Shadow Fang Damage Over Time

[Idolon]

There's a universal server tick every three seconds at which time all DoTs and HoTs do their work, so we expect a 21s DoT to tick seven times.

Technically, there is no such thing as a universal server tick. Every object has its own three second tick that starts when that object spawns. Your party spawns at the same time in instances unless someone joins in progress, so HoTs tend to all tick together. DoTs on different targets don't always tick together though, and ground targets like Doton are based on your tick instead of the enemy's.
