I believe that my problem with your build is that I don’t see a solid concept.
Basically the only thing that you are using the Soldier mastery for is a little tankyness, yet you have put a considerable amount of skill points in that mastery.
In general you build seems to lack synergies and useful skill combos.
PRM has no attack damage scaling, so it doesn’t matter how much base damage your weapon does, and so you usually don’t get a benefit out of wielding a weapon that would be good for a Soldier.
Additionally most of the active Soldier skills are probably of no use to you, either because you need a shield or two-handed weapon for them or because they don’t fit into the ranged PRM style of play.
So, I would generally suggest:
A) If you want to use PRM as your main skill, commit to it.
Get your Arcanist mastery score at least to 40 and completely max out PRM. Go for all the skills that boost your PRM, most prominently “Mental Alacrity”.
You could then decide on what types of damage to focus on - you could go for Reckless Power and Devastation, you could also go for Star Pact and Trozan’s Sky Shard.
The first would boost your PRM much more but would require a caster off-hand to use Devastation for some devastating (hah!) burst AoE.
The second would produce a weaker PRM but would give you a strong Trozan’s and would make it possible to use a shield for more tankyness.
Devastation and Trozan’s respectively would provide you with some burst damage to complement your skill set, e.g. helping you with bosses that force you to run away from them, making it hard to use PRM against them.
Regarding the equipment you would most likely wanna go with a caster implement (probably a scepter) and a caster off-hand because they just give you superior damage stats.
You could use a shield, enabling you to use many more Soldier skills, but there are not many shields that would even roughly compare with most caster off-hands in terms of stats provided that are useful for a PRM build.
You could also use a two-handed weapon but the situation here is not much better.
All of those are possible though and there is late-game equipment for those styles of play.
B) If you want to really make use of the Soldier mastery, let go of PRM.
In this scenario you might go for a Cadence build doing mostly physical and elemental damage.
You could also decide to have a mix, with "Blitz"ing into the enemy, using Olexra’s Flash Freeze followed up with a “Wrath of Agrivix”-transformed Callidor’s Tempest as a strong AoE combo, then using “Cadence”-powered default attacks to finish of the enemies.
You could also go for a build that uses Callidor’s as it’s main skill, not using default attacks (like with Cadence) at all.
You could also decide to either use one-handed weapon and shield, dual-wielding one-handed weapons, or using a two-handed weapon; either melee or ranged.
There’s many more options and all in all this route would offer much more distinct possibilities.
Some very general assessments:
- Put at least one point in Inner Focus, Arcane Will, Nullification and Mirror of Ereoctes. Especially the last two would help you safe your character’s life over and over again; they are very very strong, no matter whatever build you play. I mean, “Mirror” is the only mastery-given skill that e.g. let’s you walk through ground patches of aetherfire or acid unharmed, so even if you only use it for utility it is literally unrivaled.
[li]Also, even though we are talking about a hardcore character here, I would not max out Maiven’s, at least not if you are lacking damage and energy regeneration and don’t absolutely need it. Putting only three points in it will give you half the damage absorption that it’s max level gives you, with only a third of the energy cost per second.[/li]After all you got the Soldier Mastery for tankyness; and “Mirror” for critical situations. Seriously, just thinking about it, you are playing a hardcore character - go get Mirror of Ereoctes!
[li]You can get loads of damage via devotions, yet, if I got you right, you don’t have taken any devotion that grants you damage. E.g. take a look at “Rhowan’s Crown” (great elemental damage plus resistance plus enemy resistance reduction) or at “Viper” (enemy resistance reduction plus resistance plus OA) or “Widow” and “Spear of the Heavens” (for aether and lightning damage and enemy aether/lightning resistance reduction).[/li]In any way I strongly suggest you get some devotion proc for your main skill to help you deal more damage. With PRM you could assign “Elemental Storm” from the Rhowan’s Crown constellation to your PRM and use your “Dryad’s Blessing” from the Dryad constellation on your Olexra’s.
- Fighting Spirit is nice, but it’s rather suboptimal for a ranged character that ought to “stay out of trouble” anyway, so I wouldn’t put that many points in it. Especially as you have access to Arcane Will, which is the more reliable ability anyway. The OA is nice but you also have access to Inner Focus, so you don’t necessarily need Fighting Spirit for that.
