Hydromancy VS geomancy
Superior Sigil of Geomancy inflicts 3 stacks of bleeding for 10s (so 20s at 100% bleed duration).
Superior Sigil of Hydromancy inflicts chill + 3 stacks of bleeding from Deathly Chill for 5s (10s at 100% bleed duration).
So Sigil of Geomancy does double damage overall.
Surrender and serve me in life, or die and slave for me in death.
Geomancy applies longer bleeding compared to hydromancy with deathly chill. Usually reapers are taken in pairs to bounce epidemics, so chill uptime should be around 100% even without additional help from the sigil.
BUT, for open world/fractals if you dont want to use toxic focusing crystals you can use setup with 4runes of nightmare + 2runes of the trapper. Then you dont need sigil that gives 10% condi duration so you can either take sigil with 10% condi damage OR hydromancy for better chill uptime (helpfull when you have to solo something, when you are the only reaper in the group or when the boss can heal condis).

Sigil of bursting is garbage. Don’t use it in condi builds. The 6% only works off base condition damage, making it worthless, and the main reason it is never ever used in builds.
Chill on crit would net overall higher dps than sigil of bursting.
