Hey I am a native German speaker and thought I could help out in this forum and just give a translation for the leaks we have.
Skipping the point table since it should be self explanatory even in German. Though if questions arise feel free to ask.
Great Nations:
Iliatha
Add 2 to the bravery characteristic of VANARI- and AELEMTIRI-Units from ILIATHA .
After a friendly VANARI-Unit from ILIATHA uses a command ability, you can choose one friendly VANARI-Unit from ILIATHA within 3'' of said unit. If you do so, the chosen unit can also use that command ability without spending a command point. You can only use this ability once per phase.
Command ability: You can use this command ability in your shooting- or combatphase. If you do this, choose 1 friendly VANARI-Unit from ILIATHA with 2 or more models. You can reroll hit-rolls of 1 for that unit.
Artifact of power: The first time the bearer dies roll a dice. On a 1-3 the bearer dies. On a 4-6 the bearer does not die, all wounds allocated to him are healed and all wounds yet to be allocated to him are discarded.
Syar
SYAR-Units start the game with 2 aetherquarts instead of one.
Command ability: You can use this command ability when a friendly SYAR-Unit could use an aetherquarts ability, even if a friendly SYAR-Unit already used one in that phase. If you do so, choose one friendly SYAR-Unit with at least 1 remaining aetherquarts and is completely within 18'' of a friendly SYAR-HERO. The unit can spend 1 aetherquarts to use the aetherquarts ability.
Command trait: At the beginning of the combatphase you can choose 1 enemy HERO within 6'' if the bearer. The chosen enemy HERO can only choose this general as a target in this phase. In adition you can add 1 to attacks targeting the chosen enemy HERO. (Here i would like to add that is does not specifically state that its only your generals attacks. So putting your general behind or into your pikemen would mean that those also get the +1. It would be synergistic with all heroes of us being noncombat oriented at least for the non named ones but it could also be sloppy writing on GWs part.)
Artifact of power: Choose 1 melee weapon of the bearer. An unmodified hitroll of 3+ always hits. An unmodified woundroll of 3+ always wounds. An unmodified saferoll of 3 or less for wounds from this weapon are always failed.
Ymetrica
The trait "Hard as Stone" changes the rend characteristic of attacks targeting ALARITH-Unit from YMETRICA to "-" if the attacks targeting the unit have a rend characteristic of -1 or -2.
Command Ability: You can use this command ability at the end of the combatphase. If you do so choose 1 friendly friendly ALARITH-Unit from YMETRICA that has just for the first time this phase forced an enemy unit to move with the "Tectonic Force" ability and that is completely within 18'' of a friendly ALARITH-Hero from YMETRICA. You can use the ability "Tectonic Force" again by choosing another enemy unit within 1'' of the chosen friendly unit.
Command Trait: When this general fights instead of piling in and attacking you can choose him to make a single powerful blow. If you do so choose an enemy within 1'' and roll a dice, on a 2+ you deal d3 mortal wounds.
Artifact of Power: Choose 1 of the bearers melee weapons. Once per phase you can add 1 to the damage inflicted by 1 of the weapons attacks. Aditionally whenever the bearer suffers a wound or mortal wound roll a dice. On a 6+ negate it. Aditionally whenever the bearer is affected by a spell or endless spell you can roll a dice. On a 5+ ignore the effects for the bearer.
Zaitrec
Add 1 to the first cast-, dispell- and unbindrolls of each friendly ZAITREC-WIZARD in each herophase. In addition each ZAITREC-WIZARD-HERO knows 1 additional spell from his lore of magic.
Command Trait: This General can try to unbind an additional spell in each of your enemies herophases. If he tries to unbind his second spell in the same herophase you may reroll it.
Artifact of Power: Roll a dice whenever assiging a wound or motal wound to the bearer. If Teclis is part of your army and on the battlefield add 2 to the roll. On a 6+ it is negated.
Lore of Zaitrec: Each ZAITREC-WIZARD knows this spell in addition to any other spells. This spell has a casting value of 7. If succesfully cast choose 1 enemy unit wholly within 24'' and visible to the caster. Half the movement characteristic of the chosen unit until your next herophase. The roll a dice. When the roll equals or exceeds the savecharacteristic of the chosen unit suffers d3 mortal wounds.
This has taken some time and i dont want to spam this forum. If you would like me to translate the warscrolls and spells for you i would do that tomorrow. If this is too much spam and not needed i apologise.
