D&D 4e Modron, review please?

[Alfray Stryke]

I'd like a review on the following alterations to Warforged as a DM is running a Planescape game, so I've attempted to create Modrons;

Ignoring any fluff

Height 6ft, Weight 285 lb
+2 Con, +2 Int
Speed: 5
Vision: Normal
Medium Size
Languages: Common

+2 Endurance, +2 Arcana or +2 History
Following same as Warforged
Living Construct
Unsleeping Watcher
Warforged Mind
Warforged Resilience
Warforged Resolve

I'll change the names and fluff of various abilities later, this was a quick attempt.

Traditionally they had a +1 Str and Int, but Con and Int makes sense too and let's them be good Swordmages (my favorite class) so I'm not complaining (I also don't know of any Str/Int classes).

Looks fine to me.

You could use the PH3 mechanic and have +2 Int and +2 Str or Con.
