Seed] can be used to momentarily distract adds.
[Greater Ward of Shielding] can be used to reduce incoming AOEs on shield classes, or for ROS P1. Cannot be applied in combat.
[Wail of the Banshee] affects bosses.
[Lei of Lilies]'s Lily Root is superior to both Night Dragon's Breath and Luminous Bluetail as a mana consumable.
[Vial of the Sunwell] benefits from % boosts to all healing.
-Professions-
Alchemist's Stone and Gnomish Death Ray can still be used after dropping Engineering.
Gnomish Rocket Boots can guarantee a first cap in EOTS.
Gnomish Battle Chicken's Battle Squawk is a 4-minute 5% haste buff
-Class Specific-
Warlock
Warlocks can summon themselves, then hearth/port and accept the summon to return to where they were.
Infernals and Enslave Demon do not remove Demonic Sacrifice, and can therefore be used for extra damage outdoors.
You can override a DoT curse with a non-damaging one if needed.
Curse of Recklessness does not actually remove fear effects and can be used to ping-pong
Reflected/used on MC'd melee Curse of Recklessness can provide fear immunity or a dps boost.
Reflected Siphon Life or Drain Life is a health gain due to Fel Armor.
Placing a Siphon Life on every target of a multi-mob pull can provide a rather substantial health stream.
Paladin
Shattered Sun Pendant of Might's scryer proc will stack Vengeance.
Holy/Retribution Paladins can use Blessing of Sacrifice on tanks to regain a small amount of mana from the taken damage.
Crit heals with Divine Illumination active will actually increase your mana pool - Illumination restores based on *base* mana cost.
Divine Shield protects from Dark/Demonic rune's health cost.
Hunter
Wyvern Sting's DoT is overwritten by other stings.
Shaman
Earth Shield's healing is calculated when it is cast, so Use trinkets can be used pre-pull to buff it. This also works with ROS P2's aura.
Warrior
[Solarian's Sapphire]'s bonus remains if it is removed after casting Battle Shout, except on the casting Warrior.
Priest
Arakkoa in Terokkar can be mind-controlled for a 5-minute buff that reduces all ability costs by 5%.
Shadow Fiend mana return is based on their damage, which is based on their Attack Power, which is based on your spell damage at time of summoning. Increasing any of these (via BoM, for example) will increase mana return.
Druid
The 3pc Cenarion set bonus to Thorns remains even after the set is removed, except on yourself.
