Boost/Hinder
You can use the Boost action to help yourself or
an ally, or use the Hinder action to weaken an
opponent. When you use a Boost or Hinder action,
you make a mod — a bonus or a penalty to
someone or something’s actions. The Boost action
creates a positive mod, called a bonus; the Hinder
action creates a negative mod, called a penalty.
Mods can do a lot, from having the right gadget at
the right time, to knocking an opponent off-balance,
to grabbing the edge of the blast door and pushing
with all your might, or even delivering a rousing
speech, inspiring your allies.
Use the effect die to determine the size of the
mod you create:
EFFECT DIE
RESULT
MOD SIZE
0 or Less No bonus or penalty is created
1-3 +/- 1
4-7 +/- 2
8-11 +/- 3
12+ +/- 4
26

example on page 31!
Actions
Whenever you create a mod, give it a name, with
either a quick description or a comic book dialogue
quip. Such as “Pocket Analyzer +2” or “Watch out
for that first step -3.” To keep track of the mod,
write its name and value on a notecard in front of
whoever that mod is affecting now.
A mod applies to the effect die rolled on a later
die roll, either adding to or subtracting from the
result. You, as creator of the mod, decide who uses
that bonus or penalty as long as it makes sense in
the fiction of the scene — not everyone can just
grab the “Massive Sword +4” you found and use it.
Similarly, if a villain or lieutenant or minion creates
a mod, the GM decides who that mod applies to
and how that mod takes effect.
Usually, mods go away after one use, though
abilities and effects may extend their duration. If
you want a mod to last for two uses, you can take
a minor twist that relates to the situation when you
create it. Some abilities create exclusive and/or
persistent mods. You can only use one exclusive
bonus and one exclusive penalty per roll. You may
use other mods alongside exclusive mods, but only
one of each exclusive mod. Persistent mods last
until an effect gets rid of them, until it makes sense
for them to stop (someone makes an Overcome
action to stop it, for example), or until the end of
the scene at the longest.
