| Q: | Is a unit that is picked to be the target of an Akhelian Allopex’s ‘Ensnared’ ability ensnared for the purposes of the Abyssal Tendril’s ‘Watery Clutch’ and ‘Crushing Coil’ abilities? |
| A: | No. |
Idoneth Deepkin armies can use the following abilities:
Designer’s Note: Once per battle round, you can use a TIDAL ability from either the Tides of the Sea or the Tides of the Storm. If you do so, you unlock the next ability ln the same column m the next battle round. You can switch columns at anytime, though this resets your progress. For example, if you use the ’Concealing Tide’ ability in the first battle round, in the second, you can either use ’Swift Tide’ or switch columns and use ’Unpredictable Tide’.

Here, you will find additional rules to use with an Idoneth Deepkin army while playing through a Path to Glory campaign. The Path to Glory content in this book is divided into two parts: the Anvil of Apotheosis and Paths for Idoneth Deepkin units.
| Your Hero's Warscroll You can download a blank warscroll from warhammer-community.com on which to record all of your hero’s details. | ||
| The Anvil of Apotheosis is a hero creator. Using the rules in this section, you can create a custom warscroll for a HERO to use in your Path to Glory campaign. This can represent any miniature of your choosing, including one you have lovingly kitbashed or converted. After the Anvil of Apotheosis, you will find 2 Paths for Idoneth Deepkin units. These follow the rules outlined for Paths in the Path to Glory battlepack you are using (e.g. Path to Glory: Ascension in the Core Book). | ||

PARAGON OF BATTLE: This hero has honed their martial prowess across countless battles.
RIDE THE MAELSTROM: At the bidding of this legendary hero, an ethersea vortex is conjured around them and transports them across the battlefield in the blink of an eye. | ||||||||||||||||||||||||||||||||||
Path of The Enclave(non-HERO IDONETH DEEPKIN unit only)ASPIRING: When a unit on this Path gains this rank, pick 1 of the following abilities for them:
REAPING STRIKES: These warriors are veteran soul-raiders who have mastered the swift, clean kill.
SWIFT SEA-RAIDERS: Few can outmatch the pace of the Idoneth.

THE FIRST WAVE: These elite warriors have earned their name by striking at the very forefront of the Idoneth Phalanxes.
FURY OF THE SEA: Akin to the surging sea, these warriors race towards the enemy.
FURY OF THE STORM: Channelling the ocean's rage, these warriors strike with shattering force.
THE CRASHING WAVE: These warriors smash into their foes like a violent flood, giving them no time to react.

| Critical hits have no effect on their own but often trigger additional effects (see 20.0 Weapon Abilities). | ||

| There may be situations when a unit that has STRIKE-FIRST is not in combat at the start of the phase, but because of moves such as pile-in moves, it is ‘pulled into combat’ later in the phase. In such cases, STRIKE-FIRST has no effect on that unit because it was not in combat at the start of the phase. Abilities that allow a unit to use a FIGHT ability immediately after another unit do not override the STRIKE-FIRST or STRIKE-LAST constraints, so you could not pick a unit with STRIKE-LAST to fight immediately after a unit with STRIKE-FIRST. | ||
