Dont say we dont love them guys in grey. The guards should really unlock more powers of their wands. One of them being a sort of distress signal to call nearby help. I think the unsummon fx would be a good beacon and look cool. Or the special fx that throws a red glyph upwards.

They can call for back-up already, unless something radical has been changed since I was in the Watch.

I think Khael means from adventurers.

how about.. *Yells* HELP!

Maybe some "fireworks" items?

>.> Perfect! Watchman calls for Urgent Backup... Hellball vfx!

give guards whistles then :P
