here are some simple profit estimates from zulrah from 1 full trident use
my method includes:full void (mage/range) swamp trident, arma cbow, occult, arcane shield
estimated loot worth with no rare drop
~8-9m
expenses including full trident of swamp used+food and potions with some deaths included
~2.5-3m
your profit frum 1 full trident of the swamp use should be
~5-6m
*takes about maybe 5-6 hours to use up all 2500 charges at zulrah depending how much you afk
with tanzanite fang drop profit = ~9-10m
ive tracked 3 full trident of the swamp uses and thats the average profit i got personally
PROS OF ZULRAH: fights last about 2-3minutes average
can afk after every kill if needed
no need to stay logged in for hours like in bandos trip etc
can claim items lost on death even after 30minutes
