Go forth and aid the weak!
Henzell says...
  1. Waist-deep pools of water. Moving through this stuff is gonna be really slow! All but Armataur, Ogre, Troll, Formicid, Grey draconian, Naga, Merfolk, Barachian, or Octopode players in shallow water will fumble melee attacks 37.5% of the time. Monsters will fumble their attack 1/4 of the time.
  2. Entering a shallow water tile is 60% slower for the player, exiting a shallow water tile is 60% slower for monsters.
