The damage dealt by a block from this shield is 40 Poisondamage over time. This damage can be modified by increases and reductions to Chaos damage, Poison damage, and Ailment magnitude.
The Lycosidae Unique Shield now has "Blocking Damage Poisons the Enemy as though dealing 200 Base Chaos Damage" (previously 100). Existing versions of this item can be updated using a Divine Orb.
