Well he is 225 points to start with and so you except much! and so he will also need protection so I wouldn't ever spend extra points on the command barge!
Statline-
Average, nothing stands out here really! Just a normal Necron Over Lord with 2+ save! So already I would so not worth his points! But lets look at his war gear amd special rules!
War Gear-
BloodSwarm nanoscarabs-
Unique ability to Imotekh, it basically helps your flayed ones deep strike near a infantry unit which you have chosen at the beginning of the game, great if you like flayed ones, not so great if you dont, I will let you make up your own mind on this ability, but I think it is pointless.
Gaunlet of fire-
Why the hell has Imotekh got this? yes he will almost always hit and wound with it, but no power weapon? surly a 225 point character shoud ignore armour saves? well he doesn't! So err that is a big put off with me, but lucky he is a good support character! (pricey tho)
Phase Shifter-
No ifs, No buts! LOVE IT! 3+ invulnerable, great no problem here, and yep Imotekh should have it at his points csost!
Phylactery-
meh, average at best wargear, only good if reanimation protocols work!
Sempiternal Weave-
This is what gives him is 2+ armour save, so yep good wargear!
Staff of the destroyer-
Right a one use only shooting attack.. Which I love! 2D6 from Imotekh into any direction and you could have a lot of enemies (and maybe allies aswell)
So wargear is a big meh, some good, some average, still not worth his points cost! BUT Special rules is where the fun is!
Special Rules-
I will not cover Independent character, Phaeron, Reanimation protocols and ever-living as they are standard things
Humiliating defeat-
So if he kills a character, he make sit easier to win combat! Meh its ok, but with no power weapon of a kind, he has to kill someone first!
Hyperlogical Strategy-
Awesome, except against Orks, and useless if you are going first anyway! Just a better seize the initiative roll!
Lord of the Storm-
Right this is where Imotekh becomes the STORMlord, so basically he makes the game night fight(in till you roll a bad number)
and while it is night fight he can try and hurt stuff with d6 str 8 hits on any unit the storm hits (it needs a 6 to hit, but every enemy unit has to roll mwahahaha) so awesome, but unreliable!
Overall-
Not worth his points, no power weapon and only 1 main special rule, maybe is he was 35-45 points cheaper, but he is average at best, there are better special character in the book for less!
Bit disappointed as he is meant to be our "big guy"
O well, next up is Nemesor Zahndrekh (when I get a round to it)
