Darkmoon card question

Hello,
I have 2 questions regarding darkmoon trinkets.
Can you equip 2 darkmoon trinkets from different kind at the same time. Lets say Berserker and Death together.
My second question is what are the best darkoom cards for a warlock?

Thanks

You can equip two different ones. If the two different cards have the same "equip" effect they will share a cooldown.

Can you define "the same "equip" effect "
I was thinking of using those two mentioned above together Berserker and Death as a starting gear.

You can equip two different greatness cards but the cooldown will be shared.

In your case, though, berserker and death should be compatible.

Thank you very much. I was just wondering then if those are appropriate for a caster ? I am not 100 % sure if the stats affect spell crit and dmg.
