Strategic Build Recommendations

Support-Focused Build (Hunter Path)

Focus on Way of Artemis nodes to maximize team critical damage and Lethal Injury application. Perfect for teams with multiple DPS characters.

Aggressive DPS Build (Warrior Path)

Prioritize Way of Ares for maximum personal damage and team damage buffs. Ideal when Kassandra serves as primary damage dealer.

Synergy Build (Assassin Path)

Emphasize Way of Nyx for Assassination mechanics and team coordination. Best with other Assassin-type characters like Ezio.

Team Composition Synergies

With Ezio: Perfect Assassin’s Creed collaboration synergy, maximizing Assassination triggers and coordinated attacks.

Mixed Afflatus Teams: Kassandra’s Force Field effects benefit all allies regardless of their Afflatus type.

Critical-Focused Teams: Hunter path provides substantial critical rate and critical damage bonuses.

Resource Management Strategy

Kassandra gains 5 ability points through Insight. Use ability points to unlock abilities from the Hunter, Warrior, and Assassin branches starting from the bottom of the tree. Once a branch is selected, you must acquire all abilities from that branch before you can activate other branches.

This limitation creates meaningful decision-making: commit to a playstyle or spread points for versatility.
