pierce memefiltrator Infiltrator, Level 100 (GD 1.1.9.5) - Grim Dawn Build Calculator
obviously just a worse/less optimal version of the messenger repeater pierce abomination from grey-maybe, but the idea wasn’t optimized dmg, but to have fun with pierce box, rune piano and devos
even with silly devos and box; build obviously “spikes” a lot higher in dmg if using chillspikes instead of seal of blades and ditching the runes (also less piano), i just don’t like the feel of the playstyle (or mana drain) 
and “as is” it still did casual content decently (SR65-66 + Mogdrogen, Lokarr and Morgoneth all cleared)
