It took about 7 games for me to discover this. Whereas perhaps others discovered it much sooner? In the "earlier" part of the game when the board is more open, creating a destructive "blow-back" river is very fun and dangerous (for all players). So manipulating this feels like the table equivalent of that ouiji movement across a table.
Below I sent the River against the Green Sage and then "dammed" it up creating a wall which felt really clever discovering this tactic, by blocking one end with a wind stone then the other with an earth stone:
Since then, the tactic has been refined even more with optimal variants from this initial discovery, I can say with a lot of satisfaction!
In the above, of course the sage can easily escape but it was the discovery that was great and I am still discovering so much more about this game.
Yes but you can still play adjacent to it and move 2.
I think the main point was that the huge river line couldn't easily be returned to sender.
Yes, exactly. I was pointing out the exact moment I realised I could "block" a river and cause the other Sage to expend stones to change the river back if they received the correct stones or wishes to use their turn that way - instead of the previous "tug of war". Since then I have block a river more truly as well as chopped a river into segments and even sent hence two rivers against a Sage and so forth!
There is sometimes that "Street Fighter II / Killer Instinct": C-C-C-c-ccc Ultraaa Cooombo!!! about Element moves!
River really does move fast whereas mountain ranges creep and build in strength through the game.
