ok i have a 13th level druid who is played like a biologist. he wants to learn about mostly creatures, especially dragons. now i was thinking that the only thing keeping him from being able to know as much as he can, is time. druids already do not incur any penalties for aging, but still die when their time has come. the wish i am trying to word would have the desired effect of not dying from old age. he can still be killed but no matter how long he lives, he will not die from being old. this stacked with the druids class ability means that esentially he will live forever without picking up those minuses to physical stats, and still gaining the bonuses to mental abilities. what scientist would want to have the opertunity to study forever, and see if their theories come into existance. he is not asking to be invonerable, not to die when his "time" is up. any suggestions? thanks ahead of time.
