Why does this say there is a passive 5 madness build up? I tried to cause that to happen with both Frenzyflame incants and non frenzy incants but nothing happened.

really? this is the dex seal we get?

Genuine question: If you managed to max all four stats, how high does this thing's scaling get? I feel like it's probably still not as good as some of the others, but I'm interested.

Pve wise, having 2 of these or having 1 of them as an off hand with a high faith seal is the way to go. A lot of damage stacking and flexibility is a must for PvE as a faith caster. But if you plan to pvp…
Definitely recommend to off hand this and use the dragon commission seal if you plan to do any kind of PvP. The arcane scaling in the dragon seal improves the chaos status effect noticeably good and it becomes great against other players (especially against high poise builds since most high poise armor lack focus resistance). While you may do less damage, procing madness easier is a must since it it gives you free dmg, stuns and applies pressure to your foe whenever you build up status. You even have access to most weapons with the use of occult infusion. (preferably with a weapon with built in bleed).

Not me accepting the curse of an eldritch outer god that seeks to eternally torment every living being so I can reinvest points from endurance and use some basic utility magic while light rolling
