As in title: Set up a build with 6 blue cores for a max skill tier shield (and low skill tier second skill), get kills with a future perfect weapon. Only the lower tier skill will be bumped up and overcharge will never happen for the tier 6 shield.
for reference, other talents like energize and acosta's go bag work with the same setup.
