Eidolon: standard praetor stats, except he's equipped with a modified sonic shrieker and with has Emperor's Children legion rules, meaning he gets 2+ initiative in a challenge on the first round and he reduces enemy weapon skill by -1. This might seem stupid as he has a master crafted thunder hammer which would reduce him to initiative 1, but on the turn he charges he ignores the unwieldy rule on his thunder hammer making him a whoopingly high initiative (I7). With his thunder hammer with x2 strength he can potentially instant death any t4 character. But keep him away from any t5 character or character with eternal warrior as he can't ID them and they will get 2 sets of attacks before he attacks back, and without EW he is likely to get killed by any Paragon blade or Powerfist equipped model before he gets to attack back.
As his personal little wargear item Eidolon has a modified sonic shrieker which allows him to make a once per game template attack with str2 ap- rending and pinning. Eidolon can also be equipped with a jump pack which greatly improves his mobility and ability to get off charges, and gives him a hammer of wrath attack. This also stacks well with the angels wrath rite of war, which confers hit and run to jump pack models, allowing him to reuse his anti unwieldy special rule on his thunder hammer, benifit from the +1I legion rule and repeat his hammer of wrath attack, while allowing him to flee unfavourable combats.
His unique warlord trait increase charge distances by +1 for all EC units within 12", meaning that this guy is geared to be up in front leading the charge. This works really well in Angels wrath rite armies.
Over all Eidolon is a CQC character who should only attack models he can instant death with x2 Str (which is most characters) and should be leading the force. He is especially suited to jump pack themed armies, but is fully capable of leading a terminator assault unit (+1" charge helps here as well). I like to run him in a squad of jump pack Palentine Blades with phoniex spears in an Angels wrath army or with a large squad of Pheonix Termianators in a Caestus Assault Ram.
That's it for Eidolon, up next Emperor's Children special units.
Thanks for reading and happy Wargaming.
