I was thinking about how HeroQuest and other similar dungeon crawlers are essentially board game versions of Tactical RPGs, and those sorts of games more often than not have an option to have one of your units guard and make no other action, and this idea occurred to me.
In addition to Attack, Cast, Search (Treasure, Trap or Secret Door), and Disarm, a Hero may choose to Guard as their action in a turn.
Choosing to Guard results in rolling +1 defence dice when a Hero is attacked until their next turn. If they have a shield equipped, Guard is +2 in defence dice.
