Sylas: The Unshackled
Sylas is a versatile and dynamic champion known for his ability to steal and use enemy ultimates. He excels in the mid-lane but can also be flexed into other roles. His gameplay revolves around using the enemy's strengths against them and adapting his strategy based on the ultimates he steals.

Role: Burst Mage/Fighter

Abilities:

Petricite Burst (Passive): After casting a spell, Sylas's next basic attack whirls his chains around him, dealing damage.
Chain Lash (Q): Sylas lashes out with his chains, damaging and slowing enemies.
Kingslayer (W): Sylas lunges at a target with a powerful strike, healing himself if the target is below half health.
Abscond/Abduct (E): A two-part dash. The first dash grants a shield, and the second pulls him to an enemy, stunning them.
Hijack (R): Sylas steals an enemy champion's ultimate ability and can cast it as his own.
Irelia: The Blade Dancer
Role: Fighter/Assassin

Abilities:

Ionian Fervor (Passive): Hitting enemies with abilities grants attack speed, stacking up to five times.
Bladesurge (Q): Dashes to an enemy, dealing damage and healing Irelia. If the target dies, the cooldown resets.
Defiant Dance (W): Charges up a defensive stance, reducing incoming damage and then unleashing a powerful strike.
Flawless Duet (E): Sends out two blades that converge, stunning and damaging enemies.
Vanguard's Edge (R): Launches a barrage of blades that explode outward, forming a wall that damages and disarms enemies.
Skill Order: Max Q first for mobility and damage, then E for crowd control, and W last for damage mitigation.

Runes:

Primary (Precision): Conqueror (sustained damage), Triumph (restore health on kills), Legend: Tenacity (reduced crowd control), Last Stand (increased damage when low).
Secondary (Resolve): Bone Plating (reduced damage from burst), Unflinching (tenacity and slow resist).
Gameplay Tips:

Early Game: Focus on farming and stacking your passive. Use Q to last hit minions and harass the enemy when safe. Engage with E for stuns.
Mid Game: Look for opportunities to roam and secure kills. Your mobility allows you to move quickly between lanes.
Late Game: In team fights, look for flanks and dive onto the enemy backline. Use R to disrupt and disarm multiple targets.
Kassadin: The Void Walker
Role: Assassin/Burst Mage

Abilities:

Void Stone (Passive): Reduces magic damage taken and allows Kassadin to move through units.
Null Sphere (Q): Fires an orb of void energy, dealing damage and silencing the target.
Nether Blade (W): Empowers his next attack to deal bonus damage and restore mana.
Force Pulse (E): Emits a cone of void energy, damaging and slowing enemies. Requires charges from abilities cast nearby.
Riftwalk (R): Teleports to a location, dealing damage on arrival. Repeated use increases mana cost and damage.
Skill Order: Max Q for poke and survivability, then E for damage and slow, and W last for empowered attacks.

Runes:

Primary (Domination): Electrocute (burst damage), Taste of Blood (sustain), Eyeball Collection (bonus AP), Ravenous Hunter (spell vamp).
Secondary (Sorcery): Manaflow Band (increased mana regen), Transcendence (cooldown reduction).
Gameplay Tips:

Early Game: Play safe and farm with Q. Avoid unnecessary trades until you have your ultimate.
Mid Game: Once you have R, look for isolated targets to burst down. Use your mobility to avoid counter-attacks.
Late Game: In team fights, use R to dart in and out, focusing on the enemy backline. Your high burst damage allows you to quickly eliminate squishy targets.

Recommended Team Compositions
Strong Engage Composition:

Irelia: Works well in teams with multiple crowd control abilities to set up her engages. Pairs well with champions like Leona or Sejuani who can provide reliable CC.
Kassadin: Benefits from teams that can protect him early game and allow him to scale. Champions like Janna or Lulu can provide the necessary protection.
Scaling Composition:

Irelia: Scales well with items and can become a significant threat in the late game. Needs a team that can support her through the early game.
Kassadin: One of the best scaling champions in the game. Needs a team that can stall the game until he reaches his power spikes.
Individual Skill Composition:

Irelia: Can solo carry games if ahead. Requires a high skill level to manage her resets and engage effectively.
Kassadin: Can also solo carry games with his mobility and burst. Requires good map awareness and positioning to maximize his potential.
Conclusion: Why Kassadin is Recommended
Strengths and Weaknesses:

Irelia:
Strengths: High mobility, strong dueling potential, effective against squishy targets.
Weaknesses: Squishy, reliant on hitting skill shots, can be countered by heavy CC.
Kassadin:
Strengths: Exceptional mobility, high burst damage, excellent scaling.
Weaknesses: Weak early game, reliant on reaching level 16, mana-intensive.
Recommendation: Kassadin is recommended for long-term play due to his exceptional scaling and late-game dominance. While Irelia offers high-skill expression and can be incredibly impactful, Kassadin's ability to turn games around in the late stages makes him a more consistent and reliable choice for most players.

Laning Against Sylas: Strategies for Irelia and Kassadin
Sylas is a highly versatile and unpredictable champion due to his ability to steal ultimates. When leaning against Sylas, it's crucial to understand how to manage his strengths and exploit his weaknesses. Here's a detailed guide on how to handle Sylas with Irelia and Kassadin, focusing on early, mid, and late-game strategies, as well as team fight techniques and practical gameplay tips.

Irelia vs. Sylas
Early Game
Laning Phase: Irelia should focus on hitting her Ionian Fervor (Passive) stacks by last-hitting minions with Bladesurge (Q). Use Defiant Dance (W) to mitigate Sylas’s poke and Flawless Duet (E) to set up stuns and disengage from his all-ins.
Positioning: Stay behind minions to avoid Sylas's Chain Lash (Q). Trade only when you have your passive stacked for increased attack speed and damage.
Mid Game
Objective Control: Irelia’s mobility allows her to contest objectives efficiently. Use Vanguard's Edge (R) to initiate fights and disrupt Sylas. Always be mindful of Sylas stealing your ultimate; try to bait it out or engage when it's on cooldown.
Split Pushing: If ahead, Irelia can split push effectively, forcing Sylas to respond. Utilize Q for quick wave clear and E for protection against engages.
Late Game
Team Fights: Irelia should look for flanking opportunities. Engage with R to disarm and deal AoE damage, then use Q resets to dash between targets. Focus on eliminating key threats quickly, especially if Sylas is trying to dive into your backline.
Kassadin vs. Sylas
Early Game
Laning Phase: Kassadin should play defensively, focusing on farming with Null Sphere (Q) to avoid taking too much damage from Sylas. Use Nether Blade (W) for mana sustain and to last-hit minions safely.
Positioning: Maintain distance and avoid extended trades. Use Q to poke and silence Sylas, preventing him from chaining his abilities effectively.
Mid Game
Objective Control: Once Kassadin reaches level 6 and unlocks Riftwalk (R), he becomes significantly more mobile. Use this to secure kills on overextended enemies and assist in objective control. Be cautious of Sylas stealing Riftwalk; it can be used against you to escape or chase.
Roaming: Kassadin's mobility allows for effective roaming. Look for opportunities to help other lanes and secure kills.
Late Game
Team Fights: Kassadin excels at diving the backline. Use R to position yourself strategically, burst down squishy targets with Q and E, and reposition quickly with R. Avoid confrontations with Sylas until you’ve whittled him down or until his key abilities are on cooldown.

Team Fight Strategies
Irelia:

Engage: Use Vanguard’s Edge (R) to initiate, followed by Flawless Duet (E) to stun multiple enemies. Utilize Bladesurge (Q) resets to dart around the battlefield, focusing on high-priority targets.
Peel: If Sylas dives your backline, switch to a peel role, using E and W to protect your carries.
Kassadin:

Engage: Kassadin should flank and use Riftwalk (R) to dive onto the enemy backline. Combine Null Sphere (Q) and Force Pulse (E) to burst down key targets, then reposition with R.
Peel: In situations where Sylas is diving your backline, use Q to silence him and E to slow. Use R to reposition and continue providing burst damage.

Practical Gameplay Tips for Kassadin
Farm Safely: Use Null Sphere (Q) to farm from a distance and avoid unnecessary trades in the early game.
Itemization: Build items like Rod of Ages and Archangel’s Staff for scaling and survivability. Zhonya’s Hourglass is crucial for avoiding burst damage.
Cooldown Management: Keep track of your Riftwalk (R) stacks to manage mana efficiently and maximize burst potential.
Engage Timing: Time your engagement around Sylas’s cooldowns, especially if he has stolen a powerful ultimate. Use R to dodge key abilities. However, when some players explore further and become familiar with a certain hero, some players will choose to buy League of Legends items.
