The heroic green steel crafter doesn't work well. Let's say I want to make a kukri with three different stacking kinds of healing amplification and a raise dead clicky, I pick the weapon, I scroll down the first list until I find healing amp, scroll down the second list until I find healing amp, and then the whole screen goes grey and I can't see anything. Had another grey screen event picking some options at random, not sure what combinations I picked for the second one.
Now let's say I want a cloak that's a displacement clicky and gives stacking +6 bonus to charisma skills like UMD and +4 to intelligence skills like DD. Pick the cloak, select Displacement as my bonus spell, and I filter the long list of options to see the ones that give those skill bonuses, but there's still 12 options that give +4 int skills and 8 options that give +6 cha skills divided between "basic upgrades" and "focused upgrades" at the Altar of Devastation. If I ignore the focused ones because I don't need any guard effects and randomly pick the positive option out of the two basic ones, then look at adding the +4 int skills and click the radiance option for int skills, it changes my clicky to something different, so I either need to know ahead of time which one I needed to pick or click through and try them all until I find the right one, IF I even notice it changes my clicky at all. If I go back to the +6 cha skills and instead select the option with concord opposition under focused upgrades, my clicky disappears and gets completely locked out AND the reset button for the +6 cha skills doesn't work anymore, so I can't even clear that off. This appears to happen with any option with a long enough name that the reset button moves under where the ingredients lists are, even if those ingredients lists aren't yet long enough to actually cover the reset and filter buttons. If you leave everything blank except pick "Greater Elemental Spell Power, Wisdom Skills, - Exceptional Bonus +6, Steam Guard" for T3-F, which is only long enough for most of the reset button to be under the ingredients lists, only the left most portion of the reset button can be clicked on.
When I made some green steel items years ago, there was a particular planner that's just gone now but worked so smoothly. It would just list all of the different possible effects an item could wind up having as clickable hyperlinks on one page, with no mention of these different aspects or affinities used in the crafting process. Whenever you click on one, it would select that one as a property for your item and immediately grey out every option that was no longer possible. Click another one, a bunch more would grey out. Click one you already clicked on, it would un-select that one and bunch of options would no longer be grey. You could very quickly just focus on getting the effects you wanted and learn what effects can't be combined with each other on a single item. Would be nice to see something like that again, as I do intend to make at least one more green steel item.
