Final answer:
The Tiki Armor provides a set bonus that boosts Lightning Aura weapons, as this armor set is designed for summoners, and Lightning Aura weapons are categorized as summoning items.
Explanation:
The post-Plantera armor that has a set bonus specifically boosting Lightning Aura weapons is the Tiki Armor. The Tiki Armor is a summoner-specific set that increases the damage and effectiveness of summoning weapons, which includes the Lightning Aura sentry summons from the Dungeon Defenders 2 crossover event. When you wear the full Tiki Armor set, the set bonus grants increased minion damage which indirectly benefits Lightning Aura weapons, as they are considered part of the summoner's arsenal.
