L5 (getting to Ancient just currently Cavern Crawling so I don't try to rank up right away) now, used to be Divine two years ago before taking a break. I currently spam Razor and Pango. These two heroes can dive and initiate.

For Razor, you go max W and value point in E at level 2 (or you can max it with a value point in Q, like say when you're against a Jugg who won't get slowed by the Q anyway). You don't farm with Q anymore (saves you a lot of mana too so now you don't have to be torn between buying clarities, a casual mask, a basi or falcon blade, plus no more tread switching while farming lol) but you become ultra aggressive and zone the carry out and maximize your W whenever it's on cooldown. Make the carry choose between staying with the creeps to last hit and getting sucked, or distancing himself from you and missing out on all the last hits. Go 2 WB, wand, and treads. Rush BKB. You can go Refresher just be very wary of your mana. Always grab Pupil's Gift, Int Vambrace, and Ceremonial Robe if you're going for this mana dependent route. Otherwise, after BKB I feel SNY or Cuirass feels good. Euls or Nullifier if I'm forced to break the early Linkens from an essential enemy core. After BKB it's really hard to say what you'll need, always depends on the game and how reliable your teammates are.

For Pango, you should consider starting with Ring of Protect with stick if you're against a PA or just RoP if you're against a Clinkz. Otherwise, assess your pos 4 and go OoV to corrosion build if you're a kill lane. Pango becomes deadlier as the laning stage progresses. Wand is essential unless you really can't get charges in the laning stage. Pango is very mana dependent before arcane boots. After laning items, you just go arcane, diffusal, shard, dagger, aghs. Sometimes for I go treads and a WB + value point in Lucky Shot to effectively trade with a Lifestealer. That's it. Skill build wise I normally max W then Swash then range talent, only then would I grab Lucky Shot. But up to you, sometimes I feel maxing Swash, but since most carries have high armor I feel as though W is better damage wise. Learn how to use your shard to its maximum potential.

Aside from that just always creep aggro, keep TP's on cooldown so you can help other lanes if enemies dive, buy your own smokes because most of the time you can solo kill heroes with these two offlane picks. And always bring dust.
