I'm making a Kitsune character, and I want her to have the ability to disguise herself as other people.
To do this, I can either take a feat in Realistic Likeness ...
You can precisely mimic the physical features of any individual you have encountered. When you use your racial change shape ability, you can attempt to take the form of an individual, granting you a +10 circumstance bonus on Disguise checks made to fool others with your impersonation.
You make yourself – including clothing, armor, weapons, and equipment – look different. You can seem 1 foot shorter or taller, thin, fat, or in between. You cannot change your creature type (although you can appear as another subtype). Otherwise, the extent of the apparent change is up to you. You could add or obscure a minor feature or look like an entirely different person or gender.
The spell does not provide the abilities or mannerisms of the chosen form, nor does it alter the perceived tactile (touch) or audible (sound) properties of you or your equipment. If you use this spell to create a disguise, you get a +10 bonus on the Disguise check. A creature that interacts with the glamer gets a Will save to recognize it as an illusion.
So far the differences I can spot are:
- Realistic Likeness can be cast as many times as you want, while Disguise Self can only be cast twice per day (as per Magical Tail)
- Realistic Likeness can only let me look like people I have already met, whereas Disguise Self can make me look like whoever I want.
Another useful thing is that taking Magical Tail lets me get more useful spells sooner rather than later, like Charm Person or Invisibility if I decide to go that route.
Are there any other important differences between the two?
The character is a Bard, if it helps.
