The reward for committing to gold. Five mana buys an enchantment that does nothing the turn it lands and asks something specific in return: every multicolored spell you cast afterward pings a single target for 2. That second clause carries the whole design, because it warps your spell base toward gold cards specifically, not merely toward two colors. A deck full of efficient monocolored spells leaves the enchantment inert; a deck that leans into multicolored payoffs turns each subsequent cast into a free Shock attached to a spell you wanted anyway. Because the damage hits any target, you choose each trigger: snap off a small creature with one cast, push it at a face with the next. The honest read is that the rate is slow and the trigger conditional, which keeps it out of the fair-removal conversation that one-mana burn dominates. What it offers instead is recurrence, an engine that compounds with every gold spell that follows rather than a single answer spent once. The constraint it pays you for is one of the more demanding ones, since "multicolored" is a narrower funnel than "red" or "instant or sorcery." The damage is incidental; the design statement is that gold-card density should be its own reward.
