Just a few alterations to existing items:
Berserker’s Blade
-Activating this weapon doubles the effect of attacking aggressively, from +1 to hit and -2 AC, to +2 to hit and -4 AC. Additionally, an extra +2 will be added to the damage roll.
(This comes from me re-reading John’s house rules. I also thought extra damage fit the weapon better, as a payoff for the AC decrease.)
Healing Salve
This paste can be applied to a wound out of combat. Application takes a turn, allowing for proper dressing and the salve to soak into the skin. Each application heals 1d4+1 HP. Additionally, it Slows Poison as if cast by a second level cleric. Only one application may be allowed per day.
(This is to make the item a little less convoluted, and a little more useful.)
