I'm not sure if its technical possible but here is a idea to make Ephemeral Weapons more interesting.
Why insteat of making them a random slayer, give the items the ability to change into the slayer of the monster you first hit with?
Example: Shoot/Hit a daemon they become Daemon Slayers. Shoot/Hit a troll they become a Repond Slayer. Just a thought.
With this even with the shorter life of these weapons, it can be interesting for people to get them.
