Ah. I wasn't aware of the trade-off ability. But looking thru my Savage RIFTS The Tomorrow Legion Player's Guide (2016), I only see that "2-for-1" tradeoff offered on the MARS F&G table, but not on any of the others...???
In addition, the cyborg build gives "two rolls on any of the following tables: Cybernetics, Close Combat Weapons, Ranged Weapons, and Training. They gain a third roll on any table except those dealing with magic, psionics, or Body Armor." So, 3 rolls, not 6.
Are you using a different RIFTS Setting? And what does "HJ" and "IF" stand for?
Ah, I stand corrected on the Cyborg's count--I'm used to most of the IFs (Iconic Frameworks) having a total of 5. With three rolls, the player would need to put all three on the Training table, and hope for the best. If they get EITHER the "Combat Edge" or the "Martial Artist/Brawler" result with one of those three rolls, then the other two can be traded to get the second one, per the rule ValhallaGH noted.
Actually, for the SuperCheese version (wherein I just pick the roll results I want to, in order to push the concept as far as I can) of the Combat Cyborg, the real way to go is to use the third roll to take Background Edge off of Experience & Wisdom, select Rich, and then use the 2 rolls on the Cybernetics Table to get two levels of Bionic Strength Augmentation. That brings us up to d12 + d6 + 12 at Novice. Oooh, and I flubbed the "SuperCheese" option for the MARS Power Armor Jock, too:
Human MARS Power Armor Jock
Triax Predator (Base Strength: d12 + 6)
d4s in Smarts and Agility; d8s in Vigor and Spirit, d6 in Strength to start
F&G Table: Two HJ Table Results (Both on Experience & Wisdom)
F&G Table: Strong & Powerful (+1 Strength Die)
F&G Table: Two HJ Table Results (Both on Cybernetics)
HJ Training Table: Martial Artist and Brawler (MA gives +d4, Brawler adds +2 to damage)
HJ Training Table: Combat Edge: Improved Martial Artist (gives +d6)
HJ Experience & Wisdom Table: Background Edge: Rich
HJ Experience & Wisdom Table: Background Edge: Filthy Rich
HJ Cybernetics Table (5 rolls from Filthy Rich, 2 from F&G directly): x7 levels of Bionic Strength Augmentation.
x2 Hindrances: Martial Arts Master x2 (+4)
Racial Edge: Martial Arts Master (+2)
Novice 1 and Seasoned 1 Advances: Both Strength-die bumps
MARS Advances: Two-Fisted, Ambidextrous, Trademark Weapon (Unarmed, if your GM allows this), Frenzy
Now he's at d12 + d6 + 15 outside of his suit of armor. In the armor, it's only d12 + d6 + 14, but it's Mega-Damage.
So stay in the Power Armor if you need to punch out a tank, and get out if you want to simply push their nose through the back of their skull.
