Now I can't make my mind, because as cool and thematic as Shapechanger looks, I don't see much advantage on getting it. Maybe if it gave me some stealthy advantages (which my character DOESN'T have for RP reasons), but as is, it seems kinda meh. Can anyone sell me this one or is it not that great anyway?
Chameleon Skin, on the other hand, is much less thematic but seems to be way stronger mechanic wise. The question is: it gives me advantage to Hide, but I'm not sure if using hide would help me in stealth checks in general.
Shed Skin is cool and thematic too, but I don't see myself getting into the thick of battle. I could also use it to heal, but again, not sure if worth it...
Any contructive help will be appreciated, and THANKS in advance!
Are you saying you gave up the Tome and it's boost to your CHA, in exchange for the Unusual Ability?
I meant that, by comparison, my choice was way stronger than anything the other players chose. So I thought about getting a skill that would be similar to a lower rarity magic item, so I can get something that is cool and thematic, while not outshining the others in my group.
Well, I don't know anything about these abilities other than what you've written here, but given the info in your post I say you go for shed skin. You said it's cool and thematic, and the only snag is that you're not sure that it's worth it. BUT, you said the other players are happy with just +1 weapons so it sounds like there's no real need for you to perfectly optimize this choice. A little bit of extra self-healing for squishy class like a warlock hardly goes amiss.
You could go with either of them, I feel that 5th level you start to not need them and have more spells that let you overcome things. I would go with disguise self, more so if you are in a bar to blend in. Maybe make it a bit of RP and not tell the others you are a snakefolk and surprise things later on.
