^ True, it's a challenge, but it's doable even with low stam. Stamina-regen gear such as the grass crest shield and munching on green blossoms help. Might be too difficult for a new player who's more into archery/magic/dex playstyles though, I grant you.
Casanova: can't speak for everyone but I'm sure you aren't a bother at all.
That sorcerer looks decent for a magic build. Your strength is a bit high,
but there's an excellent late-game INT-scaling weapon that requires 16 strength to wield so it'll come in handy then (it also requires high INT so it's great for magic builds). Don't level it up more than that, though. Focus on more VIT (that's never a mistake to level up until at least 40-50, to be honest), find weapons that scale with dex or int and level that up. Which stat you want to level up depends on the weapons and spells you want to use. If you want fast and strong melee with magic and bows as
backup, go with higher dex and endurance and level up an estoc or a balder side sword (you might need to farm it from the Balder knights in the Parish, but it's not that bad and it's
very good weapon) ot wait until you find a falchion. You can also use very good bows with these stats. I'd focus on the normal +10/+15 upgrade paths.
If you want to focus on sorcery and use
melee as backup, level up INT and ATT more and focus less on dex and endurance (though endurance, like vitality, is never really a mistake to level up until you reach 30-40 -- don't ever go past 40 though, not worth it on your build at all). You can upgrade any weapon to the magic/enchanted path later which will scale with INT, or you can just use elemental weapons which are probably better anyway. Fire bows with fire arrows are good on any builds, but if you prefer scaling for long-term, go with a magic bow once you get green titanite shards.
For armor, I'd recommend keeping light armour for mobility (the pyromancer and wanderer sets are excellent, and found in Blighttown, you can also use the Black leather set in lower Burg in the meantime) and use the Wolf ring for some poise. While it's not cheap at early-game (20k souls IIRC), do buy the Bellowing Dragoncrest ring from the mage vendor. That'll be your other main ring if you want to use magic. Also works for boosting pyromancies!
Good luck!
