- Shrapnel Mine is a ground targeted skill. The mine trap lasts 20 sec.
- Excellent synergy with skills/traits that are more powerful if the target is afflicted with a condition (such as Radiant Power) due to the lengthy (20s) bleed it causes and its relatively short cooldown (20s).
- Mine now has direct damage when triggered, but no longer detonates instantly when thrown on an enemy. Triggers if enemy walks into or out of the radius.
