I think it would be much better if the dimensional stability was not only affected by placement of Illuvials on the board but also time.
Soon as you land on the board the stability is decreasing. This makes the whole encounter so much more suspenseful. You’re not just battling the opponents but racing against time.
Otherwise I just feel like it’s too chill. PVC should be more suspenseful and not just rely on the strategy of your placement but also your availability to act quickly, assembling your team and choosing the right placement.
Makes it so much more rewarding too when you pull it off.
