When farming, time the activation of your Acid Hunters so that you fire it in between your autoattacks. That way, you farm as efficiently as possible and you can also push the lane very fast this way. If no enemies are nearby, begin farming a creep wave by hitting the back line of enemy minions with Noxian Corrosive Charge and let the corrosion deal it's full damage to the minions while you destroy the close-attacking minions with your autoattacks and Acid Hunters.
Acid Hunter can hit through walls, giving an unexpected attack with a surprising amount of damage.
Acid Hunter has good range and hits unarmored targets hard even when not locked-on. Getting in the habit of using the skill shot occasionally, even when Noxian Corrosive Charge isn't necessary applied, helps to throw enemies off their rhythm and makes you a threat even when your lock-on fails or wears off.
You will only slow enemies as long as your shield remains active, so consider putting ranks into Terror Capacitor to provide Urgot with a crippling slow, better chances of maintaining it and greater durability in skirmishes.
Remember that although Hyper-Kinetic Position Reverser grants damage reduction, you are not invincible. Take note of nearby towers or enemy champions that can burst you down before its channel is complete.
Hyper-Kinetic Position Reverser suppresses the target while channeling, so it can be used for deterring an enemy's escape for your team to finish off your target. It can also be used to interrupt your enemies' channeled spells, such as Katarina's Death Lotus.
Urgot's skillset makes him most effective in eliminating the enemy team's carries, but don't overestimate his toughness. In general, it is a good idea to keep your distance from DPS champions until they have been weakened or separated.
Urgot'sHyper-Kinetic Position Reverser can be used over walls to pull an enemy through it, provided that he can see the enemy. This can be used offensively and defensively either when you are being chased, ganking in the jungle, or caught in a teamfight.
Urgot is great at harassing. Use the long range and reasonably wide area of effect of Noxian Corrosive Charge to weaken enemy champions with impunity while simultaneously farming.
One to take down an enemy champion as Urgot is to conserve your abilities for chasing. As soon as your target begin retreating, pop your shield and keep hitting them with as many autoattacks as you can until Terror Capacitor's time limit is almost up, then catch your victim with Noxian Corrosive Charge and follow up by striking with as many Acid Hunters as you can before your opponent is out of range.
Urgot's passive damage reduction from Zaun-Touched Bolt Augmenter, extra survivability from Terror Capacitor, and the armor reduction from Noxian Corrosive Charge make it extremely difficult for opponents to gauge his strength, frequently causing enemies to trade blows with Urgot and usually take more damage. Don't overestimate your foe's intelligence or you will miss opportunities to take them out when they make this common mistake.
Other standard attack damage items such as Infinity Edge are not as effective since Urgot's main damage source, Acid Hunter, cannot crit and does not apply on-hit effects.
Last Whisper is also a good late-game item if the enemy team is building armor to counter you.
Urgot can be mana-hungry in the laning phase, but buying Tear of the Goddess should eliminate mana problems for the rest of the game. If you decide not to focus your build around picking up Manamune early, other mana regeneration sources are recommended.
Guardian Angel can be an effective defensive item for Urgot as his Terror Capacitor can offer the additional time necessary for a last escape, or give you time for cooldowns to refresh so you can quickly focus down low health enemies who linger nearby.
Another good option may be Randuin's Omen. It's armor and health boost will make you hard enough to kill after switching places, plus it's slowing component may prove useful when escaping or after switching places to slow surrounding enemies and make them easier to be caught off.
Instead of Hextech Gunblade, Death's Dance may be taken. It also provides healing via Acid Hunter, but grants much more useful statistics as cooldown reduction and lots of attack damage. It's damage mitigation component also allows him to survive longer after reversing.
Attack damage items are worth buying for the early game; however, due to the risk of using his ultimate in the late game, it is recommended to build some survivability items afterwards.
Cooldown reduction can let Urgot fire more locked-on Acid Hunters before the Noxian Corrosive Charge debuff fades. With no CDR, he can fire 3 shots per lock on. With 16.7% CDR, he can fire 4. With 37.5% CDR, he can fire 5. However, the above values are mathematical and do not take into account input lag or delay.
Glacial Shroud is an effective mid game item for Urgot as its armor helps him fight physical damage champions, while the mana and cooldown reduction help him spam his Acid Hunter and adds to the damage from Manamune. Frozen Heart is also effective for the same purpose.
Another way, however mostly tanky, is to buy Righteous Glory. It's haste component may help you cast place-switcher, health bonus will make you more hard to kill and it's mana boost combined with Manamune will grant you some more damage.
However, if tank items are good on Urgot, you cannot ignore getting some attack, because enemy team can just ignore you. One or two are enough,three at max if your team does not have a tank/initiator.
An early Hexdrinker is great because in addition to improving Urgot all around, it can later be upgraded into Maw of Malmortius, which adds both attack damage and magic resistance, and as such it can complement Urgot's damage output with improved survivability.
Furor is a strong upgrade for Urgot's boots as his Acid Hunter hits will proc its speed increase. This allows him to kite and chase enemies very well.
Urgot does only physical damage, so getting armor items is effective in mitigating his DPS.
Move erratically to avoid being hit by Noxian Corrosive Charge thus preventing lock-on with Acid Hunter. Experienced players will often wait for you to move into position for an attack or minion kill. Use feints to cause them to misfire.
Champions with gap closing abilities can combat Urgot effectively by staying within close range and timing their dash to coincide with his Noxian Corrosive Charge.
Urgot lacks mobility and is vulnerable to champions with good DPS, especially those with frequent disables or items such as Frozen Mallet.
Avoid committing to a close quarters 1v1 battle with Urgot unless you are certain of an overwhelming victory. His abilities make it difficult to escape a losing battle.
Urgot tends to be rather predictable, in that whenever he lands a Noxian Corrosive Charge, he will almost always chase the target in order to land his full combo. This can be easily exploited to bait him into overextending for a gank.
Keep in mind, however, that after Urgot reaches level 6, Hyper-Kinetic Position Reverser can allow for an easy escape by switching places with the ganking champion. Either make sure the ganking champion has a way to block or break the suppress, or be prepared to interrupt the channel. If he is unable to use his ultimate to escape, Urgot is usually a relatively easy kill.
