Thinking - Is this thing delaying to lure us in and if this is a solo it must be nasty.
With two minors, Simorai touches Buckthorn’s bow and Forges weapon. On the bow, he put a Lighting Signal (+11 lighting damage until end of encounter and as a free action (on a hit) Buckthorn can end the damage and daze the creature (save ends). On Forge’s weapon, he put a Radiant Signal (now does radiant damage until end of encounter(probably meaningless here) but on a hit Forge regains 6 hp; as a free action (on a hit) Forge can end the radiant damage and daze the creature (save ends) and in addition as part of the free action he can spend a healing surge +6).
For Simorai’s standard action, he ready’s an attack power. If the gargoyle moves and gets into melee range (before the gargoyle’s attack), Simorai will strike with Energy Theft. This is more for the effect than damage. The gargoyle gains vulnerable 5 to lighting damage and allies within 5 gain resist 5 to lighting damage (which probably won’t mean much, but Buckthorn’s and most of Sim’s attacks will do an extra 5 damage) until the end of the encounter.
As a free action Simorai attempts to parlay and says: Slave-dog of Acererk flee this place or face our wrath!
