Hydroid Augment idea

For Tidal surge, make it create waves on enemies that converge on the player as they swim, grouping up enemies

I'd have it scale with strength for amount of waves per use of the ability, scaling with range of course to determine the range of how far the waves can pull, the duration would determine how long they'll pull for, similar to how long you can go for when you use the ability.

The name would be something like Coalescent/Coalescing Tides or Tidal Estuary.
