Each lochos's attack is pushed successively through the enemy's shield, strength and willpower values, and the depths reached are compared.
How it works
Each engaged lochos totals its Spear value (with Arete, momentum, depth, disarray, othismos modifiers) and applies it to the enemy Shield value (with gaps, momentum, terrain, ground-given modifiers). Any excess passes to the Strength value, and any further excess to the Arete Threshold. Both sides' penetration levels (none, shield, strength, threshold) are cross-referenced on the Melee Resolution Chart; exceeding the threshold breaks the lochos automatically.
if the Spear value exceeds the shield value, the Shieldwall is considered “Penetrated”. Any excess of the spear value number is then applied to the Strength value number, if this is also exceeded, any remaining number is applied to the Arete threshold number
