BloodlustA 2-handed weapon that seeks a bloodlust.
Grants an ability like step up.
+1 <2-handed weapon>. Any Time a creature [friend or foe] drops below 0 hit points, if the weilder is within a 5 foot step of it, he must move within striking distance if able, and make a killing blow. If the weilder kills the creature, he gets the effects of Deathknell. Wielder may make a Will save to avoid this ability. DC 15+Level of the wielder.
1.) Does this free movement count against you? What if you have already moved/5ft Stepped this round? This part is very confusing as it sounds like they must start out within 5ft, (that is they are already adjacent), but then it stipulates you must move into striking distance. The only way I would see this mattering is with a Reach Weapon, but then they normally wouldn't trigger the ability at all as they wouldn't start out 5ft away. The one major exception is against your own allies!!! Also note, Deathknell, being a [Death] effect, is going to devastate your parties wealth as neither Breath of Life or Raise Dead can bring them back.
2.) Does the dying creature also gain a Save as per Deathknell?
3.) Not sure it matters, but does it have to be a weapon that requires two hands to wield (such as a Greatsword), or one tat could be wielded with one or two hands, (such as a Longsword).
Suggestion: remove the distance and replace it with Threatening. That way a Longspear would be within 10ft where they can already hit the target, while a Greatsword would be 5ft, and neither would need to move at all. Secondarily, I'd probably change it so that you only risk attacking your allies if you fail with a Nat 1 or something.
GenocideA <Weapon> Borne of Rage against the world.
The Weapon Has a Demi-God of Rage bound to it. Its not intelligent, but it is a Living Weapon. It is a +1 Adamantine weapon that gains +1 hit and damage vs a creature type it has killed within the last 48 hours. This resets if you kill another creature type. Thier is no limit to the Bonus.
1.) What type of bonus is the +1 to Attack & Damage? What does it stack with? Does it increase the weapons Magical Enhancement bonus instead, and if so does that mean it can overcome more types of DR?
2.) Are we assuming that Creature Type is referring to the Ranger Favored Enemy list?
3.) What happens when someone else picks it up after it's got some juice?
Suggestion: Firstly, I'd simplify this by just basing it off of the Deadly Juggernaut spell, which both reasonably limits the bonus granted and what type of targets count. Boosting the duration to 48 hours by restricting it to specific creature types is a pretty decent balance in most cases, I think. (playtest needed). I might even rule that ANY kill made by the character resets it, not just one with the weapon, so you could not just swap to a dagger to get the finishing blow after building up Genocide's bonus.
