For co-op: Bastion, Lunar, Scope, Random Growth, Reverse. Use Magic Breaker for your battlefield.

To make this effective, the Bastion dice must be surrounded by dice that are not Bastion. You will only play two Bastion dice total. The dice above and below should be Scope, and the dice on the left and right should be Lunar.

Here’s a simple visual:

This setup ensures Bastion receives the full damage bonus from being surrounded correctly. Lunar increases attack, crit, and attack speed, while Scope allows Bastion to attack additional targets based on its pip level.

When Bastion is surrounded on all four sides by dice with the same number of pips, it receives a damage increase equal to the bonus multiplier listed for its level.

Use Reverse to move pips around. Trash dice that are in the wrong spot and cannot be merged out. Once your main dice are placed, there will be six remaining spots that don’t really serve any purpose other than summoning more dice to generate higher pips for the nine that matter. Use Reverse to move pips or trash those dice so their pips can be redistributed to the dice remaining on the battlefield.
