However, Arbrut had managed to wrestle his tormentors away for a moment, and snarling lashed out. Falkor's prepared spell smashed into Arbrut and his snarl turned into a shaking howl of pain. Falkor felt temprarily weak...he hoped Arbrut did not utter such an inhuman shriek again, for it tiwsted something deep in the halfling's soul.
Hah! Right in the face again! The fireball will do 3d6+3 damage. No attack roll needed for proper spells, just remember the danger in castign them too close to an enemy. In this case, since you readied a spell, it will of course trigger while he is still far away

Arbrut seems shocked and afraid to be re-enacting history. Except this time, his weapon blow was turned aside by the force of the fireball, which went wide over Falkor's head. Arbrut's face twisted in fury and fear, however then something seemed to occur to the soldier. There were no restrainign hands aroudn him, for the explosion of the fireball had temporarily blown away the spirits.
There was a reverbarating laugh as Arbrut sank into the floor infront of Falkor, disappearing from view...
Good idea, sadly the items Arbrut carries are simply shostly versions of the ones he carried in life, and so won't conduct heat, etc. There's something interesting about that, which you might already have figured out because of what happened to the spirit's possessions... Unfortunately, not really much use right now, might be some other time.
Sadly, I'd already decided that area effect spells like fireball (being more powerful) would of course also carry the penalty of making Abrut's life temporarily easier, since his tormentors were all around him. The good news is, he's technically blind while in the floor. The bad news is...apparenatly he can smell out your soul, whatever that means! The good news is, you seem to have a companion getting more able all the time.
Anyway, your move.... and be careful, Arbrut is very wounded, but even a reduced ghost (like Arbrut) has some very nasty powers. Oh, I forgot to ask you, did you want to try out seeing the stats (like AC and hp) of your opponent(s) in this encounter? My preference is for narrative description only, but thought I'd try the other way to let you guys get a feel for it.
Let me know!
