Archon Shards - need 2 emerald corrosive stack shards for full strip from 4

Melee - use viral + electric, ideally with electric outweighting viral eg Dual Ichor Influence: Dual Ichor: https://overframe.gg/build/572811/
You can also use melees like Fists that have a 30x ground finisher multiplier. Sandstorm allows very easy ground finishers that trigger almost automatically while spamming light attack. [Furax Wraith] is a fist that can also utilize electric influence extremely well due to the status chance evolution.
