Companion Progression
Companions grow stronger alongside you through a deep companion progression system. Each companion can reach Level 60 and develops five core stats that define their combat effectiveness.
Stat System
Every companion has five stats that influence their performance:
- STR (Strength) - Increases damage dealt
- DEX (Dexterity) - Improves attack speed and hit chance
- CON (Constitution) - Boosts max stamina and stamina regeneration
- LUCK - Enhances critical hit chance and critical damage
- SPECIAL - Amplifies special ability effects and stamina capacity
Leveling & Stat Growth
Companions earn experience from combat and level up automatically. Each level grants 5 stat points. Some of these points are allocated automatically based on the companion's nature, while the rest can be assigned by you to customize their build. This flexible companion leveling system allows for diverse builds and strategies.
The XP required per level scales exponentially:
This means late levels are significantly harder to reach.
How Companions Gain Experience
Companion XP gain is determined by two factors when an enemy is defeated:
- Damage Contribution: XP scales directly with the percentage of damage your companion dealt to the enemy. If your companion dealt 60% of an enemy's health, they receive 60% of the base XP
- Last Hit Bonus: If your companion lands the killing blow, they receive a bonus +33% of base XP on top of their damage contribution
Base XP Formula: Base XP = 0.7 × Random(0.45-1.55) × (Enemy Level^1.1 + 2) × Level Difference Modifier × Total Companion Level Bonus × Guild Buff
This system rewards active companion combat participation. Companions that deal more damage level faster, and securing kills provides a significant XP boost. The base XP scales exponentially with enemy level, making higher-level enemies more valuable for companion training.
Scaling with Your Gear
Companion damage scales with three aspects of your equipped items:
- ilvl (Item Level) - The base level of an item
- Item Quality - Determined by Rarity and Quality upgrades
- Soul Level - Gained by leveling your items (requires an item to have a Soul)
As you equip higher ilvl gear, upgrade your items, and level them through combat, your companions automatically become stronger. This creates natural progression where your companions grow alongside your character's equipment improvements, making gear optimization crucial for companion power.
Guild buffs can also enhance companion performance, providing bonuses to damage, speed and range, or stamina regeneration based on your guild's active buffs.
Total Companion Level
Your Total Companion Level is the sum of all your companions' individual levels. This cumulative progression provides powerful account-wide benefits that make leveling additional companions increasingly rewarding.
Bonus Stat Points
Every 10 total companion levels grants 2 bonus stat points that can be allocated to any companion. For example, reaching 50 total companion levels provides 10 bonus stat points to distribute across your roster as you see fit.
Global XP Bonus
All companions gain bonus XP based on your total companion level. This bonus scales asymptotically toward a maximum of 125%, meaning each companion you level makes all future companion progression faster:
- 50 total levels: ~17.8% bonus XP
- 100 total levels: ~27.8% bonus XP
- 350 total levels: ~62.5% bonus XP
This system rewards investing in your entire companion roster. Guild buffs can further enhance companion XP gains by an additional 25%, stacking multiplicatively with your total companion level bonus.
Mentor System
Accelerate your companion training with the mentor system. Your active companion can mentor one lower-level companion, sharing 15% of earned XP to speed up their development. This unique companion mentoring mechanic rewards strategic roster management.
How It Works
- Select any owned companion that's lower level than your active companion as a mentee
- The mentee receives 15% of all XP earned by your active companion
- The active companion still receives full XP - mentoring doesn't reduce their gains
- Mentoring automatically stops if the mentee reaches the mentor's level
- Perfect for bringing new companions up to speed or balancing your roster
Strategic Benefits
The mentor system lets you efficiently level multiple companions without switching your active fighter. This is especially valuable when you unlock high-level companions but want to try earlier ones, or when building a balanced team for different combat scenarios.
