Are you nuts? If these guys have been dropped by leeches outside the dungeon, they are going to be less than useless to us inside. At best, they soak a few HD of damage.
Then, they die.
Then, we have their blood on our hands.
If they insist on going along (it's their idea), Arien would not deny them... but there's a reason Yolanda summoned what amounts to a group of heroes, rather than send more nameless hunters to save her son.
Arn - Levitate and Cut down
Lin - Fly and Carry
Jar - Watch and FF prepared
Fin - Watch and prepare flute
Spa - Watch and Bow ready
Ody - Watch with True Seeing
Max - Watch with Axes ready
Kad - watch with Crossbow ready
If I have made the wrong assumption here, let me know please.
My understanding was that Arien and Lun would fly/levitate, cut down a victim, carry to a third person, have Jarenion cast. Drop the victims (Arien cuts down #3). We repeat that process, uses two castings.
