Editing Age of Sigmar/Tactics/Edition 1.2/Idoneth Deepkin (section)

===Battle Traits===
*'''Forgotten Nightmares:''' Enemy units can only target your closest unit with Missile Weapons. Keeps your Heroes safe from shooting, though not from magic. Also note that you can use allies to shield your Deepkin with this.

*'''Tides of Death:''' Each round, you get a different ability. After the fourth, it cycles back to 1.
*#'''Low Tide:'''  Your units count as being in cover. Helps you advance without making you scramble to terrain.
*#'''Flood Tide:''' After running, your units can either shoot or charge (but not both).
*#'''High Tide:''' Units with this trait fight before everyone else in melee. Also, there's a bunch of abilities that activate during this turn.
*#'''Ebb Tide:''' After falling back, your units can either shoot or charge (but not both). 

*'''The Ethersea:''' You get to place up to two Etheric Vortex terrain pieces. Currently, the only existing Etheric Vortex terrain piece is the Gloomtide Shipwreck, which you can either split into two or buy and place two full ships of. The shipwrecks give your units a 6+ Save-after-the-save and have a chance to deal damage to enemies, so they are fairly useful, though less so in a pure Akhelian army.
