Its been discussed many times about the forge rng.
My suggestion to reduce the rng effect, but still to give some amount of difficulty and planning would be to give the boons a ‘slot’ weight as well as a ‘gum’ weight.
On the forge screen, if we imagine the boon slots are numbered 1, 2 and 3 from the bottom.
As an example, let’s take everyone’s favourite special gum on a hammer.
Special gum adds weight to 2 boons, aoe and magnet.
What if slot 1 also added weight to aoe?
So if the gum adds 10 weight to each, slot 1 also adds 10 to aoe.
So aoe would be +20 weight, magnet +10 weight and the rest the same as always.
Slot 2 could add the extra weight to magnet rather than aoe.
If the gum has a 3rd boon it could be slot 3 weighted.
The slot weight would only be added when a gum was in use.
I hope that I am explaining my thoughts well enough to be understood.
Of course, I have not thought of every scenario, and this would just be the basics of the premise.
I’d leave the devs to fully develop it.
It would give the ability to be a little more targeted in approach, have the need to be a little more tactical in planning the forge and still leave a bunch of rng on there, cos apparently that has to be a thing!
