Templar - Need some (not much) advice on my build! - Forum

Greetings Exiles,

my Templar in Warbands struggles to deal with maps and i want to hear some advice from youon how to improve him for late game.

The basic idea of the build is to crit the enemies with fire damage, which shocks because of the Three Dragons Mask. It will also ignite enemies because of the Flammability Curse. Also in the final version I will deal extra damage while leeching life.

The main problems are dealing with really big mob packs (especially with summoners in them). Boss fights because i got to get so close. Getting one shotted by random shit.
Current life: 3.3k; Current tooltip dps: 3k with Herald of Ash; Armour 5k; Resistances all without Chaos capped.

Can you give me advice on how to improve my gear (I have like 20c right now + some low currency) and how to (re-)spec my passive tree?

Skills are:

Molten Strike - Weapon Elemental Damage - Life Leech - Fire Penetration
Enduring Cry - Increased Duration - Increased AoE
Leap Slam -Fortify
Flammability
Herald of Ash

Leveling Skills:
Ice Golem
Searing Bond

The skill tree now and how it should be:
