Nudge that ceiling mob loose!
If you can get a friend with a non-targeted area-effect attack to join in the mission, you may be able to get it dealt with quicker than waiting for a GM.
Agreement on how nice it would be to have a /mobunstuck command, though.
Somtimes you can also summon pets fery close to the side and they will appear outside the wall and attack the foe for you.
IIRC there was talk about a new upcoming feature that shows the last few mobs on a map once the total is below a certain percentage remaining.. it'd be nice to have a "pull" command for them as well.
In my experience, as far as the caves are concerned, letting the foe aggro to you and then leaving his range will make him jump back into the "playable area", but it doesn't quite work for square rooms like in an office or warehouse.
This is also one of the actual moments when self destruct comes in handy too, we've had a few times when this has happened and damage aura's and the like are either unavailable or insufficient.
Stand where he can hit you to confirm, go boom, several team members can repeat if necessary to finish the job.
Nukes and the like work too if your less suicidally inclined.
The pellet with the poisons in the Vessel with the Pessel, the Chalice from the Palace has the brew that is true...
Several times in recent missions on both the CoH and CoV side, whether solo or in a group, I've had this occasional nagging problem with one enemy being "stuck" either in the ceiling or just behind a cave wall, where any attempts at attacking him gave a "target blocked" error, but he could target the players just fine.
While it is possible to "fix" this by resetting a mission, that's not a choice option when it's a "clear all enemies" mission, and he's the last one you find, up in the ceiling of a 2-story warehouse. Nor is it a good option any time it happens three or four floors into a large, multi-level mission.
Would it be possible to create a user command that would allow us to nudge these elusive targets into target-ability? Last time I got this, I was able to get a GM to release the stuck mob, but it's rather time consuming standing around waiting for a GM to shake the guy loose.
Suggested command names:
/mobstuck
/targetstuck
/nudgenpc
Or something along those lines, to un-stick the stuck character you need to defeat.
