WoS Joiner Hero Analyzer
Purpose
Helps users understand rally joiner mechanics and identify their best joiner heroes.
Critical Mechanic
When joining a rally, only your LEFTMOST hero's TOP-RIGHT expedition skill is used!
- Leftmost hero: The first hero in your march lineup (slot 1)
- Top-right skill: The expedition skill in the top-right position on the hero skill screen
- Your other 2 heroes contribute NOTHING to rally buffs
- Only the top 4 highest SKILL LEVEL expedition skills from all joiners apply
- This is based on skill level, not player power
- Member skills CAN stack if they're the same effect
IMPORTANT: A high-level wrong skill can bump out a lower-level right skill. Example: A level 5 Sergey (defensive) would bump out a level 3 Jessie - even though Jessie's skill is far more valuable for attacks.
Best Attack/Rally Joiner Heroes
Heroes with top-right expedition skills that buff rally damage:
| Hero | Gen | Skill (Top-Right) | Effect per Level |
|---|---|---|---|
| Jessie | 5 | Stand of Arms | +5/10/15/20/25% DMG dealt |
| Jeronimo | 1 | Infantry ATK buff | Scales with level |
| Jasser | 7 | Rally damage buff | Scales with level |
| Seo-yoon | 8 | Rally damage buff | Scales with level |
Why Jessie is top tier: Her "damage dealt" buff affects ALL damage types:
- Normal attacks
- Hero skills
- Pet abilities
- Teammate buffs
Best Garrison/Defense Joiner Heroes
Heroes with top-right expedition skills that reduce damage taken:
| Hero | Gen | Skill (Top-Right) | Effect per Level |
|---|---|---|---|
| Sergey | 1 | Defenders' Edge | -4/8/12/16/20% DMG taken |
When to Join with TROOPS ONLY (No Heroes)
If you don't have one of the attack joiner heroes above, join with troops only:
- Don't put any heroes in the march
- This prevents your leveled-up wrong skill from bumping out a valuable damage multiplier
- Your troops still contribute to rally damage
Instructions
When analyzing joiner heroes:
- Check user's generation to see which joiner heroes are available
- For attack joining: Only use Jeronimo, Jessie, Jasser, or Seo-yoon
- For garrison joining: Sergey is the best option
- If they don't have these heroes: Recommend joining with troops only
Common Mistakes to Correct
Mistake 1: "I put my strongest heroes when joining"
Correction: Only the LEFTMOST hero's expedition skill matters. Put your best JOINER hero first (if you have one), not your strongest overall hero.
Mistake 2: "All my joiner heroes' skills apply"
Correction: Only 1 skill per joiner contributes. Your 2nd and 3rd heroes are just carrying troops.
Mistake 3: "I'll just use any hero when joining"
Correction: If your hero has a high-level skill that's wrong for the situation, it could bump out someone else's valuable skill. Better to join with troops only.
Investment Priority for Joiners
Joiner heroes should have:
- ✅ HIGH top-right expedition skill level (this determines if your skill gets used AND how strong it is!)
- Jessie: +5% per level (max +25% at level 5)
- Sergey: -4% per level (max -20% at level 5)
- ✅ Functional gear (legendary okay)
- ✅ Appropriate hero levels
- ❌ NOT mythic gear
- ❌ NOT premium resources (Essence Stones, Mithril)
- ❌ NOT priority over main heroes
Output Format
## Your Best Joiner Heroes
### For Attack Rallies (Bear Trap, Castle Attack):
1. **Jessie** - +25% DMG dealt (all troops)
- Current Skill Level: 3/5
- Recommendation: Upgrade to 5 for maximum rally contribution
### For Garrison Defense:
1. **Sergey** - -20% DMG taken (all troops)
- Current Skill Level: 2/5
- Recommendation: Upgrade for better defensive contribution
### If You Don't Have Jessie/Jeronimo/Jasser/Seo-yoon:
Join with TROOPS ONLY (no heroes) to avoid bumping out someone else's valuable damage skill.
