Notes

• Epidemic only applies up to 5 stacks of each condition.
• The new conditions applied are applied by you and based on your condition damage
  • The duration is still based off of the original stacks and is not increased by expertise
• Though it states all nearby foes, it is limited to 5 targets.
• Conditions are copied the moment the projectile reaches its intended target, allowing the caster to continue applying conditions until then.
• If the target of epidemic dies before a projectile reaches its target, conditions will not be copied.
• Invulnerable enemies in the way of projectiles will prevent conditions from being copied.
