Ah, this looks fun! I main a Rogue, and Jayya is my only character over level 35. I've enjoyed playing her quite a bit, and have accumulated a number of tips and tricks over the years. I'll look at posting more notes later, but here's some to start:
Doing Damage:
--Carry Emeralds and proactively ask Shamans to Avatar you. Avatar is one of the largest damage boosts you can get.
--You can camp Avatar and remain in voice to log in in many situations to preserve the buff for a fight and allow the Shaman to recharge to Avatar another Rogue.
--Duelist is the go-to damage discipline for short fights, Avatar of War or fights like Sontalak/Zlandicar where you're going to eat a lot of AOEs before possibly getting aggro. Basically, if you're in a fight where you are going to die before you can react if you catch aggro, use Duelist. In most other fights, Nimble is going to be a much stronger choice because successfully catching a mob with Nimble on tank death extends the fight by 12 seconds and allows for chain to stabilize on the next tank. If you buy the raid an extra 12 seconds to burst down Vyemm or Tunare you add much more damage than Duelist ever would.
Leveling
--Leveling is easiest by joining traditional groups and stabbing things
--https://wiki.project1999.com/Shardwing_Courier is a good solo target if its up while you're traveling to/from ToV and you're carrying snare poison for bow kiting or geared/raid buffed enough to kill it. You can turn in the quest drop to Fjokar while using Sneak while KoS, and its worth the same XP as soloing ~7 blues.
Hide/Sneak
--Sneak makes you undetectable by any mobs in the back 3/4 arc. Nothing in the game can see through sneak.
--Sneak lets you pickpocket mobs if you are KOS, as well as do quest turnins to KOS mobs. Hide needs to be off.
--Hide makes you invisible to everything from all directions, but some specific mobs can see through it. Some notable examples include: All ToV named mobs, all VP named Dragons, many Flurry drakes in ToV (but not all), Fire Giants in Sol B, a guard on the stairs to Emperor Crush in Crushbone, and some oozes in howling stones.
--Rogues can move with both Hide+Sneak on. Their movement speed is slowed, but the amount decreases with level. A SoWed Rogue can run while Hide+Sneak faster than an unsowed character.
--Because no VP trash sees hide/sneak and rogues can open the Phara Dar door, a VP allows you to easily walk to sky solo.
--Rogues can test if they're on an aggro table by trying to Hide. If they get the evade message, they're on some mobs aggro table. If they just get the normal hide message, they're clean. That lets them stay in when its unclear whether the raid is dirty and everyone is cycle camping because they are (the only class who is?) able to check for sure.
Pulling and Bows
--Rogues can do a lot of pulls. They lack feign death and DA, which hurts, but they can start trainouts from unexpected or difficult to reach places with Hide+Sneak and have a relatively easy to acquire 340 range aggro tool with Exquisite Velium Reinforced Bow + Flight Arrows that allows for aggoing things deep behind see invis KOS stuff. Examples include:
Pulling Armor of Zek (

Pulling Statue on Quake (can loiter at door and pull if you see anyone running up to compete, can start Statue Trainout with bow from past the door to state room)
Training and holding mobs for a tag with Nimble+CotH or TL box (such as this Zlexak Split:

Pulling Tormax's Throne room while KOS (you can shoot across at the giant next to Yetarr while sneaking, which gives enough range to turn hide back on and run out before the giants on your side aggro)
Pulling Dlammaz (just shoot him and turn hide back on and train out)
Pulling Ymmeln from outside normal leash range to a bonewalked Necro pet to bring Ymmeln in to 4 way.
Pulling VP: there's a whole art to this. I'm not very good at it yet, but Rogues are usually backup to Bards there since we can quickly get anywhere in zone regardless of see invis status. The actual trainout is tricky though, since Hide+Sneak is too slow to outpace racnars.
