Hey, wdym by
- Spend 2 stress to improve your roll
- Spend 1 stress to assist a teammate
There is no push 2 stress for better roll and assist also says "be in position to assist" which doesn't lock it on 1 stress and kinda flexible in deep cuts.
There is also mistake in Devil's Bargain. It is not only reduced to "+1 die, improved position, or greater effect". Deep Cuts says "the GM can offer a player a bargain to achieve a goal by proposing a cost to pay or by introducing a threat." which looks like auto-success for some goal to me.
