Pros:
- Greatshield blocks most magic damage
- High Poise
- High Damage output
- A bit of range (pike)
- High Vitality
Cons:
- Slow Roll
- Susceptible to back-stabs if not careful
- Easily parried when using the dragon tooth
After some PvP, I noticed this build was pretty effective against most opponents. Adding pyromancy may be a good way to avoid getting parried.
