Mercury as a new liquid + interaction with Sulfur Geyser

I suggest adding Mercury as a new rare liquid in the Chaos Cubed update. Basic mechanics: · Mercury can be transported with a bucket · It generates in small pools underground, mostly in Sulfur Caves · Players standing in Mercury get Poison I (same as freezing from Powder Snow) · Above Mercury, silver particles occasionally appear Poison cloud (区域效果云): · The silver particles act like Dragon's Breath (area effect cloud) · Any entity entering the particle cloud gets Poison I for 1–2 seconds · This makes Mercury dangerous even if you don't touch the liquid itself Sulfur Geyser interaction (重要联动): · Currently, a Sulfur Geyser activates when a liquid is placed on Sulfur blocks · If Mercury counts as a liquid, it will trigger the geyser · The geyser's upward airflow should push the Mercury particle cloud upward · Result: a vertical silver poison tower rising from the geyser Why this fits the Chaos Cubed theme: · It uses existing mechanics (Powder Snow freezing, Dragon Breath clouds, geyser airflow) · Low development cost — mostly copy/paste with parameter changes · Creates a chaotic but logical interaction players can discover themselves Expected behavior: · Mercury on Sulfur → geyser activates → particle cloud rises → upward poison zone appears · Great for traps, exploration hazards, and new defense builds Thank you for considering this idea.
