The hard part is often that you want sustained damage if you actually want to kill tanks, which means phantom dancer is one of the best items.
This is my line of thinking as well. If Jayce's orthodox shock blast/poke centric builds aren't working in this meta, switch it up.
Looking at Jayce's abilities, I see some interesting stuff:
- Thundering blow is a 20% max health magic damage nuke on a 10s cooldown
- Hypercharge essentially acts as an attack speed steroid on a short cooldown with enough CDR and the damage modifier from it does crit.
- Lightning field deals some really respectable damage if he can live long enough to use it a few times
- Jayce has really solid kite potential not only for himself between Thundering Blow and Transform, but for his team as a whole using Acceleration Gate. Saving it for use as a disengage and later as a chase tool, it becomes a poor man's Sivir ult. There's real value in that.
I'm thinking a CDR heavy build to maximize use of Thundering Blow for anti-tank and peel, increased uptime of Hypercharge (which will act as an attack speed boost, freeing up the need for attack speed so we can concentrate on the other physical DPS stats, AD, crit, and armor pen/reduction).
Frozen Mallet (HP and peel)
Black Cleaver (HP, AD, CDR, Armor Reduction, synergy with Transform's armor reduction, improved kill power for the ADC)
Infinity Edge (AD and solid crit, principal dps item)
Pair that with choice boots. You'll be above 3200 hp, so defensive items should focus on armor or MR if possible, and CDR in those slots would be welcome. Additional offensive items could include Ghostblade (CDR, crit chance, attack speed, kite, armor pen) and Trinity Force but at this point the build is getting very costly. In a pinch you can dump IE and start tanking up after FM and BC.
