How it shakes out

Reference builds: level 50, BIS (the first in each slot on the PvP tab of the Items) with the Gun Store and Chop Shop business functions at level 5, Mansion in a tier 3 district, no drugs and no megastructure. “1v1 duel” is the chance of you dropping the other guy before you go down (10,000 simulated games, always the same draw), one Corner game until the knockout, taking turns acting, no tools, no skills and no drugs, with the standard weapon sequence (My Little Friend, AK-47, then fists), crits on every hit and counter, bursts in two rolls and whole-number damage (Build 16). “Weapon” is My Little Friend, the duel's first weapon, with both burst shots landing. The weapon hit already factors the average crit.

The opponent you build

Build the other side the same way: stats, house, megastructure, drugs and gear. He goes in the last row of the table above.

Opponent's build

Opponent's gear

Megastructure: one building per player, from level 40. Its stats count as gear (HP included).

Business functions: the Gun Store gives STR and PvP Power, and the Chop Shop gives SPD. They count as gear everywhere, one function per type, from your highest-level business of that type. The wiki only lists levels 1 and 5.
