Fair do's - yes, that's fully upgraded now.
No, I "ascended" the glove after +15 and then upgraded that to +5, isn't that full?
Halfway is a reasonable assumption but it does ramp up from here on in. Though you'll acquire some interesting stuff and unlock useful abilities so don't worry about it.
When you say fully upgraded pyromancy, do you mean your glove is on +15? Because that's not fully upgraded.
I believe (but someone will have to clarify this) that dex only increases the speed or magic and miracle casting, not pyro, but again, someone will correct me if I'm wrong.
What weapon(s) are you currently using and what are your stats looking like?
Also, what have you been doing with the firekeepers souls?
I'm using the Divinie Gargoyle's Halberd +5
I think I have..
I'm using the heater Shield+5 although I switched to Eaglie Shield in Sen's, I'll need to check my armour later, trying to keep it light.
I think I only got one Firekeeper Souls and upgraded my Estus Flask with it in firelink shrine before the poor mite was murdered.
Hm, not sure on the divine. That's more suited to undead (not normal undead, but skeletal undead). I'm wondering whether a different path would benefit you more.
Heater shield +5 is a good all rounder. Might want to get something a bit heftier out later, if you're a 'blocking' type of player as opposed to a rolling type of player
You probably want to keep an eye out for those firekeeper souls. There's one at the parish (assume that's the one you used to upgrade your estus), but there's also one at blighttown, where you've obviously already been. Can take it to +7
If you're ever thinking of using magic for spells, you need to go back to sens and unlock the npc. Also, while you're there, unlock the shortcut, saves a lot of pain
