Hero Building Basics
Where to put your resources: which heroes make up each squad, what order to level their skills, who to star up first, and how to handle gear. Reference infographics are included at the bottom of each section — the text above them is the same info, just easier to read on a phone.
The Three Squads

Tank Mythic Gear Priority
Which piece, which hero, what order
Gear type priority, and why:
- Radar — get to 5 first. 30% less critical damage taken. Even if you don’t follow the exact chart order, prioritize 5 radar.
- Armor. Lowers critical hit chance taken by 15%.
- Guns. 10% damage boost — but only when countering.
- Chips. Overrated. 5% reduced damage taken, and only when countering.
Full order (1 = first). Columns follow the tank lineup:
| Gear | Kim | Stetmann | Williams | Murphy | Marshall |
|---|---|---|---|---|---|
| Radar | 1 | 2 | 3 | 4 | 5 |
| Armor | 6 | 7 | 8 | 9 | 10 |
| Gun | 11 | 19 | 12 | 20 | 15 |
| Chip | 13 | 16 | 14 | 18 | 17 |
Not running Williams and/or Stetmann? Send that second Radar to Murphy instead, or to whichever hero you actually field — whatever is more effective.
This is a general priority guide; it shifts a bit with your lineup, the season, and exclusive weapon priorities.
