Weakness
Every foe has elements it cannot stand. Match one of those runes and the hit lands harder than it should. Tap a foe's name to see what they are weak to.
In detail
A match against an element the enemy is weak to deals 1.25 times damage, or 25% more, by default. Individual enemies can carry their own multiplier per element, so some weaknesses bite harder than others. The orange WEAK! popup at the match site is the confirmation.
