Notes from author
The stats are allocated for two different "forms" of Gwyn. The first is "Lord of Sunlight", the second is "Lord of Cinder". Both designs of the build use different weapons and spells, with 1 ring slot for anything you want to use. The other is for the RoFaP.
----------------------------------------------------------------------
Lord of Sunlight:
R1 Weapon: Great Lord Greatsword
L1 Weapon: Darkmoon/Sunlight/Ivory Talisman
Rings:
RoFaP *Mandatory
"Wolf Ring" or "Ring of the Sun's Firstborn" are my recommendations
Attunement Slots:
Sunlight Spear (2 slots)
Great Lightning Spear
Lightning Spear
The 45 dexterity on the build improves the speeds of all of the lightning spears, so it isn't pointless on the faith side. Faster speeds leaves less openings.
----------------------------------------------------------------------
Lord of Cinder:
R1 Weapon: Greatsword
L1 Weapon: Ascended Pyromancy Flame +5
The reason I have the "Greatsword" set for the weapon instead of the "Great Lord Greatsword" is because it is buffable with Charcoal- Pine Resin. This is to imitate the appearance, fire damage, and reach of his attacks. In exchange, you are forced to 2-hand the weapon.
Rings:
RoFaP *Mandatory
"Wolf Ring" or "Bellowing Dragoncrest Ring" are my recommendations
Attunement Slots:
Whatever Pyromancies you want. You have 4 slots to work with, so keep that in mind. My personal favourites are:
Great Chaos Fireball (2 slots)
Fire Whip
Fire Tempest
----------------------------------------------------------------------
Keep in mind this/these(?) build(s) are not meant for PvP, but are more for roleplay purposes. These are inefficient for PvP, but if you really want to, you could get it to work with some finesse if you're really good. Those are my two cents, though.
If you decide to use this, I hope you enjoy it!
