Aetherquartz Reserve

Each LUMINETH REALM-LORDS unit in your army starts the battle with 1 aetherquartz reserve. Once per phase, you can say that 1 unit will use its aetherquartz reserve to use 1 of the following abilities. However, if you do so, subtract 1 from that unit's Bravery characteristic for the rest of the battle.

You can that a unit will use this ability when picked to be the target of an attack. If you do so, until the end of that phase, add 1 to save rolls for attacks that target that unit until the end of that phase.

You can say that a unit will use this ability when it is picked to shoot or fight. If you do so, add 1 to hit rolls for attacks made by that unit until the end of that phase.

You can say that a unit will use this ability after it has attempted to cast a spell but before any unbinding rolls are made for that spell. If you do so, you can either add 1 to that casting roll or re-roll that casting roll.
