Slay the Spire 2 Omnislice Guide
Omnislice is an attack in Slay the Spire 2 that spreads damage across the battlefield. Instead of hitting every enemy directly, the card strikes one target first and then copies that damage to every other enemy. Because the card costs zero energy, it can easily fit into almost any turn.
This design makes Omnislice especially useful in fights with multiple enemies. A single attack can quickly turn into a full board hit without spending extra energy.
How Omnislice Works
Omnislice deals damage to one enemy, then deals the same amount of damage to every other enemy.
The key detail is that the damage applied to the first target determines how much damage spreads to the rest of the enemies.
Base version
Cost 0 energy
Deal 8 damage to one enemy
All other enemies take the same damage
Upgraded version
Deal 11 damage
All other enemies take the same damage
Because the attack costs zero energy, it is easy to include during almost any turn.
Why Omnislice Is Strong In Multi Enemy Fights
Omnislice becomes very efficient when facing several enemies. Instead of playing separate attacks for each target, the card spreads damage automatically.
Situations where the card performs well
Hallway fights with multiple enemies
Encounters with enemy groups
Turns where energy is limited
Since the card costs zero energy, it provides extra damage without reducing your ability to play other cards.
How Damage Scaling Works
Any bonus damage applied to the main hit will also increase the damage dealt to the other enemies. This means the card becomes stronger when combined with damage boosts.
Ways to increase its impact
Strength bonuses
Vulnerable on the target
Damage increasing relics
When the first hit becomes stronger, the spread damage also increases.
Why The Upgrade Is Valuable
The upgrade increases the base damage from 8 to 11. Since the damage spreads to every enemy, the upgrade effectively increases the total damage of the card by a large amount in multi enemy fights.
Benefits of upgrading
Higher single target damage
Higher spread damage to all enemies
Stronger performance in group fights
Because the damage spreads, the upgrade often provides more value than it appears at first.
Final Blurb
Omnislice is a flexible attack that spreads damage across enemy groups. By striking one target and copying the damage to others, it turns a simple hit into a multi enemy attack.
The zero energy cost makes it easy to play during almost any turn. In fights with several enemies, Omnislice can quickly chip down the entire group while still leaving energy available for other cards.
