Support (Position 4 / Position 5)
Utility roles who buy vision wards and sacrifice farm to enable teammates.
Supports (Position 4 soft support, Position 5 hard support) sacrifice personal farm to buy vision (observer wards, sentry wards), smoke of deceit, and utility items. Hard supports have the lowest gold income of any role. Support quality — vision control, stun timing, save spells — is frequently the differentiating factor between professional teams.
