Normally, Frozen Orb expires when
- It had ticked 20 times (24 with Everlasting Frost)
- It had been spawned for 15 seconds
Now, it expires after 10 seconds (12 with Everlasting Frost). This means that you lose ticks if you cast it from range. At 40 yards with Everlasting Frost, it will tick 21 times instead of 24.
