Get Fed Top
Like any hero, you want to get fed. However, if you get full build before the enemy team does, you will wreck them. Krul will drop off somewhat late game so you want to kill the laner as much as possible, then try to push the enemies out of their jungle, take their farm, and leave them hesitant to go back alone. This will directly affect the late game making you more fed and easier to dominate. Try to stay away from "fair fights" until late game and pick them off one or two at a time. It is irritating to get constantly ganked and kill, it takes away from their farm and makes your laner have an advantage. They may even have a person get mad enough to rage quit and be a player down.
Ganking / Ambushes Top
Use his herioc perk during ganks and you will kill enemies a lot more because they have less time to react. Also use it in teamfights to make your way to the enemy carry and burst him down. Start at the bottom set of minions and then work your way to the top one and then go to lane to gank almost every rotation after getting tension bow. Early game the dead mans rush with tension bow can get a lot of laners down to half health or less.
Always focus the carries, mainly the ranged one(if there is one) because they can kite. Try to always get the jump on enemies and fight from ambushes where your team sits in the bushes. Dead mans rush grants a nice health barrier so be sure to use it wisely
Why The Ability Choice? Top
His dead mans rush does amazing burst damage early game and provides a nice health barrier that helps when turret diving and later in team fights. His spectral smite provides him with a nice damage dealer and life sustain. It works well with breaking point late game hence maxing it out second. The ult is fantastic, however, the first two are much better on this build.
Tension bow does massive burst damage early game and should always be the first item. Tier one boots are fine seeing as the heroic perk greatly boost kruls speed. Next, you want to get aftershock because it will further enhance your burst damage and reduce cool down times. Try to get tier two boots after this because your spectral smite with become more viable. Next, get shiversteel and tier three boosts so you can chase and get away. Shiversteel can slow down fleeing targets and help you get more stacks. Next, you want to get a defensive item, aegis preferably, especially if they use multiple cp builds and/or aftershock or possibly an atlas pauldron if they have attack speed items or facing another Krul. Late game, you want to sell tension bow because it drops off and is basically useless. You will want to wait until you can sell tension bow and have enough for breaking point because it becomes a more viable build and thats what you have been building the whole time. Most likely they will not have built an atlas because you did not ever build attack speed early game. After that you will want to build bonesaw so you can melt through armor and have more attack speed to get stacks faster. You will want to get infusions when needed, crystal are better until you get breaking point then weapon infusions will be the way to go. Also, you will want to keep a few halcyon potions to make sure your energy is fine because your abilities keep you alive.
