Regent Overview

Regent is a new character in Slay the Spire 2 who fights using Stars, minions, and a growing signature weapon. This character focuses on resource management and increasing power over multiple turns. Stars are a special resource separate from energy, and they do not disappear between turns.
Some cards generate Stars, while others spend Stars as a cost. You need to save Stars across turns for a huge combo. Make sure to turn 1-3 to generate Stars and then turn 4+ to spend them for massive attacks or effects.
How to Play Regent

Salvage Blade is a signature weapon of Regent that costs 2 energy and deals around 10 damage. This weapon stays in your hand until used because it has Retain. Some cards have the Forge keyword, and when you use it, the weapon appears in your hand.
Its damage permanently increases when you use Forge. The Regent can transform cards into minions that provide block, attack, and special effects. Below are the steps for the effective turn in combat while playing as a Regent.
- Generate Stars and resources at the beginning.
- Use Forge to boost the effectiveness of Sovereign Blade.
- Create minions and deliver a massive finishing turn.
- Early turns feel very weak, but the late turns deal massive damage.
Sovereign Blade Deck Build

The Sovereign Blade deck build focuses on forging and scaling the Regent’s signature weapon till it deals massive damage in combat. Many Regent cards have Forge that increases the Blade’s damage for the rest of the fight.
The possible way to play this character is to play Forge cards for several turns. The Blade keeps gaining damage, so make sure to attack for huge burst damage when ready. The blade can deal 40-50 damage per hit or more after only 3-4 Forge activations. This build has slow early fights and depends heavily on drawing Forge cards.
Core Cards

Choosing the best cards is essential to eliminate the enemies quickly. Use the card that complements Forge to make your weapon more powerful. Below are the best cards that we recommend using for this Sovereign Blade Build.
- Summon Forth: Forge 8. Pulls Sovereign Blade into your hand from anywhere. This crucial support card allows you to use the Blade when it’s strong.
- Wrought in War: Allows you to attack, which adds Forge while dealing damage. It replaces basic Strike cards in the deck, allowing you to build Blade damage naturally while attacking.
- Conqueror: Grants a small Forge bonus and doubles Sovereign Blade damage on the turn.
- The Smith: This is a very expensive card because it adds a huge Forge around 30 in one turn.
- Parry: Grants Block whenever you play Sovereign Blade, making it useful because Blade costs 2 energy.
- Bulwark: Allows you to gain 13 Block and 10 Forge.
- Furnace: Get 4 Forge at the start of your turn, requiring enough time to build up.
- Seeking Edge: Grants 7 Forge to let your Sovereign Blade deal damage to all enemies.
Too many cards means fewer Forge activations and slower scaling. You must stack Forge and attack once the damage is huge.
Relics
The Fencing Manual is the best relic to choose for this Sovereign Blade Build. It grants 10 Forge at the start of each combat. Make sure to create extra Energy to balance the blade with Forging.
This relic makes the blade more effective and playable from the starting turns in combat. Use Falling Star and Gamma Blast to apply Vulnerable on a single turn.
Star Deck Build

The Star Deck build in Slay the Spire 2 focuses on generating and storing large amounts of Stars. You spend them in one huge combo turn for massive damage. Use this setup to gather Stars and use them in one explosive turn.
Star decks can die early if they scale too slowly, so having the early damage cards and basic block tools. This setup needs defense early while saving Stars and requires proper timing.
How Star Deck Build Works

The Regent has a special resource called Stars that are separate from energy in Slay the Spire 2. These stars do not disappear between turns and don’t have a maximum cap. The gameplay strategy should be to generate Stars for several turns.
You need to save them rather than spending immediately. You need to use multiple Star-cost cards in one explosive turn, allowing you to create powerful combo turns.
Early Cards

Here are the best early key cards for the Star Deck build in Slay the Spire 2.
- Gather Light: Gain 7 Block and Stars.
- Hidden Cache: Gain 1 Star immediately and more next turn, helping you start building your Star resource pool.
- Solar Strike: Deal 8 damage and gain Stars
- Convergence: Next turn, gain energy and stars. Retain your Hand this turn.
- Shining Strike: Allows you to deal damage and generates about 2 Stars each time it’s played. You can place it back on top of the draw pile.
Core Key Cards

Here are the potential Key Cards for the Star Deck build in Slay the Spire 2.
- Alignment: Converts Stars into normal energy and combines with Star generators like Venerate.
- Cloak of Stars: Gain 7 Block to help save Energy for bigger combos.
- Dying Star: Deal 9 damage to all enemies. All enemies lose 9 Strength this turn.
- Gamma Blast: Deals 13 damage and applies 2 Weak, along with the Apply 2 Vulnerable. Consider this the better version of Falling Star.
- Genesis: At the start of your turn, gain Stars. This allows you to repeatedly play expensive Star cards like seven stars and astral pulse.
- Reflect: Gain 17 Block and blocked attack damage is reflected to your attacker this turn.

Relics

Here are the best relics for the Star Deck build in Slay the Spire 2.

Avoid spending Stars randomly, stockpile Stars, and use them when you have multiple payoff cards. The common mistake that you make is taking too many Star generators. If you only generate Stars, you can never convert them into damage. Make sure your deck has early damage cards and basic block tools.
