Scan

Command: scan <monster>
The scan command is a quick way to check on the relative condition of an opponent. It is usable both in and out of combat. Scan <target> will scan a specific target, while if no target is specified, it checks whoever you're attacking. The diagnostics skill is required to make make a good judgement.
There is an endurance point cost for use of scan and diagnostics. The higher the training in diagnostics, the lower the cost.

Notes:

With the per highbie advantage, you can use scan without the need for diagnostics.
