Hello everyone,
i have a question can i exchange +12 weapon for another at BoM?(so far pretty sure i can) And if so does the +enchant stays on or will be removed after exchange? thx for info

Confirmed - enchant will stay.

I have another question - kinda associated with the one above: how to get  a regular+12 weapon in the first place? I picked up from mobs 3 times 'santa box'. After opening received 3 times coupon to exchange for shadow weapon? Is it just me being unlucky to obtain shadow (that lasts 4h) rather than regular or is it obtainable in different way (i.e. rudolf can give it after reaching 100% of food)?

You need to drop Santa's Gift Box - Jackpot in order to get +12 regular weapon or get Weapon exchange coupon - Jackpot from regular Santa's Gift Box. In general you need to be extremely lucky.
