Manzanita said:OOC: Do the githyanki and githzerai look any different? Iggy attempts a spellcraft check on each potion (1 minute each), DC 25, to identify them. He mostly succeeds.
SRD said:Identifying Potions
In addition to the standard methods of identification, PCs can sample from each container they find to attempt to determine the nature of the liquid inside. An experienced character learns to identify potions by memory—for example, the last time she tasted a liquid that reminded her of almonds, it turned out to be a potion of cure moderate wounds.
