Ruler Sinon Universal Tower Defense Guide, How to Get & Build!

The QL update in Universal Tower Defense quietly introduced one of the strongest hill units the game has seen in a long time. Ruler Sinon, also known as Sharpshooter in her base form, stands out because of her extreme range, strong boss-marking passive, and flexible damage modes.

Many players underestimated her at first, but once fully built, she easily competes with top meta hill units. This guide breaks down how to obtain Ruler Sinon, how to evolve her, and why she is so powerful in late-game content. Also check out our Universal Tower Defense Codes & Tier List for more rewards!


How to Obtain Sinon (Sharpshooter)

To start, you need to get Sinon (Sharpshooter) from the banner. She is a high-rarity unit, so expect to spend some gems before pulling her. Once you have at least one copy, you can begin preparing her for evolution. After obtaining her:

  • Fuse extra mythic units into her to level her up faster
  • Aim for Level 70 before evolution
  • Put most upgrade points into damage to make takedown farming easier

She is a hill unit with limited placements, which already hints at her high value in team compositions.


Required Items to Evolve Sinon

Evolving Sinon into her stronger form is fairly simple compared to other top-tier units.

Here is what you need:

  • Sinon’s Glasses
  • 3,500 Takedowns on Sharpshooter

The glasses can be crafted directly using the Speed Craft feature, so you do not need to grind stages endlessly for materials. The main grind comes from collecting takedowns.


Best Way to Farm Takedowns

The fastest and most consistent method to farm takedowns is:

  • Play Act 1 repeatedly
  • Equip damage-focused relics
  • Avoid traits that slow down kill speed

Even though Ruler increases overall power, it can slow takedown progress. For farming, damage-focused setups work better until you reach the 3.5k requirement.

Once completed, Sinon gains a massive 50% damage boost, making her much stronger in all modes.


Best Trait for Ruler Sinon

The best trait for Sinon is Ruler.

Why Ruler is ideal:

  • Boosts overall performance
  • Works extremely well with her low placement count
  • Synergizes with her map-wide targeting

Other acceptable traits:

  • Eternal
  • Ethereal

Avoid traits that reduce kill speed while farming takedowns. Ruler is best applied after the grind is finished.


Ruler Sinon Skills and Passives Explained

Ruler Sinon has one of the most overloaded kits in Universal Tower Defense.

Precision Shot (Passive)

  • Targets the enemy with the highest HP on the entire map
  • Marks the target for 20 seconds
  • Marked enemies take increased damage from all sources
  • Applies burn damage
  • Long cooldown, but extremely impactful against bosses

Dual Range System

Sinon switches between two combat modes automatically:

Normal Range Mode

  • Higher damage output
  • Uses combat grenades

Sniper Range Mode

  • Activates when enemies are out of normal range
  • Infinite range across the path
  • Lower damage but constant pressure

Combat Grenade

  • Throws grenades every 15 seconds
  • Grenades stay on the path and explode
  • Deals bonus damage if enemies walk over them
  • Provides strong area control and support damage

Why Ruler Sinon Is Meta

At max upgrades, Ruler Sinon can:

  • Reach map-wide range
  • Deal extremely high single-target and AoE damage
  • Mark bosses to melt them faster
  • Switch modes automatically based on enemy position

She performs better than many older hill units and even rivals top-tier staples in Infinite and late-game content.


Ruler Sinon is not just a flashy unit with big numbers. She brings utility, boss control, and flexible damage that fits perfectly into modern Universal Tower Defense teams. While the takedown grind takes time, the payoff is absolutely worth it. If you manage to roll Ruler and fully evolve her, you will have one of the strongest hill units currently available, capable of carrying both Infinite runs and difficult stages with ease.
