Recently, herblore secondaries were added to the barrows drop table, however they are actually quite rare, 6.1% chance of getting ANY secondary from a completion, but the chance of getting a specific one, drops to 0.5 - 0.8%.
My suggestion would be to add in things such as the tower of life. https://oldschoolrun...eature_Creation
For example, to spawn and kill the spidines you need 1 raw sardine, and 1 red spiders egg, which when killed gives 2-6 red spiders eggs, in osrs using the ardougne cloak, will make them noted, that might not be needed in alora since the cape has a use already, but it is a stable, controlled method of getting red spiders eggs that doesn't require killing a boss in the wild, rng, or any risk of your items or status for UIM and HC accounts.
This could be made even better for farming them if other custom drops could be added to the other ones, in osrs theres things like Newtroost which gives eyes of newts, theres a shop with those for all accounts so that wouldn't be needed, however some of the ones with no use in alora could be changed to require, maybe a crushed nest, and then when you kill the creature (im thinking a mini mole ) it gives 2-6 noted crushed nests in return, this could be a huge improvement for modes such as UIM, HC, even GIM and EIM because of how difficult some of these can be to get as a lower combat level.
One of the concerns for this idea would be that it would be way too fast of a method for getting these secondaries, if the idea is to keep the method slow it could give 2-3 honestly, as long as its consistent i would be using it way more than risking my items out in deep wilderness.
This would make the game have much more early game content, which i feel is lacking, and even higher level restricted accounts could use this, it would not be the fastest method of getting the secondaries as some bosses drop 100+. but it would open doors for accounts with lower combat, and people who don't want to be in the wild. If anybody has any other ideas that go alongside this please feel free to let me know, i think this would change the game for the better and make it less dependent on high level content for skilling items.
