Engineer constructs

Can some one tell us at what lvl of engineering gets you what skill and what level your character has to be to use each of the skills. For eXample, lvl 0 engineer - small block ect...If theres a topic or post with it some where i certainly couldnt find it uses the searh feature.

It is not yet finalised, but I posted the current situation 5 mins ago in this thread

Each level of Loaded Engineer gets you one more point in each category. The cost in points for various summons will be changing shortly. I am not sure what the final configuration will be - that is down to Druid and Shantara, but it is likely to be something like:
Sentinels: Lightning 3 points, Defense (possibly) 5 points, Sentinel 6 points
Turrets: Minigun 4 points, Energy 8 points, Ball 10 points (No link turret)
Vehicles (in VINV): Scorpion 5 points, Hellbender 8 points, Goliath 12 points
Blocks 1 point

Any update on this?

EDIT:
Including what player level you need to be?
I've noticed I can purchase LE levels that show me artifacts which my player level cannot summon -- e.g., I have a Minigun Turret artifact, but my player level is only 28 and cannot yet use that artifact.
