The Wrenmarc is the most militant of the disciplines, combining their soulspells and weapons or armour to great effect. They are the first line of defense against the elven swarm that comes from the tangles.
Those with defensive soulspells infuse their armour and are usually able to cast in armour; while offensive soulspells channel pure energy to their weapons, allowing them to cut right through armour. As such, the Wrenmarc usually serve as officers and champions during conflicts.
Unfortunately those with the appropriate soulspells are quite rare (thought not as rare as spellweavers) and only a handful can be committed to any one battle. They are marked by their gold torc that they wear around their necks.
