Many ways, but the easiest is that one can use a roll to create a die-rated character, scene, or object condition, which then can be tagged in later rolls.
Keep in mind, it's always roll many, keep 2, and the biggest unkept is the effect level. Effect level
You get 1 power per power set with that power's die (Most have 1 set, some have 2, a few have 3)
1 die for affiliation conditions
1 Distinction - d4 as hindrance, d8 as boon.
1 die for a suitable specialty
1 d6 for a relevant tool
1 condition - from opponent injury or other condition
1 scene trait.
To create a scene trait, either you drop a plot point and take it as a d6, or you make a roll, using relevant powers, and have to beat the doom pool, which is also keep 2, or you buy an opponent's 1's as complications.
If you do, the largest die (most sides) that wasn't one of the two counted is used as the condition's strength. (Injuries are a subtype of conditions, and conditions of traits - traits are anything with a die code...)
Situation from a game I ran back in 2017.
So, Spidey is scouting ahead in a building, he hears guards. He is willing to risk a turn to make a hidey hole on the shaded part of the ceiling, so his red and blue isn't a giveaway...
Affilitation: Others are in a different scene but the same action sequence, but I let him have the solo d8
Distinction: Wisecracker - as a d4 - and a plot point.
Spider Powers set: Enhanced Senses to know he's got to get in there: d8
Web Slinging set: Enhanced durability seems closest... d8
Covert Expert d8
So, 4d8 and 1d4 total. He drops a plot point for d6 shadow as a scene trait
I don't remember the exact rolls, but that he got a complication was relevant so, we'll fake it.
D8's 8, 7, 2, 1; d6 3; d4 2
Doom pool was 6d6 at that point. I rolled a pair of 6's, no 1's, and don't recall the rest.
the d8 on a 1 is discarded, and the player is offered a condition - d4 "Gotta Pee". He takes it and the plot point.
So, to pass, he has to keep the 8 and 7 on d8's. that leaves a d8 on 2... it has more sides than the remaining d6 and d4.
So his nest is d8.
When he hides in it next round, he gets
Solo D8
Wisecracker d4 and Plot Point.
Spider Set: Wall Crawler d6
Web Set: enhanced durability d8
Covert Expert d8
Webbed Nest d8 - he is skipping the d6 scene condition shadows, as it's only a d6, and you can't tag two scene conditions at once without spending a Plot Point for the second.
The guards, being basic grunts, barely get three dice to spot him, and all at d6's. They also get a free tag of one of spidey's conditions... since he's uninjured and carrying none but the Gotta Pee... that's the one they tag - at a d4. So I'm rolling 6d6 & 1d4. I need the doom pool gains...
but i didn't need 4 1's... they opt for a big one: Power Out d10... That's turning the doom pool into 3d8+1d10... but the guards are now fairly worthless...
Next round, spidey will wall crawl back to the group, with a swingline safety, covert expert, solo, and the new d10 power out and its implied darkness... the round after that, he aimed for a shrubbery.
