The build does not have the highest maximum value with a realistic benchmark of 34,758 damage per second (DPS). However, it is easy to learn and deals good breakbar damage.
The best thing about the Easy DPS Deadeye is that you can save on the equipment cost without sacrificing much performance.
In the first step you organize an (at least) exotic medium armor with berserk stats (power, precision, ferocity). This can be bought for about 5 gold at the trading post or obtained from Keeper Jonez Deadrun in the Cursed Shore for 252,000 karma.
Keeper Jonez Deadrun can be found here, near the Murdered Dreams Waypoint [&BCIDAAA=]. If the waypoint is contested, the corresponding meta-event "Temple of Grenth" must be completed first. On Fridays, Saturdays and Sundays this event is regularly completed by players, otherwise some luck is required. Just check back every 30 to 60 minutes to see how things are going.
IMPORTANT: the Rubicon armor is soulbound upon receipt. So you have to go with your engineer to buy the armor.
After that you should buy armor runes. Superior Rune of Infiltration are ideal. Nika's armor already has the right runes in it. For the Rubicon armor, you can buy the runes cheaply at the trading post. You need 6 runes of one kind (mixing runes generally gives worse bonus effects. You then place one rune in each of your new armor pieces.
You need two daggers with berserk stats. You can buy them for about 1 gold each in the trading post.
After that you need weapon sigils. Unfortunately you can't save anything here and have to buy two sigils for about 3-4 gold each.
Place the sigils in the upgrade slots of your new daggers.
Jewelry has the greatest potential for savings. Buying the jewelry regularly costs about 23 gold. If you collect a few materials from Living World Seasons 3, 4 and Icebreak Saga together, you can not only save all the gold, but even get ascended (and thus better) jewelry.
For a complete equipment you need: 2x accessory, 2x ring, 1x amulet and 1x back piece. In contrast to the runes you can mix freely here (e.g. 2 ascended and 4 exotic pieces).
IMPORTANT: Ascended trinkets are "Unique". This means you can only equip one piece of jewelry with the same name at a time. So make sure you buy two different ascended rings and two different ascended accessories.
There are many different ways to get your ascended parts. For example, if you don't have enough laurels or ectoplasm orbs for Althea's Ashes, you can get another Accessory for 375x Eternal Ice Shard + 56,000x Karma. It's best to find out which trinkets are best for you to obtain.
Using Deadeye's Mark (F1) poisons your opponent.
You get +160 power as you use daggers.
When you poison enemies, you inflict additional weakness on them.
You get +80 power and +120 additional power while you are revealed. You are always revealed for 3 seconds after you hit an enemy while you had stealth. The Reveal mechanic is an important part of this build.
For each different condition on your opponent, you deal 2% more damage. Raid bosses usually have up to 10 different conditions on them. So you can deal up to 20% more damage.
If your opponent has less than 50% of his life, you deal 20% more damage.
As long as your life is above 90%, you have a 10% higher chance of critical hits.
You deal 7% more critical damage when you have more than 90% health.
You also have a 7% higher chance of critical hits as long as you flank your opponents (stand behind them or to the side). You always want to stand behind your opponent to take advantage of this.
Every 10 seconds, you gain 4 seconds of fury when you hit an enemy that has less than 90% health.
You get ferocity equal to 10% of your precision. With fully exotic equipment, this equals +198 ferocity.
You deal 10% more critical damage against enemies with more than 50% health.
You get 2 seconds of extra fury when you critically hit an enemy while you have fury. So you almost always have fury, which is a very important boon in this build.
Additionally, you get +250 ferocity as long as you have fury. This is a very good boost, especially since you almost always have fury.
Your F1 skill becomes Deadeye's Mark (F1).
You can get malice now. You can get up to 5 malice. For each malice, Malicious Backstab (Dagger 1) deals 10% more damage while consuming the malice. When you have 5 malice, you gain stealth when you use your F2 skill.
Using your F1 skill or Malicious Backstab (Dagger 1) gives you an additional 1 malice.
When your opponent dies, your F1 skill is immediately recharged and you gain 3 seconds of regeneration.
You deal 1% more damage for each different boon on you. In a normal raid fight, you have up to 7 different boons, which equals 7% more damage.
You also get +180 concentration.
You deal 10% more damage to enemies you have marked and receive 10% less damage from them.
You get 4 seconds of quickness when you mark an enemy.
As long as you have quickness, you get +200 power and +200 precision.
Your Dagger auto-attack is a chain of Double Strike > Wild Strike > Lotus Strike. The entire auto-attack chain takes only 1.68 seconds, so it's very fast. Wild Strike does more damage than Double Strike. Lotus Strike does more damage than Wild Strike plus two stacks of poison.
So it makes sense to always cast the complete chain if possible.
As long as you are stealthed, you have Malicious Backstab (Dagger 1) instead of Double Strike (Dagger 1). This skill deals very high damage when you stand behind your opponent. And high damage when you stand in front of your opponent. You should always try to stand behind your opponent, as you will deal much more damage that way. Also gets up to 50% more damage from malice.
A good attack that does more damage the lower your target's health is. You should only use this skill when your opponent has less than 25% health.
An attack during which you evade for 0.5 seconds and trip enemies three times with low damage. Each hit inflicts bleeding. Because of the low damage, it is not part of the rotation. Because of its short duration, it is also not good defensively for evading.
A weak attack that cripples opponents. Due to the low damage, it is not part of the rotation.
An average attack that gives you stealth and gives enemies 5 stacks of vulnerability. You use this skill to gain access to Malicious Backstab (Dagger 1) through stealth.
A healing skill that passively heals you every time you attack an enemy. You never want to activate the skill so you always get the passive healing.
You passively gain +180 power. When you activate the sigil, you get +540 power for 5 seconds instead and the sigil recharges for 20 seconds.
You want to activate the Signet mainly in phases where you want to deal large amounts of damage quickly and pack as many Strong Attacks as possible into the 5 seconds, especially twice Malicious Backstab (Dagger 1).
You will passively receive one additional initiative every 10 seconds. This helps to quickly use enough Cloak and Dagger (Dagger 5) to have Malicious Backstab (Dagger 1) available. You never want to activate the skill so you always get the passive initiative.
A skill that deals good damage to your marked target.
A skill that deals a high amount of Breakbar damage, in which your next attack and your allies' next attacks deal 150 Breakbar damage each. With a maximum of 5 players hit, that's 750 breakbar damage. This makes it the strongest CC skill in the game.
You mark your target and get a stack of malice by Malicious Intent.
The stolen skill has different effects depending on your opponent's class. However, the important thing is that using the skill gives you stealth and thus access to Malicious Backstab (Dagger 1).
The most important thing about any Guild Wars 2 build is the rotation. You can have the perfect gear and pick up the right abilities, if you don't master the rotation, a player with worse gear and better rotation will always do more damage/DPS than you.
Most build guides for Guild Wars 2 on the internet are created by speedrun guilds and are designed for players who want to achieve maximum damage through lots of practice. However, the raids can also be defeated with significantly less damage. Also, not every player has time or willingness to practice the rotation for several hours a week. To play a rotation to perfection, hours of practice are unfortunately necessary. However, if you understand the rotation well, just a few hours of practice are enough to play the class well enough for relaxed raids and beginner raids.
You always want to have the boss enemy marked with Deadeye's Mark (F1). You will inflict much more damage and suffer less damage from the boss.
Stand behind your opponent
You do much more damage when you stand behind your opponent. Therefore, you should always try to stand behind your opponent.
Main damage combination
Your main damage combo is based on performing Malicious Backstab (Dagger 1) twice, Shadow Flare (Utility 9) once, and two full Autoattack chains during the active effect of Assassin's Signet (Utility 7). (See Burst Rotation under "Ideal Rotation").
If you can't perform your main damage combination right now, or are saving it for an important burst phase, just perform full autoattack chains.
The ideal rotation consists of a Burst Rotation that deals the most damage and the Autoattack Chain that you use until your burst rotation is available again.
Burst rotation when opponent is below 25% health
