Each class in Chrono Odyssey uses one or two unique resource systems that govern ability usage. These resources generate and deplete through different actions, creating distinct combat rhythms for each class. The four known resource types are Rage, Vigor, Mana, and Bloodlust.
Rage
Rage builds through dealing and receiving damage. It is an aggressive resource that rewards sustained combat engagement. Both the Swordsman and the Berserker use Rage, but their relationship with it differs. The Swordsman is a versatile melee fighter who grows stronger in prolonged combat through steady Rage generation. The Berserker is a high-risk, high-reward bruiser fueled by bloodshed, consuming Rage in explosive bursts.
The Berserker's Chain Blades, Twin Axes, and Battle Axe generate Rage at different rates. Choosing when to spend Rage on devastating abilities versus letting it build for ultimate attacks is a constant tactical decision. The Berserker's ultimate grants temporary full-Rage carnage with damage immunity.
Vigor
Vigor is a stamina-like resource that replenishes over time and through movement. The Ranger and Assassin both use Vigor as a primary resource. The Ranger's Bow, Crossbow, and Rapier all draw from Vigor for their hit-and-run kiting style with mobility-focused abilities. The Rapier specifically enables dashes, parries, and critical-hit stuns. The Ranger's ultimate ability zooms toward a target for a massive critical burst.
Vigor rewards active, mobile play. Staying in motion and maintaining offensive pressure generates Vigor faster than standing still. This pushes Vigor users toward the aggressive, evasive combat style the resource is designed to support.
Mana
Mana powers both offensive and supportive abilities for the Sorcerer and Paladin. The Sorcerer's three weapons serve distinct roles: Staff for destruction, Manasphere for time-based debuffs, and Grimoire for healing. The Paladin uses Mana differently across Lance & Shield (tanking), Halberd (DPS), and Mace & Shield (healing), making the Paladin a recommended class for beginners due to its flexibility.
Mana management separates effective casters from those who run dry at critical moments. Passive regeneration means Mana users can always contribute, but their strongest abilities require careful budgeting. Using the Chronotector's Temporal Isolation to freeze enemies during regeneration phases is a practical tactic.
Bloodlust
Bloodlust is an aggressive secondary resource unique to the Assassin, used alongside Vigor. It builds through critical hits and rapid strikes, rewarding the Assassin's burst-oriented playstyle. The Assassin's Sabre, Wrist Blades, and Musket each interact with Bloodlust differently, with close-range weapons generating it faster through rapid combos.
As a dual-resource class, the Assassin must track both Vigor and Bloodlust simultaneously. Vigor fuels mobility and basic attacks, while Bloodlust powers the stealthy burst combos that define the class. This creates the most complex resource management challenge of any class, fitting the Assassin's identity as a high-skill-ceiling option.
Resource interaction with weapon switching
The Dual Weapon Switching system interacts with class resources in important ways. Different weapons within a class generate and consume resources at different rates. Swapping to a weapon that generates your needed resource faster, then swapping back to spend it with a high-cost ability, is a legitimate combat optimization. This creates weapon-swap rotations that are resource-driven rather than purely damage-driven.
