Swear your loyalty to the queen of chromatic dragons, and she might just bless you with her form

-You manifest the Mask of the Dragon Queen, a draconic mask wearing a crown styalized after the five types of chromatic dragons
-You can split the mask into the red, green, blue, black, and white masks and re-combine them by thinking about it, unless they are in use.
-If you put on one of the singular masks, it melds to your face and you transform into an anthro dragoness (m2f in you're male) of the matching colour with the features of your choosing (frills, breast size, ect.)
-If you put on the complete mask, it drips down your body and transforms you into Tiamat, the 5 headed Queen of chromatic dragons (m2f if you're male) as either an anthro or feral with your prefered features.
-As Tiamat, you've only got one mind, but you can see/hear/smell/taste and sense touch out of all 5 heads at once.
-Only you can see the changes unless you allow others to see them.
-If you allow others to see the changes, they can also use the masks
-Tiamat can change people into dragons of either gender with a kiss, they change into the form they wish to take
-If the person to be kissed consents to it, this kiss can turn them into an obedient kobold drone instead, in which case, Tiamat decides the form. (drone in mind only, a normal kobald otherwise)
-The mask's effects can be ended at any time, you just pull on your muzzle (the center red head as Tiamat) with the intent to remove the mask.You'll also change back when you sleep
-People changed by Tiamat change back when they want to, or when Tiamat changes back, which ever comes first, unless they're a kobold in which case only Tiamat's wish or her reverting will change them back.
