with sedimentary being the most commen geodes how rare are morphic ones? and others as ive not had any but most my friends have atleast 3 by now and ive been mining longer than them can sumone explain if there is a setting to turn em off or watever??
You have the same chance of getting a geode every time you mine ore. Sedimentry geodes are for the 8 lowest "metal ores" (up to and including rune) Igneous geodes are for the 9 above rune (so Orichalcite upwards)
There is a 1% chance that any Igneous geode is changed to a Metamorphic one. Sedimentry cannot do this - so you will only get Metamorphics on Orichalcite and higher.
