Synthesist question

Quote:
While fused with his eidolon, the synthesist uses the eidolon's physical ability scores (Strength, Dexterity, and Constitution), but retains his own mental ability scores (Intelligence, Wisdom, and Charisma). The synthesist gains the eidolon's hit points as temporary hit points. When these hit points reach 0, the eidolon is sent back to its home plane.

gains the eidolon's armor and natural armor bonuses and modifiers to ability scores.

I've bolded the parts I'm looking at - I can wrap my head around most of the issues with the Synthesist, but I'd like people's view on this particular point.

10th Summoner with Con 10, Huge Eidolon with Con 21 (13 Con base, +8 for Huge).

Assume that the summoner has a base hp of 8+(9*5)+0 from Con+10 Favoured Class = 63 hp when not fused and a base hp of 8+(9*5)+50 from 21 Con+10 Favoured = 113 hp when fused (Because he uses the Eidolon's adjusted Con while fused).

Does this mean that if (through using Fused Link to prevent damage) he brings his own hp below 40 hp at any time should the eidolon be banished/dismissed/sent back to it's own plane somehow, he instantly dies as the loss of the increased Con score from the Eidolon drops his hp to a negative score higher than his base Con?

YES, because he would loose that 11 point con difference aswell. Thats why you have to be careful.

Playing a synthesist who has a lower con unfused than fused is very risky. You can never actually use the extra hitpoints without a severe risk of dying.

You do have a choice to go the other direction though. If you have a higher con while unfused, you will actually gain hit points when you eidolon goes away. This can mean hitting zero hit points, passing out, then instantly regaining consciousness when your con goes back up.


Synthesist isn't the only class with this problem. Any spell that buffs constitution then drops could cause this. Also, doesn't this potentially pop up when a barbarian rages or something?

Yes to both, and a lot of barbarians used to die this way, until they were given options to mitigate the problem.

not understanding why you are getting a double dip into FC for hp though. Can you explain?


How am I double dipping on HP from Favoured Class? a 10th Level Character would have 10 hp from Favoured Class if they took hp every level. The only thing that changes between the two examples is the 50 hp from the increase in Con due to being fused.

I see what you did. you added your +10fc to the temp points of the synthesist. I dont do that because it is added to the real points of summoner, so would be 63/103. The way you have it, it looks like your double dipping 63/113.


/sigh.

No, the +10 FC is not added to the Temp HP from the Eidolon, because I've not included that calculation in any of my posts because it's IRRELEVANT to the discussion...

RAW the Synthesist uses the Eidolon's Con score to determine his HP's when fused. This is HIS HP's, not the Temp HP's from the Eidolon itself.

If it makes you feel any better, I'll do the full blurb.

Summoner's HP, not fused, Con 10: 8hp (Max HP from 1st Level Summoner at d8) + 9*5=45hp (Averaged from 9 Levels of Summoner at d8) + 0 hp (From Con score of 10) + 10hp (From 10 levels of Favoured Class Bonus) = 63hp.

Summoner's HP, Fused, Con 21 (From Eidolon's Con Score): 8hp (Max HP from 1st Level Summoner at d8) + 9*5=45hp (Averaged from 9 Levels of Summoner at d8) + 50 hp (From 10 Levels of Con score of 21) + 10hp (From 10 levels of Favoured Class Bonus) = 113hp.

Eidolon's Temp HP, Fused, Con 21: 8*6=48hp (Averaged from 8 HD of Eidolon - 10th Level Summoner, remember? - at d10) + 50 hp (From 10 Levels of Con score of 21) = 98hp.

As I said, the Temp HP from the Eidolon part of the Synthesis does NOT come into the equation of how much REAL HP the Summoner has AT ANY TIME...

If you are playing a synthesist, you are most likely not going to be casting a lot of spells that require a high DC.

Build for Con: start with an 18 and build up to 22. As long as your charisma is high enough to cast your good.

At lower levels you will gain a substantial boost to hit points if your Eidolon goes away. At higher level, you'll break even, rendering this a moot issue.


Yeah, I wouldn't be going higher than 15/16 Charisma, as I'd be taking 6 levels of RAI Titan Mauler for a non-optimised local non-PFS campaign.

Thinking Colossal Scythe on a Huge Biped Synthesist ;)


Usually multiclassing with summoner, synthesist especially, isn't worth it. Since the eidolon won't be gaining evolution points, or growing in power. With 6 levels of Titan Mauler, and 13 or 14 levels of synthesist I don't think that massive weapon is worth the trade off, but maybe I'm wrong.

AH, my mistake. Thanks

This is a freaking awesome concept... I am going to have to steal it :)

Aw, for a second there I was thinking 'OOH what about a huge synthesist dipping Barbarian for Body Bludgeon???' but then I realized you need level 13 summoner for huge synth and level 10 barb for body bludgeon... /cry

Yeah, it's in no way an optimised build - I think I'd piss the group off if I optimised and facerolled the campaign.

I just wanted to have a huge character running around with a colossal weapon for a giggle.

Let me know how it turns out?


Hmm, from what I am reading unless I have something confused that is a no-go...
if you use an oversized weapon it counts as a step up on the one-handed/twohanded etc scale.. and you aren't allowed to use it if it would make it anything other than light, 1h, or 2h....
So no oversized 2 handers, and no undersized light weapons, basically.
You could do a gargantuan 1hander or a colossal light weapon though.

Multiclassed synthesists are in serious danger of sucking in combat as by RAW the fused synthesist uses the eidolon's BAB, not their own.

As it's not a PFS campaign I'll be using the RAI Titan Mauler Rules from Jason Nelson: http://paizo.com/forums/dmtz4qa7?Titan-Mauler-what-can-and-cant-it-wield#3

That got FAQ'd to work the same way as Monk FoB, ie you still add the BAB from other classes as normal.
