Ziggy on Herald of Agony and Pathfinder:

Sorry... it's a video. https://www.youtube.com/watch?v=8Ax1_cOgcjM

thx for sharing

Thanks for sharing the link.

It seems they made poison great again.

*insert OMGI'msohappy meme*

herald bow minion? it feel slow as hell and centric focused on few build that's sad.
i would like to get an general herald skill by far!

One slight issue is new chaos/poison pathfinder's branch doesn't synergy well with any other pathfinder ascendancy notables. Other notables are providing bonuses to elemental damage which is opposite to chaos damage by game design, and Master Surgeon is kinda useless. Yes those notables are also providing bonuses to flask charges and elemental ailment immunity but still other bonuses are lost if character is going to use new chaos/poison notables.

I just hope they will add this mechanics to scion/pathfinder

For those who dont want to watch the video:

Herald of Agony
Mana Reserve: 25%
Requires lv16, 41 dex at gem level 1
Grants a Buff giving more Poison Damage and a chance to inflict poison. When you poison an enemy while you have this buff, you gain Virulence and summon an Agony Crawler Minion that uses Projectile and Area attacks. You will lose Virulence over time, at a rate which increases the more Virulence you have. The Agony Crawler will die when you have no Virulence.
Maximum 1 summoned Agony Crawler
Grants 20% chance to Poison on hit
Grants Virulence when you Poison an Enemy
Grants 10% More Poison Damage
Agony Crawler has 2% increased attack speed per Virulence you have
Agony Crawler has 10% increased damage per Virulence you have.
Agony Crawler has 2 to 3 added Physical Damage per Virulence you have.
(All above are for lv1 gem, not sure how any of them scale with gem level or quality)

In Video, Ziggy D Says Virulence has a maximum of 40 stacks
Crawler does 60% Physical / 40% Chaos Damage
'at maximum Virulence is comperable to the strongest minions of a summoner build without any other investment in minions'
It has 2 skills, one similar to Split Arrow, and the other a barrage of aoe projectiles.
The Crawler can be supported by Supporting the Herald Gem, but it does increase mana reservation.

New Pathfinder Keystones:

Nature's Reprisal (Replaces Master Herbalist)
30% increased chaos damage
Gain 10% of physical damage as extra chaos damage
10% of physical damage converted to chaos damage
When you kill a poisoned enemy during any flask effect, nearby enemies are poisoned (only spreads the 1 most powerful poison on the killed enemy, and it's duration is refreshed)

Master Toxicist (New Ascendancy Keystone added, requires Nature's Reprisal)
15% more chaos damage with attack skills
Chaos Skills have 50% increased area of affect
You lose Virulence 50% slower
Poisons you inflict during any flask effect have 40% chance to deal 100% more damage.

Looks like this old thing is about to come into prominence again.

Herald of Purity and Herald of Agony here both seem to be set up to deeply reward heavy support link investment, but it's hard to extensively support a reservation skill...unless, y'know, its reservation cost becomes fixed and ignores any/all support gem modifiers.

Legit curious to see what might come of this, especially given how easy it is to scale this thing quickly. Quill Rain with Tornado Shot > GMP > Chain > Faster Attacks - poison stuff forty times in less than a second, max out your 6L Crawler and watch it go to town. Could be a very interesting take indeed on the ol' Ranger w/Pet build that's otherwise been sorely lacking in PoE.

For supporting the Herald of Agony

The coming calamity?
https://pathofexile.gamepedia.com/The_Coming_Calamity so 45% no matter many support gems on it to make that Summmon buffed. Just wish it had twice the shield for defense.

EDIT 1453R beat me to it!
