I am a new player and don't have any first hand experience to inform my decision. I am planning to play a gish, starting out as a Fighter at level 1, with the end point being a Fighter (EK 8)/Wizard (War Magic 12). I'd be looking to milk the EK's War Magic for all it's worth as a character who will comfortably wade into melee more often than not, whilst also cultivating a wider range of spells in terms of both flexibility and level range. I'd want to use said spells both as combat options and for RP or adventuring (by which I mean the non hack-and-slash) purposes.
Character Build Criteria
- I want a lot out of this character concept (both in terms of combat variety/flexibility/flavour and RP).
- My group will be using Point-Buy. We won't be rolling for HP.
- When it comes to ASI, Strength is preferred. I will be wielding a greatsword.
- Intelligence(For the sake of my Spell Save DC) will need some attention
- I am looking to pick up four feats in the course of my 'career'(with the first being from variant Human).
With the above in mind, I find that I am taxing my Constitution stat to make ends meet. As a result my stat spread at character creation looks like this:
STR 15(+1) | DEX 8 | CON 14 | INT 15(+1) | WIS 10* | CHA 8
*(will eventually also be taking the Resilient feat for it)
I had reconciled myself to keeping Con at 14.
I now find myself deliberating cutting yet another 2 points from it to pad both my -1 Dexterity (mostly due to a concern of Dex saves being more important than I had originally surmised) and -1 Charisma (to not undermine some RP interactions I'd wanna try), bringing it down to a flimsy 12.
I had originally decided that one of my feats would be War Caster, even though I'll be using a greatsword, to better protect my concentration spells, as well as for the flavour/options that turning OAs into spells seems to provide.
Although I do see how my Arcane Tradition's Arcane Deflection can overlap with these 2 features, I realise that a Constitution of 12 is probably taking it too far. Which finally brings me to my two questions.
Firstly, in light of all of this, should I drop War Caster and run with Tough instead to shore up the atrociously low HP I'll have? I am asking this regardless of whether I choose to run with a Con of 14 or one of 12.
And secondly. Is it even feasible for a martial caster to hope to get by with these amounts of HP?
I am not sure if the AC (and minor saving-throw bonuses) from my combination of spells and class features (Shield or Arcane Deflection/Haste or Greater Invisibility/Durable Magic, to name some) grant me enough HP/Defense to sustain this character from 1-20.
