Consume Trait

You’ve developed the skills necessary to not only adapt forms from the creatures you eat but also extract and use racial aspects. You gain the following benefits:

•  When you consume a creature (that is not an undead or a construct) with your Devouring Mass trait you can choose up to 1 racial feature which that creature had. That feature must not rely on spellcasting ability, legendary actions, legendary Resistances, or lair actions. (At DM's discretion)
• You may know as many traits up to your constitution modifier (minimum 1). If you wish to use a trait you must attune to that trait. Each trait takes a long rest to attune and an attunement slot. 
• You may use these traits as the creature you stole it from did with the same action cost.
