When B added by a Ravage Action would cascade, instead, Upgrade 1 E/T (before N counterattack.)

Lands with 3 or more Invaders are Mining lands. In Mining lands: Disease and modifiers to Disease affect Ravage Actions as though they were Build Actions. During the Build Step, Build Cards cause Ravage Actions (instead of Build Actions).

Setup: Add 1 E in each land with no N. Add 1 Disease and 1 C in the highest-numbered land with a T Setup symbol.

After the Build Step, on each board: Choose a land with E. Upgrade 1 E there.

Setup: Remove the Stage II 'Coastal Lands' card before randomly choosing Stage II cards. Place the 'Salt Deposits' card in place of the 2nd Stage II card. (New Deck Order: 111-2S22-33333, where S is the Salt Deposits card. Escalation ignores S.)

Instead of Mining Boom (I), after the Build Step, on each board: Choose a land with E. Build there, then Upgrade 1 E. (Build normally in a Mining land.)

Setup and During the Explore Step: On boards with 3 or fewer B: Add +1 E in each land successfully explored. (Max. 2 lands per board per Explore Card.)
