Healer
Avoid healing diagonally across multiple ramp lips. If a DPS drops, move to the top or bottom of the same ramp instead of cutting across center and creating a second sight break.
Undermine | Compact four-ramp platform
The newest arena is a close-quarters level-control test. Its shallow ramps can break line of sight earlier than their height suggests, so teams need explicit top, bottom, left, and right calls.

The diagram is a positioning model, not a scale map. It highlights the cover, level changes, and rotation lanes that matter during combat.
A metal platform with one shallow ramp at each corner creates four level-change lanes and almost no conventional pillar reset.
Choose one side of the platform and keep the healer level with the likely kill target. Name a home ramp before the first displacement effect lands.
Avoid healing diagonally across multiple ramp lips. If a DPS drops, move to the top or bottom of the same ramp instead of cutting across center and creating a second sight break.
Intercept the next ramp exit rather than tracing a full loop. Knockbacks, grips, roots, and ports gain value whenever they change a target's level.
A player can look directly visible yet be unhealable because the ramp slope has already broken line of sight.
Avoid healing diagonally across multiple ramp lips. If a DPS drops, move to the top or bottom of the same ramp instead of cutting across center and creating a second sight break.
Pressure from the same platform edge as the healer and intercept the next ramp landing. Do not chase a full loop when the opposite exit offers a shorter swap.
Keep an escape ramp behind, not beneath, your position. Use instant casts while changing levels because the shallow lip can end a hard cast or healing lane early.
Close quarters reduce reconnect time.
Changing a target's level interrupts its support route.
Few durable pillars means mobile damage loses less to movement.
Top-left, bottom-right, platform, and floor are more useful than near or far.
The shallow ramp can block a heal before the model looks hidden.
Meet the target at its next ramp instead of tracing the platform perimeter.
