As it stands, there's no kc that shows when you kill Hespori (nor is it logged in your kill counts), and it is rare to get the seeds from seed packs, or farm patches.
I recommend adding the kc counter, (I personally want this so I can keep track of how unlucky I am chasing the bottomless compost bucket) and buffing the drop rate of Hespori seeds from seed packs and random farming. I have gone a week+ without a single Hespori seed at times.
The rate for Hespori seeds from seed packs in osrs is 5/44 (what kind of rate is that?), and on here I think I have only ever gotten them from a seed pack maybe thrice since release.
