For this build, we've chosen the Morning Star weapon. A hammer weapon fits well for this build since charged heavy attacks from a hammer deal 36 stance damage, and block counters also deal 36 stance damage. This is important since most bosses in Elden Ring have about 80 Stance while others have 100+ (120 for example for Godrick the Grafted). And if you deal the said amount of stance damage in a short period, they'll become vulnerable to critical attacks, hitting them a couple of times, or even a combination of both. Combining the Cragblade ash of war for this build will help you achieve the goal of easily breaking a target's stance since this skill applies a buff that increases physical attack power by 15%, stance damage by 10%, and stamina damage against a blocking enemy by 50%.

The ideal strategy when using the weapon and the skill is to activate the buff with Cragblade before you engage a boss battle, use charged heavy attacks as quickly as you can, and use a block counter to break their stance, following up with critical attacks or a string of attacks to punish the target while it is unable to move. Generally, you can use other hammers but the Morning Star is the best weapon to use for this build since it has bleed build-up that applies blood loss which is a good negative status effect to apply on some bosses. This weapon can be found in a chest inside a broken Carriage at the Weeping Peninsula just a bit south of the bridge from Limgrave. [Elden Ring Map here] Video of the location of the item. This build also utilizes the Manor Towershield, it has 67 Guard Boost, which is a good shield that you can pick up early in the game and seemingly is effective when using block-counters.

The Tower Knight build uses the Knight Set which can be purchased from the Twin Maiden Husks at the Roundtable Hold. When it comes to Talismans, this build uses the Green Turtle Talisman for Stamina recovery allowing you to block and attack frequently without worrying too much about managing your stamina, the Axe Talisman which increases the damage of charged attacks since you'll be frequently using charged attacks to get that stance break, the Curved Sword Talisman to increase your block counter damage, and finally, the Greatshield Talisman to reduce stamina damage taken while blocking. Depending on what you need, you can swap out the Greatshield Talisman for others such as the Ritual Sword Talisman if you want a boost to your attack power when your health is at maximum.

Moving over to the Stats, the build runs at 50 Vigor, 25 Mind, 30 Endurance, 80 Strength, 12 Dexterity, and you won't need any Intelligence, Faith, or Arcane for this build. The idea of the Tower Knight build is to have enough health to trade attacks, be aggressive in boss encounters, and increase survivability since the nature of this build will have you taking damage when in combat. Mind can be at least 25 or even lower, you just need enough to use Cragblade, maybe 2 times at max when using the skill, depending on the boss you're fighting. Endurance is up at 30 to gain high stamina to do multiple actions such as blocking, block-counters, use heavy attacks, and to be proficient in wearing the Knight Set. Strength is up at 80 to further increase the damage of your attacks.
