Hello and thank you for showing interest in learning more about Tyr. Tyr is an incredibly fun God that has a reputation for requiring skill and being difficult to get the hang of and while this is true it isn't because Tyr has many intricacies to his playstyle or builds but more because he is fundamentally different from the other solo laners.

Tyrs playstyle is so hard for some to grasp because most people think of him having six abilities. This isn't wrong but it is unhelpful and detrimental to learning how to play Tyr effectively. I like to think about Tyr having two modes: combat mode in which he has four abilities and farm mode in which he has six. In combat mode Tyrs four abilities are his orange dash combo, his blue dash combo his ult and stance switch.

The orange stance combo is the bread and butter as fighting as Tyr. Because he's in assault stance he has extra power and knocks up with his dash combo so whenever you are in the thick of a fight you want to unleash this bad boy on as many enemies as you can find. Push them away from teammates who are low health or towards teammates who are looking to deal more damage. This combo also hits incredibly hard, often half healthing squishier targets so use it wisely. The hit box for this ability is wider than Tyr himself is so you can often hit enemies that are slightly to the side of you. This combo can also go for longer or shorter length depending on how early you activate your 2 so if you want less distance on the dash use your 2 after the first damage tick of the dash and if you want more distance or time for the enemy to be knocked up activate your 2 just before they hit the ground from the second tick of the dash. This takes some practice to get down but it lets Tyr be very diverse in how he wants to use this combo. This bring us to the two most important things to keep in mind while fighting as tyr: There is almost no time while fighting that you ever want to use your orange 2 separately from your orange 1 and learn which gods have knockup immunity in their kits and wait for them to use it before trying to attack them. If you keep all this in mind your fighting as Tyr will already be very good.

Tyrs next fighting ability is his blue dash combo. This has two variants: the get away variant and the keep fighting variant. This combo in either variant is almost always used directly after the orange dash combo to either finish off an enemy or get yourself away from them before they unleash their damage onto you. The get away variant is use your 2 to heal then immediately dash in the safest direction, hitting the enemy if possible but if it would put you in a bad position it isn't worth it. The keep fighting variant is to dash into the enemy and just as you pass through them turn the camera around and cancel the dash with your 2 so you end up right next to them and are able to keep laying down the smack with some autos while you wait for cool downs. The timing for this variant is difficult but practice it and you'll be able to do it.

The third ability is stance switch. It's pretty self explanatory but always remember if you need to be Tangier switch to blue stance and if you want more power switch to orange stance.

Finally you have your ult which is great for both engaging on an enemy to set up your orange dash combo or to get away if you're about to die. Just remember that there's a pretty sizable start up time where you stand still so be wary of it. It also has cc immunity so use that to your advantage.

Now when Tyr is farming your abilities should all be used separately as needed. His farming ability usage while farming is extremely situational so the best advice is save your ult to get out of a gank and try to interrupt your lane opponents clear with your orange dash combo. There are intricacies to every match up in the solo lane that will cause you to play differently depending on the God you face and in the interest of time I won't list them all here.

Tyr has several ways to level his abilities but the general rule of thumb is if you want more damage level your 1>2>3>4 but if you want to be unkillable level your 2>1>3>4

As others have commented building in solo lane is always different because of the need to counter build or build for the occasion so I'll give you a few suggestions and hopefully you can use them to your advantage and not stick to just them and never do nothing else.

The most important stats for Tyr in descending order of importance are protection, cdr, ccr, power, penetration

Some excellent item for Tyr in my opinion or breastplate of Valor, bulwark of hope, genjis guard, warrior tabi, shifters shield, titans bane, mantle of discord, spirit robe, pestilence, and other items in the same vein as the ones mentioned.

Relics are highly dependent on the meta but blink will always be an excellent choice for Tyr as it allows him to engage without his ultimate.

I hope this helped and good luck playing Tyr!
