Wondrous Item, Artifact, Weapon (Light Hammer), Requires Attunement
You have a +1 bonus to attack and damage rolls made with this magic weapon.
This weapon possesses 3 charges. As an action, the wielder can expend the use of a charge in order to cast one of the following spells: Detect Magic, Dispel Magic, Remove Curse.
On a hit, with this weapon, the target takes 1d4 bludgeoning damage (plus STR modifier). If Keening is also equipped, and its ability, Keening's Sting, was used; on a hit, add the drained ability to your max until a long rest is completed. (In the event of multiple hits, from either/both weapons, the benefit does not stack. Only one drain from Keening's Sting can be applied to the wielder's ability scores. If a new one is used, the previous is lost.)
If attuned and wielded without Wraithguard equipped, the wielder must make a DC 17 Constitution Save. On a failure, the wielder instantly drops to 0 HP, is considered unconscious, but does not make death saves. On a success, the wielder takes 2d10 damage. This save repeats every minute the wielder continues to wield Sunder without Wraithguard.
If all three of Kagrenac's Tools are equipped, their bonuses all improve from +1 to +3.
Proficiency with a mace allows you to add your proficiency bonus to the attack roll for any attack you make with it.
