Itemized Roles 10 roles

// Role assignment

For a given comp, three roles are assigned in a fixed order:

1. Carry. The comp's highest-rated ranged damage dealer. Between equal ratings, the higher-cost champion is selected, and a champion whose traits are active in the comp ranks above one whose traits are inactive.
2. Main Tank. The comp's highest-rated tank, by the same tie-break rules.
3. Support. One dedicated support. Ranged supports are preferred, since they can be positioned safely next to the carry; a melee support is selected instead only when its rating is clearly higher. When the comp has no ranged support at all, the comp's second-best tank is assigned as a Support Tank and holds the debuff auras.

// Item priority

Comps shown in the Trait Explorer's results and in the Comp Simulator's Roles & Positioning tab carry an "Item priority" label next to each assigned role. It is the recommended order for completing items before you have enough for every role. The order is determined by the comp's frontline:

• Three or more melee units: the carry is itemized first, then the Main Tank, then the support.
• Fewer than three melee units: the Main Tank is itemized first, then the carry, then the support.
• A defensive trait active at gold tier: the carries are itemized first and the aura tank last, since the trait keeps the frontline alive without dedicated tank items.

// Positioning

Every comp also gets recommended starting positions on your side of the board. The Team Builder's "Auto-position" button applies them to your current board, and the Comp Simulator's Roles & Positioning tab shows them for the core comp:

• The carry is placed in the bottom-left corner. Opposing players most often position their carries so that they end up on the right side of your board, so the left corner maximizes the distance to them.
• Ranged units of the carry's damage type are placed in the same corner, so their shred and burn debuffs land on the targets the carry is attacking. Ranged units of the other damage type are placed in the opposite corner.
• The front row is reserved for tanks. A Main Tank holding Gargoyle Stoneplate is placed alone at front-center; otherwise the tanks fill the front row toward the carry's side.
• Support tanks are placed on the carry's side so that their auras cover the enemies the carry is attacking. Melee supports are placed on the right edge.
• Melee units that are not tanks are placed in the third row, near the center. They enter the fight after the opening exchange instead of absorbing it.
