10 sentinels HoP Ascendant(necro/guard) 100% phys->Chaos idea

Hello this is my first post in this subredit. It will be my third league. While looking for interesting options for the next league, I have made a strange HoP build. "Budget" 1-5ex.

​

Basic info:

1. Stacking medium cluster jewels (Pure Agony(+1sentinel), Disciples(1% phys red per sentry)).
2. 10 sentinels(+fortify). 25Lvl HoP (chest+cold iron point)
3. Bone offering for some block/spellblock.
4. Lone messenger keystone(no aura from skills).
5. Two curse limit.
6. 4500hp/770ES 90% phys red 75% block 35% spell block, res capped.
7. Sharing charges with the gang.[Updated][Removed charges on minions from PoB calc]
8. Killing worms to summon the guys and get power charges.
9. Cold snap for charges generation,cruse on hit punishment and warlord mark.
10. Cyclone power charge on kill, (worms).
11. Leper's Alms shield for ailment reflection.
12. Triad Gloves 25% phys to chaos for minions per white socket could get 4 white with new crafting system.

Gems: 6L HoP -> Multistrike,Minion Damage,Mele phys damage,Ruthless,Fortify.Curse on hit 4L: Cold snap -> Punishment, Warlord Mark.Cyclone 4L -> power charge on crit, nightfall, fortify.Spell Totem 3L -> Wither, multiple totems.Summon carrion golem/spectre 4L -> Minion Life, Meat shield.

Needed unique chest -> https://pathofexile.gamepedia.com/The_Coming_CalamityCold iron point, leper's alms, triad grip, 1x circle of guilt, worms flask.Bandits: 2 passives

It shows me more dps if I go for pure phys HoP.

For example:Pure chaos: 1 sentinel does 500k dps.Pure phys: 1 sentinel does 700k dps.

Is chaos damage really better or not, since it bypasses defences?[Answered]Does Unholy Might(from the Grave intentions notable) still get its benefit for minions, even when the whole phys is converted?

Most of the items are not expensive in this build. But getting all these cluster jewels at the beginning of the league will be a bit painful.

Do you guys have any suggestions for improvements?
