Affinity & Aversion
Your hero pulls the board toward one element and pushes another away, so you see more of the first and less of the second from the opening rune. Thor draws Lightning and thins Earth, Skadi draws Frost and thins Fire, Sinmara draws Fire and thins Water, Freyr draws Earth and thins Frost.
In detail
Every element starts at a spawn weight of 1.0. Your hero's affinity adds 0.5 to their own element and their aversion subtracts 0.5 from another, so the affinity element spawns at 1.5 times a neutral rune and the averted one at 0.5 times. On a six-colour board that is 25% of new blocks for the affinity element, 8.3% for the averted one, and 16.7% for each of the rest. Focus charms stack on top additively, so an on-element Focus deepens an affinity, or claws part of an aversion back. Sun is the one element no hero has a relationship with.
