Huge carry capacity allows for awesome defenses and poise while still able to use Havels Greatshield and any weapon lighter than a black knight Greataxe and a Giants halberd using ascended +5 pyromancy with 6 spell slots means you can incinerate any boss easily and fuck with PvP enemies did I mention the huge poise and the games best shield the only drawback is having to use both the ring of favor and protection and Havels ring is reduced by the huge bump in health and stamina making you extremely hard to defeat
