Answers from posts here in this colour.

1.) What is the base damage of the two?

8 for braziers and 2 for TPs

2.) What is the RoF on these, how many shots per second or minute? I read somewhere about 1 shot every 8 seconds, seems a bit low...

Somewhere around 3 seconds per shot.

3.) How much damage will 2, 3, ... braziers do per volley? I read 10 braziers do 25 per volley. (Yes, more is always better due to crit, just asking about the base damag.)

More means more damage, and most importantly, more crits. - Would be good to have some exact numbers here or a formula to calculate it!

4.) How does that work for TPs? Will more TPs also always do (a slight bit) more damage? (They don't crit, so damage potential is very limited I assume.)

More means more damage, and most importantly, more crits. - Would be good to have some exact numbers here or a formula to calculate it!

5.) How high is the % crit damage if a braziers/TP crits? (It is calculated off the remaining, not maximum BB, right?)

about 30% remaining BB and exactly 15% of the remaining blood

6.) TPs have high range, can't be put out with water like braziers,

They only have 300 shots max (10 shots per 1 tinder, 30 tinder max), so you can theoretically drain it off its ammo in just 15 minutes, also,

[edit:] As I am at it, and it fits in here quite well I guess, one more kinda related question:

7.) How high is the drain due to trespassing (=standing on a foreign pclaim)?

~1 per second.
