Rune Duel
Defeat the 18-health sentinel with finite adjacent rune PAIRS. Sword pairs deal 2 plus TWICE stored focus, then spend it. Shield pairs block up to 4 of the next counter and turn blocked damage into focus. Heart pairs heal 3 (maximum 6). The sentinel previews counters in a repeating 2 / 3 / 0 / 4 rhythm. Every completed pair triggers that counter unless your strike wins. Plan parries around heavy attacks and preserve pairable runes.
