HELM - AuroraFFXI/AuroraASB GitHub Wiki

There is a skill for each HELM activity. Increasing this skill gives you a higher chance of a "Critical Strike" when performing the activity. A Critical Strike will not decrease the Stamina of the Node, increasing the amount of items that can be obtained from it. Multiple Critical Strikes can occur on each Node. Level 0 has a 0% chance for a Critical Strike this increases to a 25% chance at level 100.

There is a custom GM command to check your HELM levels, Digging is included in this as well.
