Gambit vs Blob
Keep in mind that the Energy score is how may points you can shift around in an action - but they have to come from a source, normally the Action you are using and a related Ability score. Equipment gives free points to an action, and normally don't need energy to be spent on them.
Round 1:
Gambit has 9 points of energy, Charge Object action at 6, Agility 3 and a Kevlar vest (+1) and some throwing spikes (+2). He puts 7 points into Charge Object (6 from his Charge Object score itself, and 1 from Agility). His throwing spikes add +2 free points to that, for 9 total. He puts his 2 remaining points of Agility into Defense, getting 3 points of Defense (with his vest), and leaving him with no more energy.
Blob has 18 points of energy, and drops 12 into close combat (1 from his close combat action, 8 from his Strength (of
ability and 3 from his Durability (out of 6)). He already has 4 points of defense from Toughness, so doesn't put any points in his defense, leaving him 6 points of energy.
Results: Gambit has higher Agility, so goes first. His 9 points in Charged Object (vs 4 defense) hit for 5 x2 damage (10 in all, out of 18 total for Blob). Since Gambit use Agility for his defense, he is able to move away from Blob, who has a speed and agility of 1 each, so the Blob only hits air.
Round 2:
Gambit: Gains 3 energy, for 3 total. Puts 1 energy into Agility and shifts it to defense, leaving him 2 energy.
Blob: Down to 8 health, Blob gains only 2 energy (1/3 health, rounded down), giving him 8 total. Uses 2 energy on Strength to throw a chair, leaving 6 energy.
Result: Gambit ducks behind a dumpster for cover, giving him a +2 situational bonus to his defense (4 total now). Blob throws a chair (3 total, 2 energy from strength with +1 from the chair), this hits the dumpster, but not Gambit.
Round 3:
Gambit: Regains 3 energy, for 5 total. Drops all 5 into Charge Object, with a throwing spike for a total of 7 attack. He gets 1 defense from his vest and has 0 energy left.
Blob: Regains 2 energy, for 8 stones. Puts 6 into Strength to throw a chair again (7 total), and puts 1 stone into Close Combat for Defense (so 5 defense). He has 1 energy left.
Result: Gambit goes first, hits for 7-5=2, x2 = 4 points of damage, knocking Blob out.
