All excellent tools, I used them all and wouldn't play the game without them! One I would add is bring a cheat sheet, preferably that you've done yourself. It'll help make sure abilities are done in the right (sub)phase and make the game cleaner overall.
on the same idea as stathammer is Anydice. It's a bit more complicated/ harder to get into, but allows you to see the distribution (helpfull on swingy stuff like doomwheels), but helps, as average is not the most important on every distribution. helped me getting a feeling for deciding things like "do i overload the doomwheel?/bombardier" Edit: so you can see: hey if i overcharge i have a 80% chance of this outcome, in which case im that likely to explode which would lose me that much dmg with that chance in combat (also perfectly combineable with stathammer i guess. It's a bit of coding though.
got a feeling this channel is gonna get pretty big, its basically exactly what looked for when i started in 1.0 some critiques: hes got a great narrators voice no doubt but needs camera training - he feels nervous when he shouldnt be. the mans got great content and high quality vids
