Envoy: Elves often have trouble relating to neighbors of other races, especially those with much shorter lifespans. As a result, some are trained in minor magics that are particularly useful when dealing with non-elves. Elves with this racial trait and an Intelligence score of 11 or higher gain the following spell-like abilities once per day: comprehend languages, detect magic, detect poison, and read magic. The caster level for these effects is equal to the elf's level. This racial trait replaces elven magic.
So I'm playing an elf antipaladin and would LOVE to have Read Magic twice per day, would I be allowed to choose the same level 0 spell again with my Elf Trait?
I see no reason to disallow it. But there is one trait (forgot which) that allows you to use one harmless cantrip three times per day. The problem is: I have found no explanation what harmless means. It could either mean a cantrip that is not used in an offensive manner or it could mean a cantrip that has a save with the (harmless) addition.
In the first way of reading it read magic would apply, in the second way it would not.
So it might be possible to get not only two but three uses out of just the one trait without needing the envoy.
Sure you can them both. Nothing suggest otherwise.
If you wanted a third use, the Magical Talet trait is an option.
Not sure, what the trait is that Umbranus refer to, but it seem to be the best option.
Wow yeah that'd be a nice one to have haha.
I now can't quite decide if I should use that trait for Read Magic or if I should take Touch of Fatigue since my character is an awakened undead paladin who is "Pestilence" in a 4 horsemen themed evil campaign...
Umbranus if you remember that trait, let me know! Thanks for your input guys!
