Poisonburst Arrow through Act 4 · Brutus' Lead Sprinkler + Archon from there on — from Goratha to DreamcoreChayula's Dream

One arrow poisons the pack and the heralds chain-explode everything — fast and cheap through the mid-campaign. At level 45 Strength takes over: two Brutus' Lead Sprinkler replace the bow, and everything you've invested keeps paying off until level 80, when the Archon's tornadoes start firing on their own. Tell it your level and what you have.
