Note: Ranar without shield could carry an axe in each hand, and using both axes together gives a +2 to parry (same as he’d get from his shield’s +2 defence bonus).
However, as the axes have a U parry, you can’t parry and attack with them in the same turn. Parrying with one and attacking with the other is possible, but then you won’t get the +2 and the off-hand one will be -4/-2 to attack/parry.
Getting the shield back will allow a Block defence and add +2 to all defences, but also penalises you by -2 on attacks if you get stuck in close combat for more than one turn.
