I would like to have my players contend with a monster that they aren't quite strong enough to defeat. One option available to them after doing some research would be to get certain weapons in order to deal some bonus damage. For the sake of discussion, let's say they have to slay a dragon (which already exists in the handbooks) and that dragons in my campaign setting are weak to a certain type of crystal. What would be a good way to implement this? These are the ideas I've come up with so far:
- Give the weapons a small aura that makes dragons vulnerable to physical damage. There seems to be a precedent with paladins creating vulnerabilities: Multiple Sources of Damage against a single vulnerability
- Give the weapons a small aura that makes dragons vulnerable to crystal. Basically the same as #1, but doesn't enhance other physical attacks.
- Rewrite any dragon entries the players fight to have Vulnerable Crystal 5
- Give the weapon bonus damage against monsters with the chosen keyword: Trigger (Free action * At-will): You hit a dragon. Effect: Deal 1d6 bonus damage.
