I've had several characters give poison damage when another character has applied poison to their weapon
Eg. Angharad (rogue Darkweaver) applies poison to her bow, shoots wolf wolf dies of piercing damage
Alaw (Sun Cleric) shoots other wolf with crossbow misses
Alwena attacks wolf with firebolt wolf sustains fire and poison damage
Anwyn attacks wolf with Scimitar wolf sustains slashing damage
Alaw attacks wolf with scorching ray, wolf sustain fire and poison damage.
I will email with a save
