Weapon does a Poison variant of the Burn thing the Thunder Lord items from last week do, except instead of a toggle, it has a trigger if the enemy is Burned, Bleeding, or Poisoned.

If the foe is under one of those effects, AND you did an attack that round that would have attempted the Poison (so a weapon attack or a skill/spell that matches the damage type/element of the weapon), then you'll replenish (10 * 0.85 * MagMult)% Melee in SP.
MagMult is 0.75 if the weapon is in Magic mode, 1 otherwise.

The shield is kind of like the Umazen Apsis/Emancipator's Radiance. While equipped, it gives a +20 potence to any and all status effects that are flagged as doing damage. So burn, poison, bleed, etc.
