Describe the bug. Be as specific as possible, images or short gifs/videos are welcome but save configuration files for later sections. Write a whole paragraph if needed, help us bug testers replicate your issue!
When using the Damage mechanic, the damage specified in the Damage mechanic is only applied to the mobs target, regardless if the ability hits someone else. This is particularly noticeable when using the projectile onHit metaskill. There is no hit sound, damage taken, nothing.

This also appears in the shoot mechanic as well, the damage field doesn't apply damage to the targets specified unless the target of the skill is the mobs target.

Example Configurations
Since this is a relatively large paste, I've highlighted *all* references to the damage mechanic that have been used with multiple targets.

There is a workaround for this, as it seems to be a worldguard related issue. Be sure to enable pvp in any region you intend to fight the boss in, however disable pvp on a world scope (multiverse, or anything else) and this issue will go away. Players will not be able to fight each other still.

Worldguard seems to treat the Damage mechanic as pvp damage, and thus gets blocked when pvp is set to deny.
