I've noticed a few questions about how Brain Drain works, but I could never figure out something not mentioned so far:
How do you calculate the Will save? It just mentions that it has a Will save and that the information gained is the same as using Detect Thoughts. Is it the same save as Detect Thoughts? Or is it something like "10 + half your oracle level + your Charisma modifier"? Please help! I want to use this ability but if the save is something as small as a 1st level spell it would feel really underwhelming.
