Parker has this trigger:
"Empty The Chamber: Before flipping damage, discard any number of Upgrades from this model to deal +1 damage for each Upgrade discarded."
And also has this ability:
"Limited Supplies: Once per Turn, after this model discards an Upgrade, add one Soulstone to this Crew's Soulstone Pool."
So, should they work together?
Also most of his upgrades have this part about discarding them:
"This model gains the following Ability: Fast Getaway: At the start or end of this model's Activation, it may discard this Upgrade to take a Walk Action."
Should two abilities work together?
