Snake Eater

You have learned the art of catching and consuming snakes.'

Whenever you are outdoors, so long as its reasonable to assume that wildlife exists in this area, you may make a Survival check with a DC dictated by your GM. On a success, you are aware of any snake or snake-like entities, and this success extends to trapping or catching a number of snakes equal to a [roll]1d4[/roll] roll plus your proficiency bonus.

Each individual snake caught this way can be consumed, healing you - and only you - for 3 + your Wisdom modifier + your proficiency bonus HP. 

You may use this ability twice per long rest. After a long rest, any and all snakes you've acquired in this way become spoiled, losing its curative effects.
