Slay The Spire 2 Flanking Guide: How The Card Works
Flanking in Slay the Spire 2 is a Silent skill that causes an enemy to take double damage from other players for the rest of the turn. Flanking is mainly designed for co op runs, where teammates can take advantage of the doubled damage to burst down enemies extremely quickly.
What Flanking Does In Slay The Spire 2
Flanking is an Uncommon Silent skill card that costs 2 energy.
When played, it applies an effect that causes the targeted enemy to take double damage from attacks made by other players during the same turn.
This means the Silent who plays the card does not benefit from the damage increase. Instead, the bonus is applied to teammates.
The upgraded version of the card simply reduces the cost from 2 energy to 1 energy, making it much easier to use during combo turns.
Why Flanking Is Strong In Co Op
Flanking becomes extremely powerful when playing multiplayer runs.
Because the effect doubles damage from teammates, coordinated turns can deal huge amounts of damage very quickly. If multiple players attack the same enemy after Flanking is used, the damage can add up fast.
In some cases, several players attacking during the same turn can remove large chunks of boss health or eliminate elites immediately.
This makes Flanking one of the strongest team support cards available to the Silent in co op runs.
How Flanking Damage Scaling Works
The card multiplies incoming damage from teammates.
For example, if another player deals 20 damage to the affected enemy, the attack instead deals 40 damage. If several players attack, the doubled damage applies to each of those attacks.
Because of this, Flanking works best when teammates have high damage attacks ready to play during the same turn.
The more attacks that hit the target after Flanking is used, the more value the card provides.
Tips For Using Flanking
Use Flanking before teammates begin their attacks
Target enemies that will receive multiple attacks in the same turn
Save the card for elite or boss fights where burst damage matters
Upgrade the card early to reduce the energy cost
Coordinated teams can use Flanking to create extremely strong burst turns.
Final Blurb
Flanking gives the Silent a powerful support option in Slay the Spire 2 multiplayer runs. By doubling the damage dealt by teammates for a turn, the card enables coordinated burst attacks that can quickly eliminate dangerous enemies. When timed correctly during a team damage turn, Flanking can dramatically shorten difficult fights.
