Guide: Nais the Shadowthief

In short

Nais the Shadowthief is a mythical attack champion from the Sylvan Watchers faction, a true nightmare for enemies in the Arena. He specializes in ignoring defensive mechanics, stealing Turn Meter, and boosting his own stats by weakening opponents. His alternate form makes him incredibly durable and dangerous, even after taking lethal damage. He is a top priority build for PvP.

Strengths

  • Defense Ignoring: His default skill and AoE attack ignore Shield, Block Damage, and Unkillable buffs, allowing him to cut through the most protected enemies.
  • Turn Meter Theft: The 'Feather Volley' skill steals 20% of the Turn Meter from the entire enemy team, providing a massive speed advantage.
  • Stat Reduction: 'Thief's Mark' irreversibly steals 10% of the target's key stats, simultaneously empowering Nais himself.
  • Survivability and Form Change: The 'Radiant Savior' passive allows him to survive a fatal blow and switch to an alternate form with a new set of powerful abilities.
  • Control and Support in Alt Form: In his second form, he can apply irresistible Stun or Provoke debuffs, cleanse himself of all debuffs, and resurrect allies.

Weaknesses

  • Low Base Speed: 105 base Speed is very low for an attack champion, making him heavily reliant on high-quality gear and a speed booster.
  • Vulnerable to Control: Despite cleansing in his alt form, in his base form he can be easily locked down before he gets a turn.
  • Stat-Hungry Build: To be fully effective, he requires high Speed, Accuracy, and damage stats, demanding top-tier artifacts.

Where to use

Nais the Shadowthief is an absolute top-tier champion for all PvP content: Classic Arena (5.0), Tag Team Arena (5.0), Live Arena (5.0), and Siege. He also excels in the Sylvan Watchers Faction Wars (5.0). His performance in dungeons and against bosses is average (3.0), as his stat-stealing mechanic does not work on bosses, and his boss damage is not his primary strength.

Stats and gear

The main goal is to ensure Nais takes the first turn and deals massive damage. Stat priority: Speed (target 250+), Accuracy (target 350+), C. Rate (100%), C. DMG, and ATK/HP (for damage). Recommended sets: Savage, Cruel, Untouchable, Lethal, Stoneskin, or Merciless. Stoneskin provides extra protection at the start of the battle, while defense-ignoring sets amplify his already dangerous attacks.

Masteries and blessings

Masteries that boost damage and speed, such as Speedy Willpower and Skillmaster, are excellent for Nais. Bloodthirsty Prowess helps finish off weakened enemies. For blessings, the best choice is Crushing Rend for maximum defense ignore. Chainbreaker or Heavencast are also useful for increasing damage and control.

Tomes

Priority should be given to booking his 'Feather Volley' (A2) skill to reduce its cooldown. This allows him to steal Turn Meter and control the fight more often. Next is 'Thief's Mark' (A3) for increased damage. Skills in his alternate form can be booked last.

Verdict

Nais the Shadowthief is one of the strongest mythical champions for the Arena, capable of single-handedly turning the tide of battle. His form-switching and stat-stealing mechanics make him a unique and extremely dangerous opponent, though he requires significant investment in gear.
