This PoE 3.12 Templar Guardian Dominating Blow & Herald of Purity build is a good choice for league starter. It is a extremely cheap build with TONS of upgradable options for end-game and viable in both hardcore & softcore.

Note:

Multistrike is meant to be replaced by Melee Splash for the sake of smoother clearing.

Raise Spectre should be linked with Blood Magic to have the Carnage Chieftain monkeys from Act 7 Ashen Fields spam their frenzy charges to your army.
When it comes to the Animate Guardian gear & mechanics I would suggest watching the video linked at the top of this thread!

Leveling Tips

This build can with Dominating Blow from lvl 28 reach Blood Aqueducts in about 6h fairly easily. However, I felt it to be faster to simply focus on Herald of Purity & Smite. This can easily be combined with a Holy Relic as well as with a pack of pack of Zombies which comes down to a matter of personal preference.

The idea is to link your Smite this way:

- Smite, Ancestral Call, Melee Physical Damage, Added Fire Damage

And your Herald of Purity like this:

- Herald of Purity, Melee Splash, Melee Physical, Minion Damage

This in combination with a Blind linked to our Holy Relic makes leveling extremely smooth & efficient.

Since the end-game gear for this character is solely focused on high life with capped resistances, so does the leveling! However, it is recommended to use a 1H weapon with proper damage during the lvling sequence till you hit about lvl 70 in which case you can easily switch to Dominating Blow and a Brightbeak. Obviously this can be done earlier if you so wish but without extensive knowledge and/or experience with this type of build I wouldn't recommend switching before that.
