/* Note: OSI has a bug where the last "tick" is at 0 seconds and never happens.
* Example: 100SS -> 39s, 9 ticks, buff icon disappears with 3s left.
* 5.5, 5, 5, 5, 4, 3.5, 3, 3, 2 -> off.
*
* On ModernUO: 100SS -> 34s, 10 ticks
* We opt for the last tick at 1 second, so the duration is 1 second longer than it needs to be.
