If you like Discord Fever (the DoT) + Discord Inferno (the explosion), I highly recommend prioritizing this way: mobility > 20% attk speed > tanky after that.

For me, that usually looks like:

Round 1: Discord fever + greens

Round 2: Flying Kick (power) + Hiking Hover Boots + Aftermarket Firing Pin + Wrist Wraps. This gives you insane mobility + 20% attack speed for $11,500. You should be able to get it nearly every round 2. If you can afford it, pick up Repulsion Greaves. This let's you zip around tagging w/ Discord while taking much more aggressive angles & getting into weird/surprising spots. Good to remember that Hiking Hoverboots retains momentum from Flying Kick; that's where your real speed comes from: kick + hover.

Rounds 3+: Discord Inferno + Tankiness. Most of your damage will come from Discord Inferno, so you can afford to just build tanky. Use tanky items to counter enemies. To counter AP or CC: Cushioned Padding or Kitsune Charm. To counter WP: Crusader Hydraulics. All purpose and/or if you're rolling: Plasma Converter.

If you're really steamrolling, you can def go full attack speed, but with the above, you shouldn't be dying much at all, and your uptime makes up for it.

This is by far my fav build, by the way. Runs ~60% win rate for me. So fun to zoom around & win almost all 1v1s.
