Read again, macgawel. creatures get +1 | +1 even when not flooded. Stackable buffs = the sh!t.
That's what I've understood.
But I'm not convinced by a mere +1/+1 bonus, compared to the no-attack effect.
Even with the boost, the shard seems more interesting with others quanta (Fractal, scorpions, even sundial) than with Water....
