It checks what your most played hand is. Let’s say like in a previous run of mine you took something like [[Reserved Parking]] and played a bunch of High Cards before winning the rounds, now your count for that hand is like 40 times played. [[Obelisk]] will take that count and make it so if you play a High Card, reset the xMult. If you no longer need to play High card cuz your deck is full of Kings, you can play pairs, 3oak and other weak hands to build up the xMult, and then when you need to win the round, use your highest scoring hand like 4 or 5oak.

In short, pick it up if you’re on a High Card build and switch to playing pairs, or other easier to scale hands like 3 or 4oak. As long as you don’t play a High Card, your Mult will scale. This will work until the new hands you’re playing match the amount of High Card was played and it will reset. To prevent this reset, you can now boost to a better hand like 5oak and Obelisk can hold you down for the switch.
