Build focuses on gun damage, and utility. Build rushes silence wall instead of putting two points into carbine. Because of this, your carbine and grenade will have cooldowns in sync. In lane your biggest damage combo will be to hit them with nade + carbine, and put the wall behind them so when they back away they eat wall damage as well. Wall is the first thing we max to slience durring our full combo. After laning stage everything is situational, but can buy L > R in mid and late categories.
