Cassia is a Ranged Assassin Hero from the Diablo universe. She is the same Amazon the player can control in Diablo II.
After shattering the Worldstone, the young Amazon Cassia had changed. She had seen hatred, terror, and destruction firsthand. If the Askari were to survive the coming darkness, they needed an army. She would begin their training immediately.
Background[]
A powerful warrior, Cassia belonged to nomadic bands who roamed the plains near the South Sea. The wandering of these groups often brought them into conflict with other peoples, so Cassia was accustomed to fighting to defend her own. She was much sought after as a mercenary—Cassia was loyal to those who hired her, as long as her own ends were also served.
Gameplay Summary[]
Cassia is an Assassin that can be played as either a focusing on poke or high sustained damage. She is unique as her trait, Avoidance, makes her extremely resilient against basic attacks as long she is moving. In addition, she passively deals increased damage to enemies under blind effects. These combined makes Cassia a natural counter for any Hero that relies on physical damage.
Overall, Cassia can fit into many team compositions due the flexibility of her gameplay style, however, she gains added value if her allies can also blind enemies, further increasing her bonus damage uptime.
Strengths[]
- Avoidance naturally makes her a strong counter to Heroes that rely on basic attack to deal damage.
- For instance, Tracer's rapid, weak attack barely tickles her, and Cassia is better able to wander around a sieged Sgt. Hammer than most.
- Passively deals bonus damage to blinded opponents.
- Flexible talent tree, allowing her to focus on either poke through abilities, or sustained damage through basic attacks.
- Has access to an area of effect burst oriented talent at level 1, Charged Strikes.
- Can gain a powerful tool of self-sustain through the level 4 talent Ring of the Leech.
- Lightning Fury provides Cassia with a very effective poke, specially if talented into.
- Blinding Light covers a decent area of effect.
- Fend is a powerful finishing move, specially if opponents are affected by some kind of crowd control.
- It also provides decent waveclear if minions are blinded.
- Ball Lightning can deal massive damage under the right circumstances.
- Valkyrie is a powerful displacement tool if Cassia has proper setups and/or follow ups to do so.
Weaknesses[]
- Has lower Basic Attack range compared to other ranged Heroes, making engaging somewhat more difficult.
- Since Avoidance only works against basic attacks, enemies who focus on spell damage (like Jaina, Li-Ming, and Kael'thas) can send Cassia scurrying in a hurry.
- Has no mobility outside of Fend, which once cast, commits Cassia to that position, which can often leave her vulnerable if poorly timed.
- She finds difficult to compete against other ranged Assassins that can often outperform her in terms of damage and utility.
- Both Heroic Abilities are relatively easy to avoid if the enemy team is not under crowd control.

Talent Builds[]
- Lightning Fury Build: focused maximizing Lightning Fury's poke damage and spam capacity. The core of this build lies in the level 1 talent, Thunderstroke, which allows Cassia to use the ability more often by granting it another charge and reducing its mana cost; and Pierce at level 16, which allows Cassia to maximize the damage potential and hit multiple Heroes at once. This build is recommended when facing multiple ranged assassins focused on ability damage ("mages").
- Fend Build: focused on maximizing Fend's raw damage to make it devastating with the right setup, while allowing Cassia to blind her opponents more often thanks to Seraph's Hymn, meaning more damage uptime. This build is recommended when the allied team features heavy crowd control abilities (such as stuns and roots) and when the enemy team has no reliable interrupts to prevent Cassia from channeling Fend.
- Charged Strikes Build: focused on improving Cassia's Basic Attack damage through the key talent Charged Strikes, which allows her to put constant pressure on enemy groups. The synergy of the build lies in three other talents that allows Cassia to maximize her damage output: Grounding Bolt at level 13, which pairs perfectly with Martial Law at level 16, and lastly Titan's Revenge. This not only makes Cassia a very strong Basic Attacker, but also makes her a threat to Warriors and other high health Heroes. This build is recommended against a strong frontline featuring multiple Melee Heroes.
Tips[]
- Mastering "stutter-stepping" is key when playing Cassia, to both maximize her damage output while keep her under the effects of Avoidance.
- Ring of the Leech is an essential talent for Cassia's survival, as it adds a very much needed self-sustain tool, easily outclassing the other talents in this tier.
- Use Lightning Fury to poke enemies from a safe range, while hitting with basic attacks.
- Try to hit as many opponents possible with Blinding Light to maximize the damage output (and also healing if Ring of the Leech is taken).
- Try to use Fend as a finishing move to execute targets; save it when they're under crowd control effects such as stuns and roots to ensure all the hits will land.
- Use Ball Lightning when opponents are clustered, or to win 1v1 situations.
- Use Valkyrie is to interrupt opponents' channeled cooldowns, or to pull low mobility Heroes who are out of position.
Matchups[]
Pairings[]
While Cassia pairs well with most Heroes due the flexibility of her talent tree and gameplay style, she shines when paired with Heroes that can provide additional sources of blind, as well strong crowd control to allow her to hit the opponents more effectively.





Effective against[]
Cassia's entire kit is built around combating Basic Attackers, as she can heavily mitigate damage thanks to her trait, and blind opponents.



Effective foes[]
Cassia is greatly hindered against teams that feature heavy spell damage, since she has no forms of escape or ways to reduce that kind of damage. Raned burst oriented "mages" can easily worn her out, specially since her basic attack range is lower than other ranged Heroes.
