According to my, on the other hand, short experience with Construction, there are two facts that drop this skill from very good to useless. First and foremost, almost every monster 1-hits the altar (I'm currently playing normal orient). Together with its outstanding aggro abilities

and its small area of effect, turns out a very short lived column.
Secondly, there is the Amphetamine thing, which is the main reason I got this skill for. How does it activate? As it did nothing when I tested it on safe places, I thought the whole buff process happened only when injured, so that the Sick bay could heal you and then trigger the buffing. I let some mobs hurt me a bit and then I hit the sick bay button. Worked.
But then I read here that it works "when enemy is in sight". I confirmed it using the skill near some mobs who were busy with the guards (being I full-health), but I can get only Emergency dressing to work.
Does Amphetamine activate upon taking damage? If it doesn't, then it must be "when injured" or something like that. I did got Amphetamine in the beginning and I am now confirming it. When mobbed, you somehow get it.
In any case, I think it takes way too long to get all the buffs. I know I don't know anything about the balance in the mod, but perhaps it would be a good idea either making it indestructible or making the buffs instantaneous. A larger area of effect would be welcomed too.
As always, these are only suggestions and thanks again for the mod.
