Did some lab work in the tavern with a squire. What I've found is that physical damage upgrades to 1.15 of previous damage. Elemental upgrades to 1.20 of previous damage. Physical upgrades seem to cap off at 80 per upgrade whereas elemental damage seems to be capped at 300ish.
As a general way of estimating weapon damage for upgrades:
- For physical damage, every 5 upgrades doubles the amount
- For elemental damage, every 4 upgrades doubles the amount
A 50 base physical weapon with 20 upgrades will end up at roughly a final stat of 800 (818 to be exact).
Damage per hit depends on your class and the attack stat of your character.
For the squire, the 2nd strike in the combo is at 1.20 of the base damage, 3rd and 4th are at 1.40.
I'm currently unsure of how hero strength factors into this. I originally thought it was .03 phys damage added back per point, but that is mistaken. My weapon of 432 on a squire with 46 str does 848 dmg which is 1.962 repeat damage, divided by my str thats a modifier of 0.042 added per Str point, but my squire with str 74 and sword 58 dmg is doing 129 so 2.224 damage, which when divided by str is 0.03 per point.
I'm assuming that each str point has less of an impact on a curve but the formula I don't know.
Here is my observations from playing with darkness trap for a few rounds:
All enemies within the darkness trap cannot attack with the following exceptions:
- Ogres can still attack through it
- bosses ignore it as well
- Assassins can jump out of it and attack you
- It WILL prevent kobolds from detonating for a short while even after they have lit their fuse. But if you attack them they'll still explode.
If it happens that you upgrade a trap so it eventually covers the edge of a crystal, enemies will not attack the crystal either because of #1.
Enemies will just bunch up near the traps and die >:). The enemies don't seem to try to move and find another path, they'll just cluster there and take constant damage until they die. Ranged units outside of the path will still attack.
And lastly, it affects any enemies within the cloud. If you are standing within it, things outside can still shoot at you and see you.

You are correct that it doesn't scale very well. Having ~600 range will give you more than enough range, especially if they are under Buff Beams.
600 range will let you hit the upper floor dummy from just about anywhere in the tavern.
